There are three types of sealer generally available for use with block paving, i.e. water based, solvent based acrylic and polyurethane sealer.

Water based sealers are emulsions which have very small particles dispersed in water. Whilst they will form a film on the surface, only a weak bonding is achieved. They are a slow curing product when cured at low temperatures and high humidity due to the dampness in the air. Water based Sealers have poor water resistance and may whiten when wet.

Solvent based acrylic sealers are one of the most popular choices of sealant to seal and protect block paving at home. They are relatively cheap to buy compared to polyurethane. Acrylic resins are a softer type of resins yet are still an excellent source at protecting block paving with a high gloss finish.

The most effective sealer for long term performance has been found to be polyurethane sealer. Polyurethane is largely used in the commercial market i.e petrol stations, due to having exceptional resistance to fuels and de-icing materials. It effectively seals and stabilises jointing with a single coat application. Additional coats will provide a gloss finish, if desired.
