Default Sealant for external walls

Hi

I'm told there is some sort of sealant I can paint on external walls
that will help repel water, and hopefully prevent damp getting into
the walls.

I can't find anything on the internet - can anyone help?

Thanks in advance

Simon

Simon,
You should be able to buy something like Thompsons Damp Seal liquid from
most DIY sheds.

Easy to apply with a creosote/fence brush - donot try using a standard paint
brush.

Cheers
Steve



But not until the wall is dry! If not, the only way for the moisture
already in the bricks to go, is in.

On a lot of walls this is a bad idea, and in fact makes things worse.

If you have a problem with damp, the solution is normally to fix the
cause of the damp.

Thomsons Waterseal if you want a clear coating. Onle effective on bare brick
or masonry where it can penetrate freely, and, boy does it penetrate. Best
done in the summer when the wall is bone dry. Think in terms of 10 or 20
litres rather than retail sizes. www.sovchem.co.uk
Use a solvent based masonry paint like Johnstones Stormguard if the walls
are already painted.

but I can't stretch to having the full render treatment - so was

after
something I could do myself to protect the walls.

Thanks



OK this makes things a bit clearer. Some qs:

why do you want to render the walls? Or do you maen something else by
'render treatment'?
what are the walls made of, how old, and in what condition?
what problem are you trying to solve?
