It’s a crime not to prime

Priming is an important part of any paving installation but is something that is often overlooked. Neglecting to include a primer, such as UltraScape pro-prime slurry primer, can have disastrous consequences for your project and as a result the reputation of your business.

Traditionally, paving elements would be laid directly onto the bedding mortar, but due to ever-increasing traffic loading, street cleaning and general  wear and tear, paving often breaks away from the mortar, resulting in many high profile, costly failures and associated litigation.

The weather also plays a significant role in the destruction of paving. However, the additional bond a primer provides will help protect your paving from damage and de-bonding caused by the cold, heat, wet and freezing weather conditions.

The addition of a priming layer between the paving element and bedding mortar, yields an extremely high bond strength which prevents these types of failure, increasing the life expectancy of your paving and reducing ongoing maintenance costs.

British Standard 7533 was modified to reflect this change and now states all paving installations should have a bond strength greater than 2N/mm², double the previous requirement. This can only be achieved by using a priming agent such as UltraScape pro-prime.

UltraScape pro-prime is a slurry primer manufactured to meet the demanding requirements of BS 7533. Suitable for use with all paving types including stone and porcelain pavers, UltraScape pro-prime is simple to use and is proven to increase adhesion, preventing failure and prolonging the life of your project.
