Paving cleaners – manmade paving (bricks or concrete pavers)
HCl acid is the best substance to use when removing excess grout from brick or concrete pavers, and will leave a good clean finish.
To avoid damaging your clients’ plants or grass, try to wash into a drain and not onto garden beds or areas of lawn. Mix roughly ten parts water to one part acid (until the mixture fizzes) – always add the acid to the water, never do it the other way around.
And NEVER use it on natural stone pavers.
Paving cleaners – natural stone pavers
Once again, NEVER use HCl acid on natural stone pavers. Instead, use a specialised product to remove light mortar or grouting haze.
Miteq Masonry Cleaner 304 is safe to use on terracotta, natural stone and cement-based pavers and grouts. It is also great for removing the efflorescence (white bloom) you see on both terracotta and glazed pots. And while it won’t repair their cracks and chips, it will help give them a new lease on life by also cleaning off mould, mildew and dirt stains.
Miteq Masonry Cleaner 306 is particularly good at removing organic based stains (such as timber and rust stains) from clay bricks and pavers, terracotta, ceramic tiles, concrete, natural stone and cement-based pavers. It’s also really handy for cleaning the shower!
Miteq Masonry Cleaner 301 is the best thing to use when cleaning paved driveways that have accumulated grease and rubber marks and are generally soiled. It is also a great product for removing rubber marks and grease from terracotta, natural stone, cement based pavers and grouts. These surfaces all come up a treat, but especially so when it is used with a pressure washer.
Paving sealers are a great way of making sure that most soils, greases and general food stains don’t become ingrained. They keep stains from penetrating deeply, especially into newly laid surfaces, and make cleaning and the removal of contaminants much easier. There are two types: penetrating sealers and surface sealers.
The first type of penetrating sealer is water-based. This sits just below the surface and gives a good “natural” look – it doesn’t change the appearance of the paver – while also acting as a waterproofing agent. It allows the pavers to “breathe” and can be painted if needed. Miteq Sealer 102 is especially good around pools and other damp areas.
The second type of penetrating sealer is solvent-based, and is used to give a higher level of protection to dense surfaces (granite, bluestone etc) and in heavily trafficked areas (driveways, patios, bathrooms, etc). Miteq Sealer 103 is ideal for these surfaces and areas.
Surface sealers, such as Miteq sealer 201, are used to achieve a high-gloss “wet” look. They sit on the surface of the paver and don’t allow it to “breathe”. While generally glossy, they can have a matt finish. They can often be slippery, and so some varieties can have an anti-slip agent added to them. Some can also be used as an anti-graffiti protectant.
