It was perfect for the job, thank you for your help when I first inquired about the sealer.

By Paul Dodd

Really easy to apply sealer with a roller and dried quickly. Seems to be working - the water and dirt no longer soak into the concrete slab.

Really great product. Used for a DIY concrete kitchen worktop and it was perfect as it is food safe which is very hard to find in the UK. No fumes at all and very easy application. Didn't change the appearance of the concrete at all but there is no more dust / erosion of the surface. Couldn't have been easier or better for the purpose. Well worth the money. Customer service was fantasic too, they were very helpful over the phone and delivery was quick and efficient

Best Concrete Sealer for Floors & Walls

Protective concrete sealer for walls, floors and concrete worktops. The product is Food Safe.

Our Premium concrete sealer offers enhanced protection to concrete surfaces. It is very effective as a concrete floor sealer and provides increased stain resistance from oil stains and other surface contaminants. Premium concrete sealer is a clear concrete sealer that once cured will not alter the appearance of the surface it has been applied to.

Our high quality premium concrete sealer changes the chemical structure of porous concrete substrates. This creates an oil, stain and water resistant membrane. Application of the sealer will not change the appearance of the concrete and importantly remains moisture vapour permeable.

Our Premium Concrete Sealer is specified by architects and surveyors for concrete sealing applications to all types of commercial and industrial projects.

Once dry, the superior concrete sealer not change the appearance of the concrete.
