Oil Seal #330

Product Details

A latex-based primer designed to prime existing oil and grease spots prior to asphalt pavement sealcoating. HP #330 Oil Seal ensures adherence between existing asphalt and applied sealcoat while preventing oil, gas, and other petroleum-based substances from migrating through newly sealcoated asphalt pavement.

Surface areas to be treated must be free from dirt and dust. Scrape excessive build-up of oil, grease, or any other chemical stain spots. Lightly burn off excessive build-up.

Mix well before using. Use full strength on heavy oil spots. Reduce 1 to 1 or 1 to 2 with water, depending on the build-up of oil, grease, and other stains. Can be applied with a suitable spray machine, push broom, brush, or roller.

300-400 square feet per diluted gallon. Wash tools in water. Use a suitable paint thinner if the material has dried.

Keep from freezing. Do not store in direct sunlight or where temperatures exceed 100F. The container should be closed when not in use. Keep out of the reach of children.

Available in 5-gallon buckets and 55-gallon drums.
