Seal a block wall

[Tony Tydeman]

Hi Guys,

I have a concrete block built extension on the garage. I mistakenly thought that masonry paint would stop the water seeping through.

Does anyone know of a quick and easy way to seal the outside please?

Render

Thanks for the reply.
As far as I'm aware render doesn't bond/stick to masonry paint.

You would need to fix mesh to the block first.

Scabble the wall or run a cup grinding disc over it
