EQUIPMENT NEEDED

Medium- to high-pressure airless sprayer equipped with a 24-inch wand and a .019 fan tip spray jet. (Note: when applying as a cure, use only medium pressure.)

HOW TO APPLY

Note: In hot climates, mist-wet the surface with water and remove any puddles prior to application.

1. Use medium- to high-pressure airless sprayer complete with a 24-inch wand and a .019 fan tip spray jet.

2. Hold spray tip 6 inches from surface.

3. Apply to the point of saturation at the rate of 200 sq. feet per gallon with an overlapping spray pattern of approximately 10% to 15%.

4. Do not puddle or buildup can occur, causing a darkening effect.

5. Begin applying at the lowest level elevation. For example, walls and slopes should be applied side to side, from the bottom up.

6. Use only on green or recently poured, clean concrete. DENSIFIER PLUS REPELLER will seal in any visible stains and will bring hidden contaminants to the surface while sealing them in.

7. Do not apply on frozen substrate or when temperature is near freezing.

8. Wait before applying paint, adhesives or other coatings at least 24 hours after sealing with DENSIFIER PLUS REPELLER.

9. Special note for concrete block: Block quality, cement content and porosity size can vary widely. Some may never be completely waterproofed and will only be dampproofed. Contact manufacturer for specific instructions.

10. DENSIFIER PLUS REPELLER may etch glass or dull shiny aluminum and can be difficult to remove from other surfaces once it dries. Cover surrounding surfaces or rinse immediately if sprayed with product.

11. DENSIFIER PLUS REPELLER is safe to use and environmentally friendly. We do recommend use of a painter's mask during application. Refer to MSDS.

HOW TO APPLY AS A CURE

1. Follow normal application instructions, except use a medium-pressure airless spray unit to avoid disturbing the top. For broom finished concrete that has not been allowed to harden, you may also use a non-atomizing spray apparatus such as a pump-tank sprayer.

2. Apply to the newly placed surface as soon as is practical following surface finish.

3. Apply at the rate of 150 to 200 square feet per gallon for broom finished concrete; 300 to 350 square feet per gallon on hard or steel troweled concrete.

4. Compatibility issues: If calcium chloride is believed to be in the concrete, any Densifier product would be likely to treat it as a contaminant and push it up out of the concrete, causing a whitening effect. There are also known compatibility issues with the Rheocrete admixture (corrosion inhibitor) manufactured by Master Builders, Inc. If either of these substances is used in the concrete, it is imperative that DENSIFIER PLUS REPELLER not be used as a cure. Use DENSIFIER instead and wait several weeks before applying the product so that this whitening does not occur.
