READ ALL DIRECTIONS AND PRECAUTIONS BEFORE BEGINNING.

Surface Preparation: The success of a coating for concrete is always dependent on the proper surface preparation of the concrete. The following steps will help you reach maximum results and longevity.

Always start with a clean, dry surface: Concrete surfaces must be free of dirt, wax, grease, oil and other contaminants. Clean grease and oil with Mason's Select Concrete Cleaner and rinse thoroughly. New concrete must cure for at least 30 days prior to application. New or old, concrete must be dry prior to application. To test for moisture tape an 18"x18" polyethylene sheet approximately 4 mils thick over the concrete. Leave in place for 16 hours. If there is no moisture accumulated on the sheet you may proceed; if there is moisture, then allow concrete to dry for several days and retest.

Always start with a rough surface: Use Mason's Select Safe Solution for etching (or roughening) concrete. Safe Solution is non-corrosive, biodegradable, and easy to use. It will roughen smooth concrete and prepare the surface for staining. Simply apply Safe Solution, let it work for approximately 30 minutes, scrub and rinse well with water. After etching is completed, surface must be neutralized using Mason's Select Concrete Cleaner. Follow Concrete Cleaner instructions for neutralizing concrete surfaces. Because stains must penetrate to adhere, avoid surfaces that have been previously coated, have been treated with a release or curing agent (e.g., "tilt-up" structures), or other contaminants. Test bare concrete surface for absorption by sprinkling with water. Bare concrete surfaces that are especially smooth, non-porous or do not readily absorb water must be etched. Etching smooth concrete will allow coatings to penetrate and adhere to the concrete. Coatings can peel or be rapidly worn away from smooth concrete.  It is imperative to the performance of coatings that the surface be coarse enough to allow penetration and adhesion. Concrete surfaces must be rough to the touch or have a texture as rough as 120 grit sandpaper. Concrete may be etched (roughened/profiled) using Safe Solution or a floor grinder or shot blaster. 

profiling or etching the concrete prior to staining is highly recommended for maximum product performance.

Product preparation: Stir thoroughly from bottom to top of container and occasionally during application. Do Not Shake. Shaking will create excessive air in product. If shaken, allow air to escape product before application.

Thinning: None required.

Application: Apply product when the temperature is above 50ºF. and below 90ºF. Do not apply in extreme heat of day or in direct hot sunlight. Concrete must be cool enough to allow full product penetration. Do not apply if rain is likely to occur within 24 hours. Cover all plants, grass, vegetation, or nearby areas not to be coated. Keep container tightly closed when not in use.

Application method: Apply with brush, roller, pad applicator or pump-up type sprayer. When spraying, adjust nozzle to the widest possible spray pattern. Spray sealer with a broad sweeping motion until it begins to "wet up" (get wet) on the surface. Do not allow product to pool or puddle on the surface. One coat is all that is necessary using this application method. For added protection, a second coat may be applied after the first coat has dried for 4 hours. The second coat can be applied by brush, roller, pad applicator or pump-up type sprayer. If using a pump-up type sprayer, the second coat must be spread out to a smooth, even finish using a brush, roller, or pad applicator.

Coverage: 150-250 sq. ft. per gallon depending on porosity of surface. If a second coat is desired, spread rate of the second coat will be approximately 250-350 sq. ft. per gallon.

Dry time: 1 hour to touch, 4 hours to re-coat. Allow 24 hours for foot traffic and 72 hours for vehicles/furniture. Dry time can be affected by temperature and humidity
