- Approximate Coverage
200 to 250 ft²/gal on dense surfaces. Porous surfaces may require more material. Do not exceed 300 ft²/gal.
- Clean Up
Clean tools and equipment with detergent and water immediately following use. Clean drips and overspray with water while still wet. Dried TAMMSWELD may require mechanical abrasion for removal.
- Directions For Use
Surface Preparation
The surface must be clean, dry and structurally sound. The substrate must also be free of all curing compounds, form release agents and any other contaminants, which may prevent the proper adhesion of TAMMSWELD. The preferred method of surface preparation is mechanical abrasion. For oil-contaminated surfaces, using steam cleaning in conjunction with a strong emulsifying detergent may be considered. Rinse thoroughly with potable water. Allow the concrete to dry before applying TAMMSWELD.
Application, Bonding Agent
Stir TAMMSWELD thoroughly before use. Do not dilute. For hand application, wet brushes or rollers before use and shake out excess water. For larger areas or faster application, use airless spray equipment with 0.015 in. to 0.020 in. (0.38 to 0.51 mm) orifice size spray tips. Hold spray gun 12 to 18 inches (30 to 46 cm) from the surface and apply TAMMSWELD using a cross coat technique consisting of a horizontal pass followed by a vertical pass. Extremely porous surfaces may require two coats of TAMMSWELD.
Allow the TAMMSWELD to dry before placing repair mortars, concrete, or toppings. TAMMSWELD will dry in approximately one hour depending on the temperature and humidity. If more than 7 days pass between TAMMSWELD application and placement of the concrete, topping, or mortar, check several areas to ensure adequate adhesion. Make test applications on questionable surfaces.
Application, Polymer Modifier
When using TAMMSWELD to produce a polymer modified mortar, add approximately 3 gals (11.36 L) of TAMMSWELD per 100 lbs (45.4 kg) of cement content in the mortar material. The properties achieved by using TAMMSWELD as a polymer modifier will vary depending on the composition of the mortar, and a thorough evaluation of properties should be completed before using the polymer-modified mix.
