I priced a job today to render a bunglow!!

[s.p.t plastering]

But it's really pourus bricks I'll be rendering over, he wants it tyroleaned anyway.

But what would u guys put on the bricks frist before scratching?

I was going to use pva, or neat sbr.

Then a 4.1 scratch coat with waterproof, and then 5.1.1 top coat with lime.

Would it be ok to just devil float as I'm tyroleaning?

Some of the stuff is low level and small panals, do going to do it on my own, apart from the gable, as the price is tight to.

just scratch it with waterproofer in it

give the brick a good drink from a hose before scratching. no need to devil float just float it

just scratch it with waterproofer in it

Iv'e seen people do that before though over pourus bricks, and you could brush the scratch cpat off with your hand when dried out, where it's dried to quick.

There red bricks.

If you are worried about the scratch going powdery you could add a bit of sbr and fibres to the mix.

if i use sbr...... in the mix, do i need to put waterproofer in aswell or just plasticiser, or does sbr act as a plasticiser.

if sbr and fibers make the sand&cement stronger... and less lightly to crack.... why bother with waterproofer. cheers

Just plasticiser as the it dont lay on very well with just sbr.

the clue is in the name "waterproofer".

i thought sbr was a waterproofer aswell.....?

 

[spunky]

it is mate it pretty much does everything you ask .......people dont use it all the time cause it costs 3-4 times the amount of waterproofer/plasticiser
