    Simple to use and does not block up the spray head.

    Sealed Newly Laid Block Paved Driveway

    Had driveway recently blocked paved and cost didn't include sealing so decided to do it myself - found Everest Polyurethane Sealant on google search through Premium Paints at a good price as I needed 4 x 20ltrs to cover 140sqmtrs with 2 coats (that didn't quite complete 2 coats -could have done with another 5ltrs). Staff were very prompt in answering any queries and dispatch/delivery was within days. Results were very satisfying, have recommended to neighbours who asked whilst passing by - will be using again in a few years time.

    Floor Paint - Brilliant!!

    This is the second time I have ordered from this company, and their service is excellent. The product itself is the best we have used on our factory floor, and we have tried a couple of different ones over the years. Its coverage is good and its hard wearing, we are running pallet truacks and fork lifts over it!!

    Overall, very happy

    Great product would highly recommend.

    Goes on well and seals the concrete so no more dust and grit coming into the house. Thanks xx
