FAQ's

Can I paint over Stucco Sealer at a later time?

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 any 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 any remainder in a temperature-controlled environment (meaning do not let freeze or overheat).
