Which is the best paving sealer for your Indian sandstone patio, porcelain paving or indoor surfaces? Read our quick rundown of the sealers we’ve found to be ideal for our products.
Dry Treat Stain-Proof Natural Stone and Porcelain Sealers
We carried out our own extensive tests of various sealants available and, in our experience, Dry Treat offers superior performance. Their formula impregnates the surface of the stone more deeply than other sealers and offers longer-lasting protection. For this reason, we always recommend Dry Treat products.
Some other benefits of Dry Treat paving sealers:
- Prevent/reduce efflorescence, as water carrying the minerals that cause efflorescence cannot get close to the surface.
- Prevent/reduce freeze/thaw spalling. The sealant repels moisture from above, but also prevents water seeping up from underneath, so protecting the surface of the stone.
- Reduce algae growth ingrained into the stone.
Dry Treat Stain-Proof Premium Impregnation Sealer
This is our most popular paving sealant. It’s formulated with molecules that migrate through the pores in the surface of the natural stone paving and find sites to bond to through a chemical reaction. It’s a gradual process over three to four weeks, with oil and water repellency increasing significantly as the treatment cures. Included in the formulation are modified silane molecules that are hundreds of times smaller than the best competitor fluorocarbon/siloxane stone sealers. It can, therefore, penetrate stone that others can’t, such as polished granite.
It is suitable for most natural stones, including limestone, and can be used for patios, swimming pool surrounds, floors, walls, garages, kitchens, showers and countertops.
It can be used indoors and out, and is applied in two coats (sometimes three on a highly porous surface) with a low-pressure hand spray, brush or similar. It is weatherproof within 8-10 hours and can be walked on 24 hours after application.
Minimum coverage is around 6-12m2 per litre, depending on the porosity of the stone, and it carries a 15-year warranty when applied by an accredited expert.
Average coverage rates
- Portland Limestone 5m2 per litre
- Sandstone 6m2 per litre
- Limestone 7m2 per litre
- Granite/Basalt 8m2 per litre
- Slate 12m2 per litre
Please note, these figures allow for the two coats required as part of the application process.
Dry Treat Stain Proof Porcelain and Quartz Sealer
This impregnating paving sealer, formerly known as Porcelain Plus, is specifically aimed at Porcelain and Quartz, with nano-sized molecules that can penetrate the micropores in the paving surface. It’s designed for dense paving with low absorption rates and offers long-lasting protection that will hold up to commercial cleaners and equipment. When applied it is invisible and doesn’t form a film, so it doesn’t interfere with surface friction.
It's suitable for all sorts of porcelain, including through body porcelains (such as our Italian ranges), textured porcelain, matte, glazed, multi-glazed, polished and semi-polished porcelains. It also protects grout joints.
Applied as a single coat to finished tiles and grout, it may also be used as a pre-sealer before grouting, to help remove excess grout. Minimum coverage is around 40m2, and may be more depending on the chosen paving. Applied by an accredited expert, it carries a 10-year warranty.
Dry Treat Stain Proof Colour Enhancing Sealer
This impregnating, colour-enhancing sealant, formerly known as Dry Treat Intensifia, is aimed at natural stone, brick and concrete. Colour enhancement is visible immediately. Maximum water and oil repellence is reached after around three weeks’ curing time.
Even outdoors under UV light, it offers long-lasting colour protection. Water and oil repellency will last five years, with a 5-year warranty when applied by an accredited applicator. The longevity of colour enhancement depends on material and location, and the paving sealer can be applied at any time to a cleaned surface, to re-enhance. Unlike with topical sealants, there is no need to strip back.
Coverage ranges from 4-12m2, depending on the paving material.
