Use of PVA

by Graeme Clark

It seems that PVA has a use on both high and low suction surfaces, is this correct.
On low suction surfaces it’s acting as a bonding agent (glue?) and on high suction surfaces as a sealant to reduce porosity?
Have I missed the point?

Answer
You are correct Graeme - it will indeed help on both - in the ways you describe.
