SCOFIELD® Repello® FPS is a proprietary blend of inorganic fluorinated polysiloxane polymers designed to deeply penetrate porous cementitious surfaces and render them water repellent and stain resistant. It is barely perceptible when dry, breathable, will not crack or peel, and penetrates to leave surfaces resistant to staining from oils, sugar, and common foods. It is suitable for use on flat, angled, and vertical surfaces.
