Concrete sealer

So far so good, water runs off it and hopefully prolong its life.

Farley Calhoun (Stockton-on-Tees, GB)
Great product

My second time ordering from this company, first time was block paving Color sealer, this order was clear polyurethane sealer 4 years later, I guess that means the product’s are quality.

Thanks premium paints

Riekert Tracey (Montreal, CA)

Great product. Goes on easily and covers very well.

Ken Sykes (Manchester, GB)
Product is very good and easy to apply

I bought 20L of concrete sealer and applied 2 coats. It keeps the concrete dust under control and stops the dust being transferred into cars and the house carpets. Delivery was slower than I expected, took most of a week to arrive in Manchester. Product excellent.

S K (Reading, GB)
Great sealer, terrible delivery and courier tracker

The sealer went down really easy and was a great first part to painting the floor.
Unfortunately the delivery tracker doesn’t track, and I’m still waiting for another order which I paid to have delivered in 1-3 days…and it’s way past that.

Robin Chapman (London, GB)
Paintmaster - Concrete sealer - Polyurethane Resin Based

A dream to apply and did what it said on the tin!! Sealed the concrete and water sitting beaded on top like it should.

Ranjit Roy (Stockton-on-Tees, GB)
Concrete sealing

Painted faded black concrete patio with wicked concrete paint and then applied this, really good shiny finish, rained a few times since but after drying looks shiny again. Let's see how long it lasts.
