What Surface Preparation is needed before applying NANO + POLY?

Concrete Masonry Cleaner by Seal-OnceAll surfaces should be cleaned before sealing for best penetration and performance. Remove all old coatings, dust, debris and loose material. Remove oil, grease, algae, grime, mold and mildew stains with appropriate cleaners. LogFinish.com recommends Concrete / Masonry Cleaner by Seal-Once.

After cleaning, test absorbency of surface by sprinkling a few drops of water on the surface. If the water does not readily penetrate the surface, stripping will be necessary to remove old coatings prior to applying SEAL-ONCE NANO + POLY Concrete and Masonry Sealer. Retest surface when dry.

How do you apply Seal-Once NANO + POLY?

Do not apply in rain or when rain is expected within 24-48 hours.

DO NOT THIN. Mix well. Stir contents or shake thoroughly prior to use.

Test a small area to ensure acceptable appearance and penetration.

Apply first coat with a synthetic brush; pump-up garden sprayer; air-assisted; and/or airless sprayer. Use 15-17 tip and medium to coarse spray pattern. When spraying, always back brush for best results.

Second coat can be applied once first coat has penetrated but is still damp. Second coat must be applied within one hour of applying first coat.

For best results, apply in the shade and out of direct sunlight.

Apply to all surfaces. Do not use with other waterproofing products.

On very porous concrete or masonry, a third coat may be necessary.

Allow 3-4 hours for surface to dry completely before permitting light foot traffic.

What coverage should I expect with Seal-Once NANO + POLY?

Approximate coverage: 250-350 sq. ft./gallon per coat. Actual coverage will vary due to porosity of surface. Seal Once NANO + POLY is a two Coat Product!
