Product Overview
Technical & Application Details

What is Blocseal Ultra - Overview?

Blocseal Ultra is a range of high performance polyurethane resin based block paving sealers that are designed for the commercial market as they have exceptional durability. Blocseal Ultra is long lasting, enhances and protects the block's surface, bonds the sand joints and inhibits weed growth. It is available in two different finishes - matt or gloss.

Where can Blocseal Ultra be used?

Blocseal Ultra is perfect for large commercial projects consisting of petrol station forecourts, leisure centres and town centres. It is used to protect, enhance and rejuvenate the block's surface, as a joint stabiliser, to restrict weed growth and prevent staining through fuel or oil spills. 


Blocseal Ultra cannot be spray applied, roller or brush application is more suitable. It is applied at an approximate thickness of 0.2mm per coat, therefore a 20kg drum will typically cover 100m². We strongly recommend that two coats are applied ensuring that the first coat is dry before the second coat can commence, allow roughly 2 hours at 20°C for curing.

Look at the Blocseal Data Sheet for full application information.


Blocseal Ultra is based upon moisture-curing polyurethane resin technology giving exceptional performance. It is an effective sealer that is highly durable, and long lasting.
