Masonry Flat Concentrated (for Dark Colors) must be diluted with clean water 20% - 30% prior to application. 

Masonry Flat is a high-performance Mineral Silicate coating, ideal for masonry surfaces such as brick, stone, stucco, concrete or Hardie Board. Masonry Flat chemically combines with the substrate so it will not blister or peel, resulting in a non-film forming, easy-to-apply, flat finish. Masonry Flat is a natural mineral product that is permeable/breathable, absorbs CO2, and provides good anchoring power with mineral surfaces through a process called silicatization (silica-lime solution reaction). It is odorless and Zero VOC and is formulated with a special binder, made from a special inorganic binder base on a mix of soluble, stabilized and purified silicates (D-SILICATE). The binders consolidated and strengthen the coated surface while decreasing the speed of absorption of liquid water maintaining its water vapor transpiration power.

  • Ideal for brick, stone, or stucco
  • Will not chip, peel or flake off
  • 20 Year warranty, if applied as directed
  • 2 coats, no additional primer for unpainted, absorbent masonry
  • Pressure wash and paint on the same day as masonry surfaces must be dampened
