Applications
Use on porous clay tile, concrete, masonry, slate, flamed granite, brick, pavers and other suitable porous stone when a visibly glossy coating is desired. For sand-joint stabilization on 12 × 12-inch pavers, the manufacturer gives a separate approximate rate of 100 sq ft per gallon.
Selection and Use
- Test an inconspicuous area before coating the whole installation. Higher porosity and additional coats affect product consumption and appearance.
- Prepare a clean, dry surface and avoid puddles. Neutralize acid-cleaned surfaces according to the manufacturer’s preparation directions.
- Do not use on ceramic, porcelain, polished marble or polished granite. Avoid application in hot midday sun or below 55°F.
- Store above 40°F and protect from freezing. Choose 646 Plus instead when a lower-gloss satin finish is wanted.
