This flooring adhesive with moisture and sound barrier provides a moisture barrier to protect your floor from any moisture transmitted from a sub-floor, as well as filling in any cracks or ridges in the concrete.
It has an ultra low VOC content and is low odor, so you can relax knowing that you are using the safest possible adhesive product. It is also extremely elastic so it allows the boards to expand or contract without having a detrimental effect.
This adhesive really is the all in one solution to installing a perfect, long-lasting floor.
- -Retards Moisture Vapor Transmission from Concrete Slabs
- -Crack Bridging
- -Low Odor
- -Excellent Green Grab
- -Does Not Contain Water
- -Suitable for wood, bamboo, and engineered floors
- -Elasticity allows wood to expand and contract without stressing floor
- -Must be applied with a 1/4" wide V-Notch trowel
This is a single component, water free, polyurethane adhesive formulated to bond engineered, solid and bamboo flooring to concrete, plywood and other approved substrates. It is also designed to have a low permeability to reduce moisture vapor transmission between concrete sub-floors and hardwood or Bamboo flooring. This product develops a permanent bond and remains flexible to withstand expansion and contraction of the flooring.
It is designed to flow slightly so that gaps between trowel ridges will close and create a continuous polyurethane membrane. When applied as directed for subfloor moisture protection it will prevent damages caused to flooring from moisture in the substrate. Is flexible and will bridge in-plane cracks up to 1/8 in wide in concrete.
The manufacturer recommends allowing the adhesive to cure for 12-15 hours before walking on it, and 24 hours before moving heavy furniture back into place.
It is also ideal for permanent glue-down installations of plywood subfloors over concrete and for ceramic or stone tile inlays. It may be used over cement patches, cement self-leveling underlayments or screeds; properly prepared existing ceramic tile, well bonded sheet vinyl or VCT tiles existing cement terrazzo, underlayment grade chip board and gypsum concrete that has a minimum 2000 psi mix design for engineered flooring and 2500 psi mix design for solid and bamboo flooring. It is suitable for the installation of flooring over electrical warming and radiant heat systems.
This product exceeds the VOC requirements for Southern Coast Air Quality Management District (SCAQMD) for wood flooring adhesives and therefore may contribute to the qualification of a project for LEED NC V3 certification for Indoor Environmental Air Quality credits for low emitting materials ED 4.1 Adhesives and Sealants.
Do not use this product on subfloors with historical or obvious severe moisture problems; or those with a moisture vapor emission rate >15lbs per 1000 square feet using the calcium chloride test (ASTM F-1869) or with a relative humidity >85% when tested using in-situ RH probes (ASTM F-2170).
A NOTE ABOUT VOC'S. Our adhesives do not have any ingredients that are defined as volatile organic chemicals “VOC’s” as part of the formulas. VOC is a regulatory description for “solvent” which evaporates into the air and is considered an air pollutant. These formulas contain none, so we refer to them as zero-voc. We can calculate "potential" trace VOC values based on the vapor pressure of the individual raw materials used in the formula. Anything with a vapor pressure greater than 2 mmHG at 25C is considered a VOC for these calculations. The results are as follows:
RM12E4813 has a VOC of less than or equal to 0.77g/L
These trace values reflect the highest possible VOC content- prior to processing and evacuating at elevated temperatures.
If our website lets you add your desired quantity into the shopping cart without showing a "this item is back-ordered" pop up notification, that means the product is in stock and ready to ship!
We highly recommend reading our Shipping Policy for a comprehensive explanation of our shipping processes.
We ship most freight orders (over 125 lbs) out within 4 business days of purchase, the average being 2 business days. For faster shipment of freight orders, we offer an Expedited Shipping option at checkout however please note that this simply means that we will ship the order out the next business day - it does not shorten the transit time once shipped. For small parcel orders we offer express UPS shipping options at checkout as well; please note that for express shipping services the order must be placed by 2pm EST in order to ship out that same day, otherwise we will process the shipment the next business day. We do not ship out orders, nor do the shipping companies deliver them, on weekends.
For residential lift-gate freight order deliveries, once the flooring order arrives at the local freight terminal, they will call you to schedule your delivery appointment, which is usually a 2-6 hour window on the day of your choosing (weekdays only) when possible. All deliveries are curbside as the freight companies do not offer inside delivery.
You should follow two basic rules when choosing a wood flooring adhesive:
1) If you're gluing the floor down to plywood or other dry substrate, you'll want to use a zero VOC 100% urethane trowel-down adhesive approved for wood flooring installation. I.e. when installing over plywood or a dry substrate you don’t need the adhesive to contain a vapor barrier unless there is a crawl space, garage or other moist environment underneath. If there is a moisture concern, proceed to Step 2 below.
2) If you're gluing the floor down to concrete or any other sub-floor that may be emitting moisture, this will require an adhesive that contains a moisture/vapor barrier. These adhesives are slightly more expensive than basic adhesives but well-worth the investment. We sell an affordably priced low-VOC adhesive with vapor barrier and sound retarder that works not only for bamboo but for all types of wood floors and even some tile; many of our clients even use it on their upstairs floors to keep noise levels down. Important: always make sure to use the correct trowel style and size for the type of adhesive you select or you may not get enough coverage on the floor and this will cause the installation to fail. For example, our vapor barrier adhesive should only be applied with a 1/4" x 1/4" V Notch Trowel.
About Moisture In Concrete. Most concrete slabs emit moisture for up to 25 years after being poured, and installing a floor over such a slab is easy to do, however as with any other job done right you want to make sure you have the right tools, and adhesive, on hand. Moisture is measured in pounds on concrete slabs. Basic adhesives usually protect up to about 3 pounds of moisture. Meaning, if you test the concrete and it comes back higher than 3, you need an adhesive that contains a moisture barrier.
Keep in mind that moisture tests only test the moisture on any given day. A slab may read 8 lbs per square foot one day but then it rains for a week and the moisture rating jumps to 14. Our vapor barrier adhesive mentioned above protects your floor up to 20 pounds of moisture emitted per square foot which is usually more than enough for most slabs, however, it's still always recommended to test the slab moisture emission prior to installation using a calcium chloride moisture test kit. If you have an 'excessively wet' concrete slab or sub-floor (which emits more moisture than the upper moisture limit specification of the vapor barrier adhesive you choose), you'll need to find an unlimited vapor barrier adhesive such as Bostik Ultra-Set Single Step.
The adhesives that we sell are moisture-cured urethane adhesives. These types of adhesives cure (dry) faster when the humidity levels are higher. This is why adhesives usually come with a tack time and a cure time in relation to temperature and humidity. Thus, the same pail opened in Florida may dry in 12 hours where it may take 16 hours in Colorado. We recommend allowing the adhesive to cure at least 12-15 hours before walking on it, and 24 hours before moving heavy furniture back into place.
None of our products are brought inside the delivery location by the driver. All small parcel shipments are at the discretion and policy of the shipping company. All freight shipments are curbside delivery with lift-gate unless you specifically request freight dock delivery. Curbside delivery means they lower the pallet on the street at the end of the driveway. The drivers are not required to enter the property boundaries, although if not hazardous sometimes they’ll back up the driveway (if it’s flat and short) and drop the pallet on the driveway. Someone must be on-site to receive the delivery and inspect it for exterior damage, and then note any damage on the driver’s bill of lading (otherwise we can’t send free replacements). We highly recommend that you do not pay laborers to sit around and wait for the delivery, as the freight companies do sometimes miss appointments and they do not reimburse for such lapses. In some cases at the time of checkout, our website will allow you to add "Garage Delivery" for an additional fee, but this includes rolling the materials pallet into a carport or garage only, and terms and conditions apply.
Yes, we sell several different products that provide sound insulation - underlayment and adhesive. To see these products visit our Installation Supplies page and check out our underlayments and adhesives. Many condominiums have sound insulation requirements for flooring. There are two sound tests that are the industry standard for sound insulation: IIC and STC. We have ratings as high as 83 STC and 85 IIC for underlayments and as high as STC 70 and IIC 66 for adhesives. The biggest benefit to using our high STC/IIC underlayments and adhesives is that you do not need to buy cork or other soundproofing and then pay someone additional to install it. Just float the flooring over the underlayment or glue the floor down using the sound reduction adhesive and you can substantially reduce sound transmission between levels in your home as well as muffling sounds from footsteps.
FLOATING FLOORS. In order to choose the right underlayment you have to ask yourself two questions: Do I need moisture protection, and how much am I willing to pay for sound reduction. When installing over concrete or over a crawl space, an underlayment with a moisture barrier (usually a thin layer of plastic or foil) is a must-have. This protects your wood floor from moisture rising up and damaging your floor from beneath. These are called 3 in 1 underlayment.
What are the 3 features of a 3 in 1 underlayment?
1) Moisture/vapor barrier
2) Impact absorption and sound transfer reduction
3) Cushioning for comfort
Remember that you will still need your sub-floor to be very flat before you begin the installation, as the underlayment only accounts for minor sub-floor imperfections. The second question having to do with how much sound reduction you want is simple - all underlayments have STC and IIC ratings that tell you how much sound they block. The lower the rating, the higher the echo or knocking sound when you walk on the floor. Underlayment with a 70+ STC and IIC rating will muffle noise much better than an underlayment with a 50 STC rating. As you may have guessed, underlayments with higher STC and IIC ratings are more expensive due to the quality of the materials or thickness of their construction.
While it can be a bummer if your shipment arrives damaged – it is not the end of the world! We can easily send you free replacements for anything that was damaged in transit - all we ask is that you do not refuse the shipment and mark any damages on the receipt provided by the driver. After that, please take a few photos of product while it is still on the pallet and email them to [email protected] so we can make a record on your account. Then, please examine the items further once you've brought them inside to determine the extent of the damage, and take photos of affected areas if you require replacements. Once we receive the details and photos we will send out the replacements right away. Most of the time, installers will be able to work around the damage instead of waiting to get replacements. For more information please see our Shipping Policy page.
Occasionally you will have an item with a visible defect either in the stain, finish, or milling. Like most building materials suppliers our effective defect rate is under the industry-standard 3%. However, if you are finding that more than 3% of the product you have ordered has defects, please let us know as soon as possible so we can resolve the matter quickly.
Yes, we may be able to accommodate this, but please note that we may still apply a small shipping and handling fee to your order. Please reach out to your sales representative for details.
Yes! Some adhesives will fail spectacularly if you use the incorrect trowel size and design, so using the correct trowel(s) is a must. We currently sell two types: 1/4" x 1/8” Square notch for our basic urethane adhesive (no vapor or sound retarder) and a 1/4" x 1/4" V-Notch trowel that is used with our urethane adhesive with sound and vapor retarder. The V-Notch is designed to provide a thicker layer of adhesive so you have a complete layer/seal on the slab. Pro Tip: don’t skimp when troweling down vapor barrier adhesive or your floors will cup later! The Square notch trowel puts down about 85% coverage which is enough to hold down the floor on plywood or places where a sound and vapor barrier isn't required.
Absolutely. We’ve shipped our floors to such far-flung locations as Guam, Kenya, Tanzania, Bahrain, Great Britain, Kuwait, France, Mexico, Canada, Hawaii, and many more. Please note that international shipments may require you to procure the services of a freight forwarder at the port of discharge; most port authorities can provide recommendations for reputable freight forwarders that service your home port. Also, minimum order quantities may apply to some countries. Call your Ambient representative today at (866) 710-7070 for shipping quotes to your country!
STC and IIC sound ratings indicate the ability of a material to muffle footfall noise and reduce sound transmissions between levels. An underlayment or adhesive with a high STC and IIC rating will not only reduce sound transmission between levels more effectively, but it will also reduce footfall noise within the room more effectively. Materials with higher STC and IIC sound ratings tend to be more expensive, and sometimes thicker, than underlayments with low sound ratings.
Yes, we do provide discounts for large quantity orders. If your order falls into a category below and you do not already have a coupon code please feel free to reach out to our customer support team at (301) 498-0234 to see what discount codes are currently available:
- Flooring orders over 1,000 sq ft
- Plywood orders over 25 sheets

At Ambient we value the brave men and women that serve in our nation's armed forces and law enforcement agencies. We offer a 5% discount off all products for active-duty members of our U.S. armed forces and full-time local and state law enforcement. Clearance items and odd lots do not qualify for this discount and it cannot be combined with other promotions.
For flooring and plywood we strongly recommend ordering a sample before placing your final order, so you can ensure that the shading will be to your liking. Our flooring and plywood samples have a dye lot number sticker on the back of them. Our website checkout process will ask you to type in this dye lot number before final payment; alternatively, if ordering via email or over the phone simply mention this lot number to your Ambient representative and we will update the order with it and ship that exact lot number. If we don't have that lot number available (it has sold out) but we have a matching lot, we will ship the matching lot. If we do not have a matching lot, we will not ship your order until you approve samples of the new lot.
Please remember that photographs on our website are taken from a variety of devices and under many different lighting conditions, and are viewed on a wide range of computer monitors and contrast settings, thus we do not guarantee that any floor will match the photographs on the website. If you order your flooring sight unseen (without receiving samples first), Ambient is not responsible for light or shading variation or differences and thus not responsible for return shipping costs (which can be expensive and can vary greatly depending on where you live and the size of your order).
If you receive the order from the exact lot number you requested, or you order sight unseen (you do not provide a dye lot number at checkout), and you decide after it arrives that you want to return the order, you will be responsible for return shipping charges. For flooring orders, please see our 30 Day Money-Back Guarantee for more information.
Once adhesive cures on a wood flooring surface it is very tough to remove and may leave behind permanent cloudy/dull spots on your finish, however you can try these steps:
1. Pour a small amount of Bostik Urethane Adhesive Remover on the glue spot, or squeeze a small amount of remover from a Bostik Adhesive Remover Towel.
2. Let it sit for about 15 minutes.
3. Wipe the area clean.
4. Apply adhesive remover again to the same spot.
5. Let it sit for about a minute.
6. Use a Mr. Clean® Magic Eraser® to remove cured glue.
7. Clean the area well.
If the steps above fail, you can also attempt to wear the glue spots down using denatured alcohol, but make sure to test on a sacrificial plank first as overdoing it may also rub off some of the finish. Finally, if none of the steps above work, or you are left with cloudy spots as a result of removing the glue, you will most likely need to cut out and replace the flooring plank.
Yes you can! However you must use our urethane adhesive with vapor and sound retarder in combination with our Super Silencer underlayment. For maximum effect you can first glue the underlayment down to the sub-floor, then glue the flooring down to the underlayment. You will need a 1/4 in by 1/4 in v-notch trowel and some adhesive remover wipes are always recommended when gluing down any floor.
There are a few concrete sealer products on the market you can find via basic web search and also some glue down flooring adhesives with unlimited upper moisture limits that are suitable for these types of installations such as Bostik Single-Step. You can always test the moisture levels in your concrete using a calcium chloride test kit.
The IIC and STC ratings represent how much sound blockage there is. For example a rating of 70 is a measurement of the total sound blockage for the whole system (floor + glue) when installed on a 6" suspended slab with a ceiling system beneath. The Delta IIC is the difference in sound AFTER the barrier is put in. I.e. the Delta IIC reflects the change in impact insulation as a result of the floor and glue system. A Delta IIC of 20 is very good.

For legal businesses that qualify as a trade account (must be in the building trades), or you plan to order more than $10,000 cumulatively in building materials in the future on multiple projects, we encourage you to apply for a trade account on our B2B page. Our wholesale discounts vary depending on sales volume and can range from 5% to 35% off our retail prices. We also offer container level pricing for large projects at extremely competitive prices, and can manufacture a large array of products not featured on our website such as custom thicknesses, lengths, widths, colors and surface treatments (minimum order quantities apply).
The short answer is – it depends on a lot of factors! There are many different concrete and cement products from various manufacturers on the market today. Because the components are going to differ from product to product, there is no set time frame. Although, the product manufacturer should have instructions that may list drying or curing times. Other big factors are the humidity levels, temperature, and whether or not you have fans blowing as those can all affect curing times.
The best way to determine if the subfloor is ready to be glued down to is to use to perform a calcium chloride test to ensure the vapor emission from the subfloor in question does not exceed the upper moisture limit of the adhesive you plan on using. Take for example our very own urethane adhesive with vapor barrier and sound retarder, which can be used on slabs with moisture emissions up to 20 lbs (per 1,000 square feet). That means if your calcium chloride test results come back under 20 lbs (per 1,000 square feet), then you are good to go! But let us say your test results came back at 6 lbs (per 1,000 square feet) but your adhesive is only rated for 3 lbs (per 1,000 square feet), then your floors are very likely to cup as the moisture in the slab exceeds the capabilities of the adhesive.
The fastest method to take up cured adhesive is to use grinding machines. A clean and less toxic one is a dustless diamond grinder. If you need to scrape glue out of a smaller space, the company Sentinel makes some good non-toxic adhesive removers that will soften the adhesive to allow it to be scraped up easier.
Most glues average around 1-3mm in thickness once cured, however, the exact level can be more depending on the glue spread rate required, and the type of glue being used. Note: for a vapor barrier glue the spread rate should not be less than 2mm.
Adhesive remover wipes are designed to clean up wet adhesive before it dries. Wet glue is much more difficult to remove with soap and water, but the wipes have a special compound that helps to break down the glue.
Once flooring adhesive dries it is impossible to remove and will irreparably damage your floor finish as the topcoats will be stripped away when you remove the dried glue. Absolutely never use mineral spirits to remove any glue from our floors as mineral spirits will damage uv cured urethane finishes If adhesive dries on your finish we advise that you dump some of the Adhesive Remover liquid on the spot, let it sit for 10 minutes and then use a Mr. Clean Magic Eraser. This can get in the pores of the finish and get most of the glue off, but there is no guarantee that you may still damage the floor finish itself.
It is the responsibility of you or your installer to determine whether the glue brand you are using with our floors will suffice, and we do not require nor reject specific brands. You should be able to place a quick call to the glue manufacturer you are considering to determine whether it can be used in conjunction with hardwood and bamboo flooring.
Using a glue other than those we sell will not void your floor warranty per se as our warranty covers our floors, not the tools or materials used to install them. If the floor fails later and the reason is that it was improperly installed or the glue failed, this should be covered by your installer's warranty or the warranty of the adhesive you purchased.
We strongly suggest only hiring installers that provide a 1-year warranty on their labor as most flooring problems arise within the first 6 months after installation, and the great majority of flooring issues are installation-related.
