Stain Block Elite is a state-of-the-art penetrating sealer that is equally effective on porous and dense surfaces such as concrete, natural stone and masonry. You can count on 5 Star Finishes for items for microcement and stone finishes such as penetrating sealer.    


  • Water-based, solvent free and low odor
  • Excellent penetration, long lasting

  • Interior and exterior use
  • Repels gas, oil and grease

  • No change to surface appearance
  • Silicone free, re-coatable

  • Easy application and fast drying
  • Water and stain resistant

  • 3-5% color densification

This is the one of only two water based sealers we have tested over the years that does not change the surface appearance of the plaster. Consistently this sealer has performed and seals well against water and general stains, especially for exteriors. Although this sealer is expensive, it will outperform any other sealer we have found on the Canadian market and is used on all our own jobs and has been for many years now.
We recommend this sealer for all light colors and specifically for our concrete effect grey plasters, as it produces the nicest overall appearance. If you are using our lime based plasters or concrete look white in darker shades please purchase our Stain Shield Penetrating Sealer. This Sealer can leave white residue on darker colors due to the high concentration of tint, and will discolor your finish. Using any other penetrating sealers that are lesser quality will only create even more damaging white stains. 

Stain Block Elite is a state of the art, water and stain resistant, penetrating fluoropolymer impregnating sealer. It has been specifically designed for porous to dense concrete, brick, natural and manufactured stone surfaces. When dry it is virtually invisible, leaving the surface with its original appearance and breathability. It resists oil and grease stains, rust stains, moss, mildew and spalling problems associated with freeze/thaw cycles. Stain Block Elite provides superior protection against moisture penetration, thereby reducing the formation of efflorescence.

Stain Block Elite chemically bonds with the silicates present in the surface, forming an insoluble barrier that will not fade, yellow, crack or peel. It is highly alkaline resistant and designed for use on dense surfaces such as: marble, granite, limestone, travertine, polished or tumbled stones, concrete, brick, pavers, slate, precast concrete, tile and manufactured and natural stone. It is easy to apply and fast drying. Commonly used in both commercial and residential applications, i.e.: dining, food preparation and serving areas.
