Frequently Asked Questions

Aqua Shield HD is a penetrating sealer based on the latest fluoro-bond nano technology, engineered for all types of surfaces. It penetrates into the pores of the surface rather than sitting on top, so once cured it won't alter the appearance of your tile or paving. It protects against water and oil-based stains by chemically reacting with the surface pores, creating a long-lasting, breathable protective barrier that also makes regular cleaning much easier.

Topical sealers form a physical barrier over the surface, which can create a darkening, yellowing or glossy effect. Surface (topical) sealers usually don't last long, can make floors slippery, and need to be completely removed the next time sealing is required. Salts and efflorescence may also build up under the non-breathable surface, causing the coating to appear cloudy.

Building materials such as natural stone, brick, concrete, tiles and grout are made up of countless invisible capillary pores. This makes them porous and allows them to absorb damaging liquids such as water, water-borne salts and oils, which cause premature deterioration — weathering, loss of strength, efflorescence, salt attack and unsightly staining. Sealing can eliminate or significantly reduce most of these problems.

Yes. Aqua Shield HD will not damage any stone, tile or grout surface and is specifically designed for highly polished surfaces as well as denser surfaces such as granite, marble and bluestone.

Yes — that's another major advantage of Aqua Shield HD. One flood coat is all that's required, unlike many other sealers which need at least two.

Try the water test. Place a tablespoon of water on the surface for 20 minutes, then remove it with a cloth, pressing hard to soak up any water in the texture. If the water is absorbed or leaves a dark mark, the surface needs sealing; if not, it's adequately sealed.

If you have sealed with Aqua Shield HD and maintained your surfaces properly, the sealer should last up to 15 years. Longevity varies with the type of stone, tile or grout, the location and the wear the surface is exposed to.

Clean weekly using a pH-neutral cleaner to remove dirt and grime. Strong acidic or alkaline detergents may affect the sealer; mild, pH-neutral products are strongly recommended.

No. Aqua Shield HD doesn't change the slipperiness of the surface, and doesn't cause any darkening, yellowing or visible shine. It's also ideal around swimming pools and other wet areas.

Three main factors set penetrating sealers apart: the carrier, the expected lifetime of the sealer, and the depth of penetration below the surface. A good depth of penetration provides longer-lasting protection against traffic wear and weathering.

No. Aqua Shield HD penetrates and bonds to the pore structure of your surface. It is not a surface coating and will not crack, peel, yellow or discolour at any time.

Water and solvent are only carriers for the active ingredients; once applied, the carrier evaporates and only the active ingredients remain. You should always avoid solvents because of the health and environmental risks. Water-based sealers are easier to apply and contain no toxic chemicals.

All Aqua Shield HD products are non-toxic and safe for use in food-preparation areas.

Since penetrating sealers don't completely fill the surface pores, marks from things like rubber-soled shoes can still discolour the surface. These are surface marks and can usually be cleaned away.
