Rosco Latex Marley Dance Floor Adhesive - Commercial-Grade Permanent Install Glue for Porous Concrete Subfloors
A commercial-grade latex adhesive for permanently bonding marley and sheet-vinyl dance flooring to an approved interior substrate. This aggressive, pressure-sensitive formula is built for glue-down installations where the floor needs to stay put under heavy studio use. It is Green Label Plus Certified and contributes to LEED low-emitting materials credits, with a low-odor profile that makes it suitable for use in occupied buildings. Key Benefits Green Label Plus Certified Contributes to LEED (low-emitting materials) Up to 2 hours of working time Low-odor formula suitable for use in occupied buildings Aggressive, pressure-sensitive latex bond for permanent (glue-down) installations Installation Instructions Step 1: Spread the adhesive onto the substrate using the correct trowel or applicator for the job (see the spread-rate table below). If using a 1/4 inch (6.4 mm) nap roller, apply a uniform layer to both the substrate and the back of the flooring. Step 2: For smooth products, back-rolling the troweled adhesive with a 1/4 inch nap roller may be needed to prevent the trowel ridges from telegraphing through. Step 3: Allow enough open time for the adhesive to flash off before placing the flooring. Step 4: When the adhesive has flashed properly, the trowel valleys will be clear. If a nap roller was used, let it flash until it is almost clear. Step 5: Protect the exposed adhesive from dust and debris, which inhibit proper bond and reduce tack. Step 6: Lay the flooring into the adhesive and roll in both directions with a minimum 100 lb (45.4 kg) three-section roller. Step 7: Allow no foot traffic for 24 hours after installation, and allow 72 hours to fully cure before placing heavy furnishings or allowing heavy traffic. Spread Rate Coverage depends on the applicator used. Real spread rate varies with temperature, humidity, and substrate porosity. Applicator Recommended Use Coverage per Gallon U-notch trowel, 1/16 x 1/32 x 1/32 inch General installation 200 to 250 sq ft Square-notch trowel, 1/16 x 1/16 x 1/16 inch Fitness flooring 100 to 120 sq ft 1/4 inch (6.4 mm) nap roller Reduced-porosity substrate (applied to both surfaces) 60 to 70 sq ft Open time: 30 to 60 minutes. Working time: up to 2 hours. Specifications Color: off-white Solids: 55% VOC: less than 20 g/L Weight: 8.5 lbs per gallon Shelf life: 2 years, stored unopened at 73 F Storage: 65 to 85 F, kept dry and out of direct sunlight in a well-ventilated area Application conditions: 65 to 85 F Substrate and Concrete Requirements For permanent installations over concrete, the substrate must meet the following limits: Maximum MVER of 8 lbs per 1,000 sq ft per 24 hours (ASTM F1869) Maximum 90% relative humidity (ASTM F2170) Maximum 10 pH (ASTM F710) Clean Up Clean fresh, wet adhesive off the flooring and tools with water. For cured adhesive, scrape first with a plastic putty knife, working carefully to avoid damaging the floor, then remove any remaining residue with ethyl alcohol on a clean, dry cloth. Limitations For interior installations only. Protect from freezing. Avoid prolonged exposure to low temperatures, and do not exceed five freeze/thaw cycles. If frozen, do not stir until the product is completely thawed at room temperature. Not recommended for metal or fiberglass substrates.

How to install
A permanent latex glue-down for bonding marley or sheet vinyl to an approved interior substrate, best handled by an experienced installer.
-
Trowel the adhesive
Spread the adhesive onto the substrate with the correct notched trowel. A 1/16 in U-notch covers about 200 to 250 sq ft per gallon, a square-notch for fitness flooring covers about 100 to 120, or use a 1/4 in nap roller on both surfaces for about 60 to 70.
Tip · Confirm the substrate is within limits first: MVER up to 8 lb per 1,000 sq ft over 24 hours, RH up to 90 percent, and pH up to 10.
-
Back-roll smooth products
For smooth marley, go back over the adhesive with a 1/4 in nap roller so the trowel ridges do not telegraph through to the surface.
-
Allow open time
Let the adhesive flash off for 30 to 60 minutes until the trowel valleys are clear before you set the flooring.
-
Lay in the flooring
Set the marley or sheet vinyl into the wet adhesive, positioning each piece carefully while you still have working time.
-
Roll in both directions
Roll the full floor in both directions with a minimum 100 lb three-section roller to seat it fully into the adhesive.
-
Let it cure
Keep all foot traffic off for 24 hours, then allow 72 hours to fully cure before moving heavy furniture onto the floor or opening it to heavy traffic.
Tip · Clean wet adhesive with water. For cured adhesive, scrape with a plastic putty knife, then use ethyl alcohol.
Common questions
What installers ask most about this adhesive.
Is this a permanent bond or can I use tape instead?
This is a permanent glue-down adhesive that bonds marley or sheet vinyl directly to the substrate. If you need a temporary or portable install, use floor tape along the seams and edges instead.
How much area does one gallon cover?
Coverage depends on the trowel. A 1/16 in U-notch covers about 200 to 250 sq ft per gallon, a square-notch for fitness flooring covers about 100 to 120, and a 1/4 in nap roller applied to both surfaces covers about 60 to 70.
What does my substrate need to meet?
This is for approved interior substrates only. Over concrete, the limits are MVER up to 8 lb per 1,000 sq ft over 24 hours, relative humidity up to 90 percent, and pH up to 10. It is not for use on metal or fiberglass, and it should be protected from freezing.
Is it low-VOC or studio-safe?
Yes. It is Green Label Plus certified, low odor, and contributes toward LEED credits, which makes it well suited to interior studio environments.
How do I clean up adhesive?
Clean wet adhesive with water while it is still fresh. Once it has cured, scrape it off with a plastic putty knife and then clean the residue with ethyl alcohol.
How long before I can use the floor?
Keep foot traffic off for 24 hours after installation. Allow a full 72 hours to cure before placing heavy furniture on the floor or opening it to heavy traffic.
