It helps prevent the growth of mold and mildew, protects against stains, and is safe for indoor or outdoor use with little to no odor and zero VOC’s. Unlike conventional water repellents, Paint Sealer is available in concentrate form so you never have to spend extra money on water and excessive packaging.

What makes Paint Sealer different?

A proprietary ingredient called Micro-Lok™. This additive ensures the absorption of the sealer into the surface and creates a long-lasting hydrophobic barrier that is not affected by weathering, dirt, freezing temperatures, UV light, and wind-driven rain, among many other damaging elements.

Dry Time


Can I use this on an unpainted surface?

No. You will want to use the appropriate sealer for your surface which you can find here.

Can I paint over Paint Sealer at a later time?

Yes. You can paint over Paint Sealer but keep in mind it will not protect the new paint from moisture damage. You may want to use Paint Sealer after the surface is painted and fully dry to protect the new layer of paint from moisture damage.

How long do I wait after I paint my surface before I can apply Paint Sealer?

You will want to wait 3-4 days after painting before applying Paint Sealer on top.

What is freeze / thaw damage?

Freeze-thaw damage refers to the deterioration of materials, such as concrete, masonry, or brick, due to repeated cycles of freezing and thawing. When water penetrates into porous materials and freezes, it expands, causing internal pressure and damage. Subsequent thawing can lead to the formation of cracks, spalling, and weakening of the material.

What is the mix ratio for the concentrates?

For the quart concentrate that makes TWO gallons – Dilute 1 part concentrate to 7 parts clean water. Store the remainder in a temperature-controlled environment (meaning do not let freeze or overheat).

For the quart concentrate that makes FIVE gallons – Dilute 1 part concentrate to 19 parts clean water. Store the remainder in a temperature-controlled environment (meaning do not let freeze or overheat).
