Acrylic Film-formers vs SiF Penetrating

SiF Sealers Will

SiF Sealers Will Not

Sealers are formulated with proprietary additives enabling application to wet substrates
  • No loss in adhesion
  • No loss in stain resistance performance

Coverage & Substrate Porosity

Coverage rates will depend on substrate porosity and can vary from 2-25 m2/L. The table details the recommeneded products for the given typical substrate porosity. Penetration into very dense substrates are best achieved with solvent based sealers. Water based sealers will also penetrate but usually to a shallower depth.

Important Note :

  • Don’t apply if pools of water present

  • Don’t apply to hot surfaces (>30oC), mist with water to cool

  • Don’t allow sealer to pool, remove excess

  • Avoid contacting surfaces not meant to being sealed

  • Don’t apply if rain expected in at least 24 hours
