Sand and cement is hard work to get there, batch, mix and carry.
Get your big gorilla tubs up on the scaffold, whisk up and use like you would sand and cement.
But not all ocr’s are alike. Johnstone’s is nice and creamy followed by Weber. But then others need a knack like Parex Parmurex.
When you have a job, give us a shout telling us what the substrate is (brick, block or mix) and who stocks Who’s ocr in your area and we will advise on how to go about it.
Get the right ocr and you will never want to mix sand and cement again.
