Frequently asked questions
-
What is this specifically for?
CompatibilityPolished porcelain tile and engineered quartz countertops/slabs - ultra-low absorption surfaces that standard impregnators can't penetrate. Nano-size molecules fill the micro-pores.
-
Coverage rate?
PerformanceVery high yield due to dense substrate: 1 quart covers 400-500 sq.ft. (~42-53 m² per litre) on a finished grouted install or quartz benchtop.
-
How is it applied?
InstallationApply with low-pressure hand sprayer or lambswool applicator. After 15-minute surface dwell, polish thoroughly with dry microfibre cloths. One coat on finished installs; two coats if applied before grouting.
-
Will it work on natural stone?
CompatibilityNo - this is specifically engineered for low-absorption surfaces. For natural stone, use Premium Impregnating Sealer, Dense Stone Sealer, or Color Enhancing instead.
-
Cure and warranty?
ComplianceAvoid moisture 6 hours; wait 12 hours before grouting; 24 hours for full cure / testing. 10-year performance warranty when applied by Accredited Applicator.
Why trade professionals choose Stain Proof
Stain Proof, also sold under the Dry Treat name, is a stone and masonry protection range built around impregnating sealers that soak into the surface instead of forming a film over it. The line covers solvent carried and waterborne sealers for natural stone, porcelain, quartz, pavers, concrete and grout, plus colour enhancing options and the acid, alkaline and daily cleaners used to prepare and maintain sealed surfaces. Supplied to the Australian trade through The Waterproofing Shop, including seal, clean and maintain packs that cover a whole job in one order.
