Do I need to prime my porcelain slabs?

Porcelain is an incredibly beautiful and hardwearing material that will do justice to any paving project you are contemplating.

However, it is a little bit different from other kinds of stone, and that means you should follow proven best practice when it comes to installation.

Why prime porcelain paving slabs?

Porcelain is durable for a reason. It is a non-porous stone, but that also means it doesn’t adhere to mortar as easily as other types of material.

While the process of installing your porcelain paving slabs may be similar to the one for sandstone, for example, you must add another stage to the process. That is using a primer for porcelain slabs.

This ensures the porcelain tiles adhere to the mortar and avoid popping up.

How do I apply a primer for porcelain slabs?

All you need to do to ensure your porcelain paving slabs are completely secure is to paint the reverse fully with slurry primer before you lay them.

This will bond the non-porous porcelain to the mortar base helping to maintain the structural integrity of your outdoor paving project. Without the bond of slurry primer, your porcelain paving will not adhere to the mortar bed and therefore not hold out well.

This may be an extra task to factor into your patio or other outdoor building project, but it isn’t excessively time-consuming and it doesn’t add much to the cost.

Which is the best slurry primer for porcelain paving?

First, it is important to understand that wet slurry primer needs to be adhered to a wet mortar bed so that when the mortar dries out, it sucks onto the slurry primer and slab and forms an extremely tight bond between the two.

There are two varieties of slurry primer that you can opt for:

  1. Self-mix slurry primer

The self-mix slurry primer is a dried powder that you mix with water. For this you might need a drill whisk or paddle whisk to ensure that it is combined into a smooth paste.

  1. Pre-mix slurry primer

This is a primer, which as the name suggests is ready mixed.

There is really no difference between the two types of slurry primer apart from the fact that self-mix is more time-consuming, while you will probably pay a little more for the pre-mix slurry primer.

There are many products on the market, but the best slurry primer for porcelain paving is UltraScape pro-prime slurry primer, which provides an excellent bond between bedding concretes and porcelain paving slabs.
