The RSLTWSU5L Thompson's One Coat Water Seal Ultra protects against water damage in one coat. The silicone micro emulsion effectively penetrates below the surface of porous materials carrying waterproofing resins deep into the pores of the substrate.

The breathable waterproofing membrane allows moisture vapour inside the substrate to evaporate whilst protecting against water penetration and damage. The invisible membrane is protected from ultraviolet light and is long lasting even under heavy moisture conditions.

Assuming application instructions and coverage guidelines are adhered to it provides effective water repellency for years in just one coat.

The RSLTWSU5L waterseal can be used on brickwork, stone and other cement surfaces and has the following technical details:
Coverage: 4m2 / litre
Size: 5 Litre
Flammability: Flash point above 61(degrees)C
Application: Brush or roller
Drying time approx: 2 hours

Very happy with the product, the price and the speedy delivery. Would definitely use this company again and would be happy to recommend them to others.
Jan, Bracknell 04/10/2016

I found the water sealer very good, even with one coat. We get driving rain on the front of our house where we live in Wales, so a good wall sealer is a must. This product seems to do this job very well. Well done Thompson's for a great product.
Kelvin, Aberdare 28/09/2016

Swift delivery and product in excellent condition.
Christopher, Bristol 22/09/2016

This water based one coat is brilliant ! I tried to give a second coat to a very porous stone wall and it just ran off ! I had , in days of old, used the old solvent based one which took 3 coats to achieve the same results !!! Pleasantly surprised !!!!
david, Bingley 19/09/2016

Very quick delivery and price was very good, would thoroughly recommend, many thanks UK Tool Centre.
John, Backwell, North 16/09/2016

I have used this product before, and it does exactly what it said on the was excellent value for money.I would recommend this product to anybody who needed to waterproof outside areas.
Peter, Paignton 19/01/2016

Great price and prompt delivery. Definitely will use again!
Idnan, Bolton 19/01/2016

Have used this product years ago when it was clear and contained a solvent and worked well.As with all the products you can no longer buy, found the replacements far inferior to the the original,but probably as good as similar products available.Toolcentre prices work out by far the cheapest for this product especially if ordering several cans,with speedy delivery.just a shame you can no longer get the original product thompsons built their name on
charles, swansea 02/01/2016

It does what it says on the tin
peter, holme on spalding moor 30/10/2015

This is the stuff to use .. put it on with a pressurised sprayer, 5 litre Spear & Jackson is the one I used make sure you wear all the safety equipment goggles and mask are essential, apply when dry and no wind making sure you cover all the area in 1 metre squares,give the brickwork a good soaking. Recommended to use Thompsons Ultra by a specialist builder.
John, NEWHAVEN2c 12/06/2015

I have used this for years. It is easy to use, does not clog up my sprayer and does what is says on the tin and great value from UK Toolcentre.
john, Eastbourne 11/06/2015

First class item / exactly as listed / best value out there for 4 cans / fast delivery / highly recommend to all. Thank again - "I'll be back".
Miklos, HALIFAX 27/03/2015

Very easy to use. I used this in a sprayer and it was perfect. No waste or spill.
hanif, South Croydon 30/07/2014

This is a good product. I have used it before but the composition has changed to comply with solvent restrictions so I will have to wait to see if it is as effective.
John, Coleford 17/05/2014

I highly recommend this company. Items delivered as promised and at a great price. Definitely use again. Many thanks

Super service super product super price 5star all round
keith, Poole 05/02/2014

Had tried various water seal (silicon type) products and whilst cheaper than this premium brand they needed twice as many coats which then made them actually dearer and time wasting. One coat does the job in one as per tin!! In recent rains the cheaper brands do not bead they do not seem to barrier the rain even after two coats.Thompsons external walls showed no sign of being porous and the rain beaded on the brick surface. I preferred paying Tool Centre price for something I needed a lot of. Some products do 25 ltrs however the liquid needs a good shake up which one cannot do with 25 ltrs. Lastly like the fact it is water based material as opposed to the old silicon which used some pretty evil smelling and probably toxic carrier.
derek, DOVER 08/11/2013

Does what it says on the tin, better than the others, and you only need half as much, so it is cheaper as well.
Christopher, Winslow 04/09/2013

Excellent service and speedy response. Very happy with service and item ordered, I would definitely recommend them.
Altaf, London 23/08/2013

Quick service at a good price I will use again
lawrence, waterlooville 25/04/2013

used this product numerous times, brilliant ! especially good for sealing pourous brickwork / where lead trays on a chimney are not working / single skin conservatorys / porches / window reveals, where the vertical damp has been overlaped by plaster & moisture is tracking across.
m.herbert, Poole 25/04/2013

All as expected with the product. Price very competive complete with a first class delivery service!
John, South Shields 04/04/2013

Excellent communications and delivery of the product, which is exactly what I purchased. Price was the best I could find for the product from a quality reputable manufacture. Definitely recommend and use the product company again. Thanks
Derek, Waltham Abbey 18/02/2013

We bought this as it can be applied when the surface is not completely dry - a requirement in Scotland. It did what it said on the tin.
Pauline, Biggar 24/01/2013

The best waterproofer in existence! 1 coat, job done! brilliant stuff.
