Why is Primer so Important for Paving Slabs?

Many Landscapers will use Paving Primer on Porcelain Paving tiles in particular, and some will use it on natural stone paving such as Sandstone Paving and Limestone Paving, as well as Cobble Setts and Block Paving. 

We would strongly recommend using Premprime Paving Primer on Porcelain Paving due to their manufactured properties and the lack of 'grip' that these smooth, porcelain tiles typically have. 

By priming your Porcelain Paving slabs before you lay them onto your mortar bed, you are providing an agent that will firmly bond the paving slabs to the mortar bed in a way that is sustainable through all weather conditions, along with the footfall your garden patio will experience. 

If you don't use a Paving Primer on Porcelain Paving, over time you will notice some movement of your patio slabs and they will essentially 'un-stick' from the mortar bed, which will cause problems down the line which will be hard to rectify.

Whether you're a landscaping professional or an experienced gardener taking on the challenge of laying paving slabs, you'll need to ensure you're using a top quality Paving Primer, especially on Porcelain Paving Slabs.

Precautions: This products requires careful handling; we recommend wearing protective gloves and clothing. As this product contains cement which is highly alkaline, skin irritation may occur when in contact. If this product gets into your eyes, wash out immediately with clean water and seek medical attention if irritation persists. This should be used in a well-ventilated area and mixed carefully to avoid too must dust rising.   

Step 1 - Preparation

Once you have prepared your mortar base - tips on Laying Paving Slabs can be found here - you should be ready to start priming your paving slabs. Ensure the patio slabs have been cleaned of any dust or debris by simply brushing down or washing with clean water. Ensure you have carried this out for your entire batch of paving slabs before you start priming. 

Step 2 - Mixing

Pour 5.95 litres of clean water into a large container. Add UltraScape prem-prime powder slowly and mix for 3 to 5 minutes to create a smooth, lump-free slurry. Your Primer is now ready to use.

Step 3 - Priming

Start to apply your paving primer liberally by using a small paint roller and aim to coat the back of the paving slab with 1-2mm of the primer. Once you're happy that the entire surface area is coated with primer, immediately place your paving slab in place onto the prepared mortar bed. Repeat this process across your paving tiles. 

Step 4 - Storage 

If you have any of this powdered substance left, you can store this back in its tub, provided there is no water present. You can store this for up to 8 months in a cool, dry place.
