Surface Preparation
All surfaces must be 14°F or above and free from ice or water. Concrete to be treated must be at least four weeks old, completely dry and free of contaminants. Grease or oil should be removed with Watco Bio-D (or a similar emulsifying degreasant) and the area thoroughly washed off and allowed to dry. Very smooth concrete or concrete with surface laitance (a weak dusty layer) should be abraded or etched with Watco Cemtetch to ensure adequate adhesion. The concrete should be thoroughly washed down and allowed to dry after treatment with Watco Cemtetch. Previously painted surfaces should be thoroughly abraded by sanding to improve adhesion and to remove any weak or loose material. A trial area is advisable to test compatibility with previous coatings. Below 40°F it may be necessary to avoid processes which involve wetting the floor due to the difficulty in drying. A good sweep or mechanical brushing may be sufficient. Do not apply outside if rainfall is imminent.

Mixing
Mix between 15°F and 75°F. Remove the two inner tins from the tall outer tin. Stir each tin thoroughly and pour all of the contents into the outer tin (scrape around the inside of the tins to remove any residue). Mix the components together thoroughly using a spatula or a similar wide bladed tool (a piece of wooden batten is ideal). Continue mixing until an even color and consistency are obtained. Do not mix more than one pack at a time. If a paint stirrer fitted to an electric drill is used, also use the spatula to blend in any unmixed material from the sides and bottom of the tin. Do not dilute. Pot life is 25-30 minutes at 60°F

Application
If appearance is critical we recommend the application of a small trial area first.

Apply between 15°F and 85°F. The viscosity will be somewhat thicker at very low temperatures, reducing coverage a little.
