Found 5th Sep 2014
Cracking deal on 5 litres of the "belt & braces" brand favourite for avoiding penetration (& mould) ..ooer, in terms of damp ingression.

Addsa decent amount of resistance to brickwork for many years , easily applied with an old (clean) pastebrush (wallpaper variety).

Get your job done cheaply before asthma, damp & expensive dehumidifiers make you cough out more money! (& whilst the weather is vaguely good).

can you link the screwfix one please? ..does it make your brickwork discolour, as a cheaper version I tried did (not good for red brick) whereas the thompsons ultraseal dried clear.

does this work on red sandstone?

Just to clarify, you CAN recoat old thompsons with new variant once the applied surface has stopped beading (ie ready for a new coat)
IF your old can was water clean up, & had low V.O.C. on the can it is the newer version.

If you have the OLD style, the new style will just run off if it is not ready to take (ie still active).

I personally have not had a problem with the new type!

N.P. ..i'm just a bod on the internet, not always good to get the laymans idea of what is correct protocol

No Nonsense Water Repellent Seal Clear 5LtrProduct Code: 57474 screwfix.Far better than Thompsons water based.Iv'e been using thompsons original silicon seal for many years in the building trade,The screwfix stuff is just the same £18 I bought a water based one thinking it was silicon type.I won't make that mistake again.

Den, perhaps you need to validate that, ..namely that SOME of "Thompson's" is now water based (in so far as flour is a component of bread) BUT it does actually have Silicone, (& some is other stuff maybe akin to value bread vs artisan, sic)

**** powers much of the internet in terms of hearsay, gossip & rumour, the original chemical constituents have changed in one form or another HOWEVER based on the same argument being put forward time after time on the internet it does not take a genius to check it out.

OK so it might not be as good as it once was "might" but your statement was inherently flawed.

"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".

taken from here http://www.thompsonsweatherproofing.co.uk/products/product.jsp?id=2

check the difference...

Q. What is the difference between Thompson's Water Seal and One Coat Water Seal Ultra?

A. Thompson's Water Seal is a solvent bourne, stearate based water proofer which can be used on a wide surface of materials such as brick, pointing, concrete, stonework, wood and other porous surfaces.
Thompson's One Coat Water Seal Ultra is a water bourne, silicone micro-emulsion based water proofer suitable only for use on brickwork, pointing, concrete, stonework and other cementatious surfaces..

(so basically it might apply to one product in the range, but not the other, ..yet still there may also be better / worse products out there on a like for like price, in this instance I am referring to ULTRA).

Thanks, please pass that info around to enlighten others who may be prone to misconceptions re the silicone aspect touted around.

Cheers.

Gus i don't need to validate that some of "Thompson's" is now water based.I'm only talking about the one you posted,As a builder using many gallons of Thompsons silicon sealer in 45 years of building thats my opinion.You feel free to use anything you like m8.

Look at the ingredient used in the description Den169 The ONE I posted, it clearly states SILICONE, my point being you are talking out of your backside unless you get it in context.

& subsequently you are talking out of context. "m8"

You are referring to a partial change in the whole ingredient make up compared to how the product you used, used to be, possibly prior to "SILICONE laced, Ultra-seal Thompsons" arrival on the scene.

When ripping the brands product(s) to pieces over several threads you failed to even provide a link to your new "personal" favourite for general use, which may have been handy as a comparison, perhaps you were referring to the "no nonsense" screwfix version!?

Fine I'll put the option you may possibly be alluding to .. screwfix.com/p/n…474 (this is made / distibuted by a company called Siroflex uk, & to best determine cost & performance perhaps speak to the professionals & ask salient question determining the plus / minus points of the two.

(coverage ranges between 2 to 4 square metres per litre according to info via a screwfix agent)

Compared to Thompsons *ULTRASEAL version of "Up to 4m²/litre depending on the porosity of the surface" site info).

I've also known some really **** builders / professionals regardless of how many years in the game.

What part of Silicone based don't you get!? to quote you Den "Thompsons is now water based crap"
"Screwfix sell a silicon based one just like the old thompson stuff far far better".

Well the difference is another product, in a distinctly different can, with distinctly different performance as a result of different chemical & molecular composition, whether it is stearates as a binder, softener, lubrication agent, or against oxidisation (allowing for longer storage for instance).

I have not got the 3 side by side to compare, I do have concern for V.O.C's released & am aware that this is a belt & braces solution not a permanent fix, if you need to re-apply this stuff you are better tackling the job by other means in order to resolve it not simply sticking plaster it, ..however, like many products it may be applicable to some.

But by the terms of the HUKD community this is a good price on this product compared to elsewhere right now so may serve purpose to those who prefer the brand, or are visiting b&q anyway, or based on previous application & the knowledge that when they used it it dried clear (unlike other brands purporting to do the same) such as B&Q's own (red can as was) cheapo option which actually often messed up brickwork with a long lasting surface haze ..for instance.

IF I had 3 or more different cans of this stuff then I could make a rational decision based on reading up, in field use on limited data based on test subject, porosity & each products CURRENT chemical composition, ..& no more.
