Concrete Sealing For Decorative Concrete

Concrete Sealing For Maintenance or a Budget Makeover

Clear & colour concrete sealing requires correct preparation prior to resealing to prevent flaking and peeling.Clear & colour concrete sealing is an inexpensive way to add a bit of colour or protection to decorative concrete but ideally, you’d never do this on plain flat concrete because spray on paving, even just a plain one colour finish, is infinitely better.

But when you have stamped concrete as shown in these pictures, resealing is the most practical solution. If the stamped concrete hasn’t much original sealer left on it and is therefore quite porous, you could spray pave it but grinding back sealed stamped concrete is not practical due to cost.

That’s because the surface, not being flat, is not easy to grind efficiently, and I would never recommend the use of any paint stripper for environmental reasons so therefore, colour concrete sealing of stamped concrete is generally the best option.

The same rules apply to slate impression concrete for concrete sealing except clear sealer is mostly used here. Colour sealer is usually a mid gloss and clear sealers can be matt, semi gloss or wet look high gloss.

Concrete sealing stamped concrete that's very old and tired looking will bring it back to like new again.

Concrete Sealing of Existing Spray On Paving For a Freshen Up

How often does concrete sealing of existing spray on paving need to be done? It all depends on the extent of the wear and tear. Although manufacturers suggest resealing every 12 to 18 months or so, that’s mainly because they’re trying to sell more concrete sealer.

But you’ll know yourself when the concrete is in need of a clean and reseal and this might be many years if the concrete has only seen light traffic. Some areas subject to heavy traffic will need resealing more often than lightly trafficked areas so it’s really job specific.

Some people never reseal their spray on paving which won’t cause any damage but if it’s eventually resealed, you’d be surprised at how good it scrubs up with a fresh coat of concrete sealer so it’s never too late.

But concrete’s no different to anything else in that when it’s maintained, it will look better than concrete that isn’t looked after. As long as serious stains like oil etc are removed quickly before they get a chance to become permanent stains, your concrete will remain good.

Polyurethane

For harder and longer lasting concrete sealing, polyurethane can be used in place of conventional concrete sealing products. These are an excellent choice for garage floors as well as commercial areas subjected to heavy traffic. And polyurethane will also look great, providing a classy high gloss finish.

Penetrating Sealers For Natural Looking Pavers

Conventional concrete sealing leaves a surface coating on top but penetrating concrete sealers completely soak in and don’t alter the surface appearance at all so you wouldn’t even know if the surface has been sealed by looking at it.

What’s the point of that you may ask? Well, the main purpose of this form of concrete sealing is for protection against staining and the ingress of dirt and that’s what a penetrating concrete sealer will do.

Surface concrete sealing is not what you’d want to do on natural stone or terracotta pavers and sometimes on concrete pavers as well. That’s because natural pavers are there to look natural so by applying a penetrating sealer you will achieve the required stain and moisture protection but without affecting the appearance.
