I paid a builder £500 to apply Thompson water seal to one wall of my garage. it did not work. he returned and saw the flooded garage floor, and wet walls. He asked if I would like him to do the job again. Surprisingly, I said " yes". He purchased another tine, and had two of his men apply another two coats.
Utter waste of money. The garage walls are still wet, and the floor is saturated!! Dreadful.

Did not work on my wooden clad summerhouse. I contacted Thompson and received an amazing reply from their customer service agent..."not recommended for wood, suitable for brick, plaster & concrete".....this is NOT what it says on the tin. There has been dialogue with the company, but as the conversation progressed, the message was the product is fine (including for wood), and I am responsible for the failed result.
This stuff may be fantastic for brick, plaster and concrete (I don't know), but I do know it should be avoided for wood treatment.

Their products used to be good but recently bought 5litres of stone sealant and it’s like water. Useless. Can’t get Thompson to reply to my email. Avoid.

Awful company and awful products! Whatever you do do not use One-Coat Patio & Block Paving Seal on Indian sandstone as my 6 month old patio now looks ruined! it looked nice for about a month after applying but the finish now looks terrible, I've emailed Thompsons 3 times over the last couple of months asking what I'm supposed to do? and have not recieved one single reply. Disgusting service. I wish I'd Read all the 1 star reviews on screwfix before using this stuff.

asked customer support a simple question twice but they didn't bother to respond.
