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.

Stain Proof FAQs
Common questions about the Stain Proof range.
Still have questions?
Talk to our team for advice on the right Stain Proof product for your job.
What is an impregnating sealer, and how is it different from a topical sealer?
An impregnating sealer soaks into the pores of the stone, tile or concrete and lines them with a water and oil repellent rather than leaving a film on top. A topical sealer does the opposite: it coats the surface, changes the finish, and can wear, peel or trap moisture underneath. Most of this range works as an impregnator, including STAIN PROOF Premium Impregnating Sealer Dry Treat, so the surface stays breathable and looks close to untreated. Spills bead up and sit long enough to be wiped away before they soak in.
Are Stain Proof sealers water based or solvent based?
Both are stocked. The water based options are named as such, including Drytreat Waterborne Impregnating Sealer, Drytreat Waterbased Penetrating Sealer and Drytreat Waterborne Dense Stone, and they are usually chosen for interior work or anywhere solvent odour and ventilation are a problem. Where the product name does not say waterborne or waterbased, check the carrier on the label before you order, because it affects ventilation, clean up and site handling. If you are not sure which version suits the job, call the team before ordering.
Is a Stain Proof sealer the same thing as a waterproofing membrane?
No. These sealers repel water and oil at the surface so stains can be wiped off, but they are not a substitute for a waterproofing membrane in a wet area, on a balcony or under tiles. In Australia that work sits under standards such as AS 3740 for internal domestic wet areas and AS 4654 for external above ground waterproofing, and it needs a membrane system specified for the application. Waterproof first with the correct membrane, then seal the finished stone or tile for stain protection.
Which product suits porcelain, quartz or dense stone?
Polished porcelain and engineered quartz have very tight pores, so they need a sealer designed to penetrate that kind of surface, and STAIN-PROOF Porcelain & Quartz Sealer is the option in the range aimed at them. For dense natural stone such as granite and some marbles, Drytreat Dense Stone Impregnating Sealer and Drytreat Waterborne Dense Stone are the matched products. Suitability and spread vary a lot with the substrate, so check the technical data sheet for the product you are considering and always test on an offcut or a hidden area first.
Will sealing change the colour of my stone or pavers?
The standard impregnating sealers in the range are designed to be invisible and leave the surface looking much as it did before. If you want a richer, wet look instead, STAIN PROOF Colour Enhancing Sealer By Dry Treat and STAIN-PROOF Paver Enhancing Sealer are formulated to deepen the natural colour. How much darker it goes depends entirely on the stone, so do a test patch in an inconspicuous spot and let it dry fully before committing to the whole area.
How do I clean and maintain a surface once it has been sealed?
Match the cleaner to the problem. DryTreat Acid Cleaner is used for mineral deposits and grout haze on acid tolerant surfaces, DryTreat Alkaline Cleaner for oils and general build up, and Drytreat SMC Peroxide Cleaner for organic marks. For everyday upkeep, Drytreat Stain-Proof Daily Floor Cleaner and Drytreat Daily Countertop Cleaner are the day to day products, rather than harsh supermarket cleaners that shorten the life of a sealer. Never put an acid cleaner on marble, limestone or travertine.
Where can I buy the Stain Proof range in Australia?
The Waterproofing Shop stocks the Stain Proof and Dry Treat range online and ships Australia wide, covering the premium and waterborne impregnating sealers, the colour and paver enhancing sealers, STAIN-PROOF 40SK, the acid, alkaline, peroxide and daily cleaners, and the Drytreat Stone and Masonry Applicator for laying the sealer down evenly. If you would rather buy the whole job in one hit, the STAIN-PROOF Power Pack bundles sealing, cleaning and maintenance products together and comes in small, medium and large. Trade customers can call the team to confirm the right sealer for a given substrate before placing the order.
