Pavers – Should you seal them?

You have just finished laying your new pavers. What’s next – should you then seal them?   That’s what we are going to answer today.  

Pavers can be made from concrete, clay brick and reconstituted and natural stone. Each of these materials has its own peculiar properties that need to be taken into account when deciding what material to use for any particular area of paving and what – if anything – to seal with.

One property that all pavers have in common is they tend to be porous. The more porous your pavers are, the more likely they are to absorb moisture and other liquids that might stain or contaminate the surface of the pavers.

Pavers that have absorbed moisture can be affected by problems such as:

  • Efflorescence
  • Mould growth
  • Water marks

Or they can be stained by:

  • Oils and greases falling from the barbeque
  • Wines and other alcoholic beverages (particularly red wine)
  • Coffee, soft drinks and fruit juices
  • Food especially greasy or juicy good
  • Gum Leaves

Sealing your pavers against water problems and staining is an important part of protecting your investment.   It makes cleaning of them much easier and faster and is considerably cheaper than the alternative.  Food and drink spills will wipe off and won’t penetrate and stain as quickly as an unsealed paver would have.   Sealing them also makes them far more resistant to moss or mildew growth.  It reduces the rate of colour fade and keeps them looking newer for longer.

We recommend sealing your pavers with a penetrating, water repellent or water and stain repellent sealers for best long term results.

Water repellent sealers protect against:efflorescence on concrete pavers

  • Efflorescence
  • Mould, Moss and Mildew
  • Tannin stains
  • Other water borne staining
  • General effects of weather

Water and stain repellent sealers protect against all the above as well as protecting against

  • Red wine and other alcoholic beverages
  • Oils and greases – e.g. from the BBQ
  • Coffee and fruit juices

We recommend Tech-Dry’s range of premium sealers.  Manufactured here in Australia they can be used to control water related problems and improve resistance to staining. They are cost effective and easy to apply.

Once dried, the sealants are invisible (except Protectaseal Enhancer), they do not change the texture of the paver surface and will not change the natural slip resistance of the pavers once cured.

Protectacrete is a water repellent sealer that can be used on all types of masonry including pavers. Protectacrete is available in either water borne or solvent borne versions. Generally, water based works best on more porous materials and solvent borne is better on the less porous products. See our blog on Sealer Choice for more detail.

Protectaseal is a water and stain repellent sealer that is also suited for use on all types of masonry. It is also available in water based or solvent based varieties. Choice of type is similar to Protectacrete. Refer to our blog on Sealer Choice for more detail.

Protectaseal is also available in a colour enhancing version (Protectaseal Enhancer) that will deepen the darker colours in the pavers giving them a “wet look” finish without being glossy or slippery. Protectaseal Enhancer looks very good on imported limestones and sandstones, granite and other variegated stones and on honed or sand blasted pavers.
