Base coat with mesh


New Member
Hi there
I have recently been using bagged renders instead of sand and cement.
Sometimes 2 passes fresh in fresh and sometimes scratch then topcoat.
Occasionally using alkali mesh in the base, but always wondered why some lads leave the mesh slightly exposed in the base coat before they top it of the next day.
Is this just giving the topcoat a key instead of completely covering and scratching.......?
