Slate

Care & Maintenance

Clean slate regularly with warm water or warm water with a neutral ph balanced cleaner. If you use a cleaner follow directions on the cleaner. Be sure to rinse with clean water so a film does not build up on the surface.

Raw slate has several options of sealers:

Matte: natural look

Stonetech Exterior Sealer: apply to small areas at a time. Brush on, do not allow to dry on surface, buff off in 3-5 minutes. Raw slate that has not yet been sealed will typically take 2-4 coats. The first coat will absorb quickly into the slate. Resealing will typically be every 3-5 years depending on traffic and will typically take 2 coats.

Matte: color enhanced look

Stonetech Enhancer Pro: apply to small areas at a time. Brush on, do not allow to dry on surface, buff off in 3-5 minutes. Raw slate that has not yet been sealed will typically take 2-4 coats. The first coat will absorb quickly into the slate. Resealing will typically be every 3-5 years depending on traffic and will typically take 2 coats.

Satin: color enhanced look

Slate Sealer: apply to surface allow to dry on surface. Apply in thin coats do not allow to “puddle”. Raw slate will typically take 3-4 coats and the finish will gain more luster which each additional coat. This sealer should be reapplied every 1-2 years depending on traffic. Not recommended in wet areas.

Gloss: color enhanced look

Lacquer Sealer: apply to surface allow to dry on surface. Apply in thin coats do not allow to “puddle”. Raw slate will typically take 3-4 coats and the finish will gain more luster which each additional coat. This sealer should be reapplied every 1-2 years depending on traffic. Wet areas need to be sealed every 6 months to eliminate any breach in the sealer which could result in efflorescence.

Test Area

Always test an area prior to doing entire area when cleaning and sealing raw slate.

Test the area to see if it needs to be resealed by applying a few drops of water; if the water stays in a ball and does not absorb into the surface the sealer is working. If the drops spread out and darken the surface (absorb) then the slate needs to be resealed.
