Liquid ProPoly® F9600 Series | Liquid ProPoly® Clear

The Liquid ProPoly® Series of products are all high solids 2 part Aliphatic Urethanes. They differ only in color and anti-skid additives.

Liquid ProPoly® coatings were formulated in 2006 to incorporate the latest advancements in polymer technology. The objective was to develop a coating with superior durability that could be used on roofs, walls or foot traffic decks, had a 1 to 2 hour pot life plus fast cure. Liquid ProPoly® has met these objectives. Liquid ProPoly® Urethanes produce a tough yet elastomeric coating that is equally suitable for application on roofs, walls and siding, storage tanks as well as foot traffic surfaces. This universality reduces product selection to choosing a color. Non skid properties are obtained by incorporating the Anti-Skid Additive prior to application.

 

Procedure consists of washing membrane to remove chalk and dirt, applying a primer coat, and lastly applying the finish coat of ProPoly. Allow three days to complete.

Materials needed:

Scrub Brush with extension handle

Detergent and water hose

Rubber Squeegee with extension handle

Sponge rubber roller with extension handle

1 1⁄2” wide masking tape

ProFlex Primer

Liquid ProPoly

MEK (Methyl Ethyl Ketone) solvent for clean up

Surface Prep: (2-3 hours)

Wash membrane using detergent and scrub brush. Flush with water and let dry overnight. Wipe old caulk with

MEK and rag. Remove any brittle caulk and replace with new material where needed.

Primer: (3-4 hours)

Apply masking tape to perimeter of roof. Attach tape at edge only and let rest extend away from side to form a gutter. Mix Parts A & B of ProFlex Primer and add approximately 25% of MEK Solvent to permit application of a thin coat. Mixed material must be removed from container within 45 minutes to avoid solidifying. More time is available for spreading primer when it is on the roof and heat from chemical reaction can dissipate. Spread primer at a rate of 200 square feet per gallon so only a thin coat is applied to the EPDM membrane. Let primer cure for 3 days.

Finish Coat:

Wait until surface moisture has evaporated before proceeding. Mix Parts A & B of Liquid ProPoly but do not add MEK thinner. Product is easy to spread as is. The addition of MEK is acceptable but will result in a thinner dry film and also extend the pot life. When Liquid ProPoly is spread at a rate of 70-90 square feet per gallon a dry film of 16-20 mils will result. This is equivalent to 4 to 5 sheets of copy paper in thickness.

Application Procedure:

Pour some of the mixed ProPoly on roof surface, distribute with rubber squeegee and follow with sponge roller to even out wet film. Start at front and spread side to side 3 feet at a time, and work toward rear. Use roller to coat up to masking tape. Liquid ProPoly should achieve a tack-free surface in 3-4 hours depending on temperature. Masking tape can be removed after 4 hours. Clean drips and splatter from RV using MEK and a rag.

Surface Preparation:

1. Substrate to be coated must be dry and free of dirt, debris and loose or peeling paint, asphalt based coatings must be removed.

2. Make any necessary repairs to ensure a structurally sound substrate prior to coating.

3. Corrosion on steel must be primed prior to application of Liquid ProPoly®

4. Repair masonry with epoxy compounds such as ProFill®, Butt Putty® Crack Filler Gel or Proflex Flexible Epoxy®.

5. Prime Substrate with Proflex Primer® F1501 White or Proflex Primer® F1500 Clear according to the above guidelines and label instructions.

Coverage:

Theoretical coverage is 1426 ft2/gal at 1 mil dry film. A 6 mil dry film will result when product is spread at 200 sq. ft. per gallon over a smooth or primed substrate.

Mixing:

Part A is pigmented and should be uniform without lumps or hard settling. Examine Part B to determine that it is clear and has not solidified. This part can solidify by reacting with moisture from the atmosphere, keep containers tightly closed when not in use. Mix equal volumes of Parts A and B using a drill mixer. Scrape sides of container and mix with rest of material.

Pot Life:

A chemical reaction begins after parts A & B are mixed and this produces some heat. When the heat builds up in the container it accelerates the reaction and causes a rapid increase in viscosity. The time interval to reach a difficult to apply viscosity is the pot

at 60° F Pot Life is 2.7 hrs.

at 72° F Pot Life is 1.5 hrs.

at 85° F Pot Life is 1.0 hrs.

Cure:

Film cure rate is shortened with increasing temperature. At 72° F the set to touch time for the clear and White coating is 2.5 to 3 hours and 3.0 to 3.5 hours for the colors. The coating can be handled after 6 hours and take light foot traffic after 24 hours. Vehicular traffic can begin after 48 hours.

Thinning:

Do not thin product if application is by squeegee and roller. Use MEK (Methyl Ethyl Ketone) if needed for spray application and clean-up. Recoating:

Although the Liquid ProPoly® film reaches sufficient cure to handle or even walk on in less than 12 hours it requires approximately 7 days to reach full cure. Touch up or a second coat of Liquid ProPoly® may be applied within that period. If Liquid ProPoly® is more than 7 days old the surface of the film will have reached a cure condition that would prevent a second coat from adhering to it. In that event either abrade (sand) the first coat or apply one of the 1500 Series Proflex Primers® prior to recoating with Liquid ProPoly®

Useful Information:

You will have more time to distribute the material when the mixed product is discharged from the container onto substrate within 45 minutes. Addition of 10-15% solvent extends pot life.

When spraying always put pump suction tube into newly mixed pail and then add remainder of previous pail. Flush spray pump and hoses with MEK (Methyl Ethyl Ketone) solvent every two hours to prevent product from curing in the hose when spray application takes more than two hours to complete.

Do not apply Liquid ProPoly® if rain is forecast within 12 hours.
