We've got a thin coat job to do but wanted to ask some questions first.
its an insurance job on a new build where oil has been thrown over some brickwork. the insurance have sent round 2 lots of industrial cleaners to try and remove it but its still stained so they have told the policy holder to have it rendered.
do i need to use a primer? ive done thin coat systems before but only ever over new breeze blocks never over existing bricks. also will there be any problems with the oil coming through? as far as im aware there's no longer any residue its just staining.



thanks in advance
