Great Product
Would RecommendWhite painted Brick. Covered 1/8 to 1/2 gaps in mortar well. Super texture perfectly matched mortar. Held paint well. Flowed really well. Just the right consistency to flow but not run. So far no shrinkage overnight. Highly recommended product.
Dried out in tube. Eould not dispense.
