BEST VALUE FOR EXTERIOR STONE PROTECTION!
A silane/siloxane base impregnator of excellent stability against alkali, infiltration of dirt and water, frost damage, and efflorescence for all interior and exterior natural and cast stone. HMK® S31 is an invisible below surface seal, with 100% vapor permeability which leaves a natural appearance.
HMK S31 is a Permanent Impregnating Sealer. Once applied, you will NOT be able to remove it or use other types of sealers.
Note: Do not allow S31 to dry on surface since cured S31 may need mechanical removal.
SUGGESTION: Prepare Surface for Sealer using R55 Intensive Cleaner.
Apply to chemically clean and dry surface with natural bristle brush, Sealer Applicator Sponge, or HMK® ZI70-171 Sealing Brushes for larger areas. One or two thin and even applications wet on wet are usually sufficient. Allow 5-10 minutes between each application for penetration. Repeat process for more absorbent surfaces. Thoroughly remove excess S31 5-10 minutes after last application with Premium Microfiber Wiping Cloth or white terry cloth; add solvent if necessary to facilitate the excess removal.
Protect from water/rain for the first 3 days curing time. S31 may require up to 28 days to fully cure under very dry air conditions. A humid, but not wet, climate helps and expedites the curing process. Do not apply S31 with temperatures above 85 F or below 50 F.
