What Is Slurry Primer?

Slurry Primer is one product that sorts the professional landscapers from the amateurs. It’s a simple to apply product that ensures a really strong bond between pavers and the bedding mortar beneath them.  It’s also useful for wall copings, pier caps and even step treads. Using slurry primer is essential if you work is to comply with BS 7553

When you use a good quality slurry primer, you (and your clients) can be confident that their hard landscaping surface will stay put for at least their lifetime.  For you, that means no customer complaints and no slurs on your professional reputation.

In the days of yore, paving slabs were often substantially heavy pieces of natural stone whose sheer weight, added to the fact that they were rarely travelled on by anything heavier than a horse, helped to keep them in place.  Installation techniques from decades ago, were necessarily different to modern methods. And for good reason.

An old fashioned wet mortar bed works because it is partially absorbed by porous pavers and then, when it eventually dries, creates a seal between the two layers.  A bit like the sauce on one of Mrs Lambert’s steamed treacle puddings.

Modern pavers are a different beast altogether. They are relatively lighter, far less porous, and receive very different types and volumes of traffic to their ancestors. Which means that they need a very different installation technique. 

Slurry Primer is a polymer based product that creates a bond between low-porous slabs and the base layer beneath them.
