  • ± 50% for P795 PREMIUM and H725 FACADE

Can I use Seal 'N' Flex® on natural stone substrates?

Yes, these are non-staining sealants, suitable for natural stone. As natural stone is a natural product however, it’s impossible for us to test everything. It's therefore good practice to test a small area first to confirm suitability.

Can Seal 'N' Flex® be fully submersed in water and swimming pools?

They can sit outside in the wet no problem, but cannot be left permanently submerged.

What is the difference between P795 Seal 'N' Flex® PREMIUM & P590 Seal 'N' Flex® ONE PLUS?

The main difference is the modulus. P795 is high modulus, making it ideal for floor joints. As a low modulus product, P590 is best for high movement joints like precast concrete panels, natural stone facades, ACM and so on. 

Do I need to use a primer? 

Seal N' Flex® can be applied to the most common building substrates without the use of a primer; please check the TDS before using. 

What colours are available?

Initially - black, grey and white
