Brick weatherproofing

You obviously have never used this type of product .
I have used it on two buildings and it works ; the treated buildings , which had damp ingress , have been totally dry for more than five years.
My advice is not flawed and is based upon actual experience - not dreamed up at a keyboard.
Do you have any examples to illustrate your fanciful notions.

Calm down tony6403 and there really is no need for your sarcastic manner.

The product does what it says on the tin. For decades it has been a staple product of maintenance men, after sales customer care operatives and cowboy builders. Of course it works, for a while, but the reality is it is a sticking plaster approach which is not a permanent cure. It can have adverse effects if not used with thought.

The first rule is to prevent the water problem occuring - not to adopt an automatic response to apply Waterseal. In OP case there is a brick wall which is meant to be wet, so Waterseal is one solution, but not the best. It is OP decision to go ahead - we are only here to point out the pros and cons.

Furts , totally calm here :cool:
No ridicule intended, I should have toned it down. (I have to say that I still think that you have no empirical knowledge of these products).
This discussion has prompted me to accurately work out when I did apply the waterseal to the buildings to which I referred above.
Time flies - it is eleven years ago that I used it on my workshop and it is still bone dry inside. No adverse effects whatsoever.
Six years since I brushed it onto my garden store , again dry and no down side.
You say that Waterseal is one solution but not the best. I'm curious as to what would have been better.

I have far more years experience of Waterseal, and similar products, than you might imagine.You have used the product twice in eleven years - this means mse users cannot regard your opinion as definitive.

For example your coating would not have lasted had it been applied to a chimney on the Northumberland coastline. Equally if diesel100 has a garage at an altitude of 1500 feet facing the south west winds in Wales it would be unwise to apply Waterseal.

To reiterate - the product works, but it has a variable lifespan, it must be used with a technical judgement, and it will forever be associated with bodging builders, and contractors who tow a caravan and give a guarantee that comprises of a scrap of paper and a mobile phone number.

In an ideal world diesel100 would be considering dry lining his garage wall, and allowing for a membrane, or coating the wall with a porous paint, hence the discolouring etc. will not be as obvious.

As a general rule, the bricks should left to perform as nature intended them to and not be coated with any chemicals. If chemicals are applied this should only be after all other common sense, technical routes, have been pursued, or failed.

Furts -
After being effective for the last eleven years (and my workshop still showing no signs of water penetration), it could be said that this stuff has easily passed the test of time.
Your peculiar ideas are based on bricks not being able to "breathe" once the product is applied .
I give below an extract from Thompson's product data sheet ; it seems that they have addressed this issue.

Thompson’s Water Seal utilises hydrophobic technology to deliver invisible protection against water damage. The deep penetrating formulation penetrates exterior dry porous surfaces to form a breathable membrane that allows moisture vapour inside the substrate to evaporate whilst
protecting against water penetration and damage.
