MAINTENANCE & CARE

Seal-Once & Poly Blend treated surfaces can be cleaned with 1 gallon of warm water, 14 oz. bleach, and 1 oz. of dawn dish detergent. Apply cleaning solution with a sprayer and allow to rest for twenty to thirty minutes before rinsing with water using a garden hose with a nozzle. Use cleaning solution to remove airborne mold and mildew stains, dirt, grime, etc. on the surface. Seal-Once & Poly Blend will prevent and resist any water, mold, and mildew penetration. Do not use oxidizers, corrosives, or strippers on Seal-Once treated surfaces.

Surfaces can be recoated with Seal-Once or Poly Blend at any time. Seal-Once or Poly Blend may need to be reapplied for fading tint color, surface damage, or in heavily worn or high traffic areas, or in places where the surface may have undergone noticeable changes. Apply the recommended cleaning solution above. Apply Seal-Once or PolyBlend either clear or tinted, two coats wet on damp with a brush, stain pad, or sprayer. When reapplying in small areas lightly overlap onto areas previously treated with Seal-Once or Poly Blend.
