UREA-TUFF 6500-VT - Base Coat
UREA-TUFF 6500-VT is a two component, fast setting, rapid curing and solvent free Aliphatic Polyurea Elastomeric Coating. It is designed for vehicular decks as well as heavy duty pedestrian decks and roof decks. UREA-TUFF 6500-VT can be applied to properly prepared interior or exterior concrete, plywood and metal surfaces. It is suitable for application in temperatures as low as 32°F and is rather insensitive to moisture.General Information
Composition: Liquid applied, two-component, flexible, extremely low odor, hybrid polyurea elastomeric coating.
Basic Uses: For waterproofing parking decks, walking decks, roof decks, mechanical room floors, etc. Designed for vehicular and heavy duty pedestrian traffic.
Limitations: All surfaces must be completely free of foreign matter and primed with TUFF-POXY PRIMER #3. UREA-TUFF 6500-VT has a relatively short work life, so once it is mixed, the coating must be poured onto the surface and applied immediately.
Colors: Sidewalk Grey and Monterey Sand. Custom matched colors are available with minimum required quantities.
Sizes: Available in 4.5 gallon kits and 1.5 gallon units.Product Installation
Surface Preparation:All surfaces which are to receive UREA-TUFF 6500-VT shall be free of contamination such as water, curing compounds, hardeners, bond breakers, paint, etc. Power trowel followed by a light broom finish is recommended for concrete surfaces. It is desirable to watercure concrete in lieu of using curing compounds. The concrete surface must be thoroughly cleaned by shot-blasting, sand blasting or mechanical grinding followed by the thorough removal of any resulting residue.
Except for non-moving shrinkage cracks, all other cracks must be sealed with UREA-TUFF 6500-VT and taped with 4” TUFF-TAPE “PW” Polyester Reinforcing Fabric. All surfaces must be primed with TUFF-POXY PRIMER #3 prior to application of the coating system. Prime at a rate of 250-300 square feet per gallon.
Application: Lightly stir the A-Component (pigmented side) for 2-3 minutes using a Jiffy mixing blade to evenly distribute the pigments that may have settled to the bottom of the container. Then pour the “B” Component (clear side) into the “A” Component. Scrape the container to drain all the “B” Component into the “A” Component. Mix thoroughly using a Jiffy mixing blade attached to a low speed drill to a uniform color without any streaks. Mix for 2-3 minutes. Once mixed, immediately pour UREA-TUFF 6500-VT onto the surface of the substrate.
Use a notched squeegee to evenly apply the material, then backroll using a short nap roller to break air bubbles. NOTE: Higher temperatures will reduce the work life. UREA-TUFF 6500-VT shall be applied to the primed concrete at a rate of 67 square feet per gallon. Following a 4-8 hour cure time of the first coat, apply a second coat of the UREA-TUFF 6500-VT at the rate of 80 square feet per gallon and while coating is in a fluid condition, broadcast desired quantity of 16 mesh aggregate and backroll.
After a 4-8 hour cure, clean off any loose aggregate and apply a third coat of UREA-TUFF 6500-VT at a rate of 100 square feet per gallon. Broadcast 16 mesh aggregate and backroll. Allow 24 hours cure time (depending on ambient and substrate temperature) before allowing moderate traffic on the finished system.Maintenance
Since, as with all deck coatings, the topcoat is subject to staining by such foreign matter as nitrates, fertilizers, hard water, and other substances, it must be maintained. Please refer to the Maintenance Manual for proper maintenance procedures. The manufacturer is not liable for staining caused by hard water deposits, nitrates, fertilizers and other foreign matter.
If UREA-TUFF 6500-VT is damaged, it can be repaired by abrading the surface, cleaning the surface with acetone or xylene and recoating it with the UREA-TUFF 6500-VT coating.Warnings & Hazards
