Clean Your Space

Clean area of any loose caulking or silicone. Seal gaps, cracks, etc. with Liquid Rubber caulking (or equivalent). Power washing is recommended. Make sure area is thoroughly dried. Ensure fasteners are tight; replace if needed.

Contain The Mess

Keep all materials on a flat/level surface, on top of a tarp or piece of cardboard. Have a pail of soap and water, rags and mineral spirits ready in case there is a spill. If a spill happens, use rags to soak it up, cleaning immediately with soap and water. If it is dried, use a razor/scraper to remove. Use mineral spirits to weaken the material and remove with a wire brush or grinder.

Note: Use mineral spirits sparingly.

Prepare Your Space and Gather

Make sure your surface is totally clean, dry and free of all matter.

Detail Work

Bridge joints, seams, vents, skylights etc., with Seam Tape. Apply MetalSafe Sealant, Color Sealant, or Waterproof Sealant to fasteners, tight seams and vents.

Masking

Using painter’s tape, make sure your roof is properly taped to avoid seepage from the area to other parts of your structure.

Prime

For areas with rust, if your final coating is color, prime with two coats of Multi-Purpose Primer or a water based Rust Primer to prevent bleed through.

Tip From The Pros:

AVOID HOT, DIRECT SUNLIGHT DURING APPLICATION.

Apply Coating

Apply your selected Waterproof Sealant to entire roof. Apply the next heavy coat when the product is dry to the touch (4-8 hours) and nothing is wet underneath. Tacky is ok. Need curing time.

Clean Up

Remove tape while coating is still wet and close container to secure leftover product. If spillage occurs, soak up as much material as possible with rags. Clean immediately with soap and water. If spill is dried, scrape off as much as possible with a razor or scraper. Use mineral spirits to weaken product and an appropriate tool such as a wire brush or grinder to mechanically remove. If splashed on the skin immediately wash thoroughly with fresh water. If the product has dried on the skin massage the area with medical grade mineral oil, baby oil or edible oil, then wash with soap and water. If irritation persists seek medical attention.
