Scofield - Revive Exterior Concrete Stain

Before applying stain, surfaces must be made porous and be dry and clean of all prior sealers, curing compound, oils, or other foreign materials that might
prevent penetration or adhesion, and meet a Concrete Surface Profile (CSP) of 1, as determined by the International Concrete Repair Institute, (ICRI), Alexandria, VA. Grind, acid etch, power wash, or scrub surfaces with stiff bristle brushes and strong detergents to remove these undesired materials and any loose concrete laitance that may harm adhesion.

Always rinse concrete surfaces and allow them to completely dry prior to application. Plan carefully and divide work areas into sections using walls, joint lines, or other stationary features to provide natural stopping points of the application.

Avoid unsightly lap marks by applying stain to full opacity at coverage rates described using a brush or acetone resistant sprayer.

Stir or shake containers at least every 5 minutes during application to ensure pigments are uniformly applied to the surface. Apply only when temperatures are between 40 °F (4 °C) and 95 °F (35 °C), and avoid application to surfaces heated above 95 °F (35 °C) from strong direct sunlight.

The preferred method of application is to saturate the surface to be stained with a pump sprayer, and work material into the substrate with a soft bristle broom until all liquid solvent has evaporated from the surface or penetrated into the substrate. Work the broom in random directions while moving from newly deposited wet areas back into the areas previously stained. Maintain a wet edge to the project to avoid lap marks. Do not allow material to dry while puddled.

If color residue remains after treatment has cured for one day, gently scrub and rinse with water to avoid tracking residual color to adjacent areas.

Do not thin. Coverage will depend upon method of application, surface porosity, and the texture of the substrate. Coverage on flat finished concrete is typically 100–300 ft2/gal (2.5-7.4 m2/L). Porous, broomed, or textured finishes will require more stain and coverages of 50 - 200 ft2/gal (1.2 - 4.9 m2/L) is typical.

Allow four to eight hours drying time before permitting foot traffic. Drying time will depend on temperature and surface porosity. Do not pressure wash or use aggressive cleaning methods for two weeks after application.

Clean tools and equipment with acetone, taking care to following the acetone manufacturer’s instructions and safety requirements.
