About This Product

Vegam Exterior Primer is specifically formulated for exterior masonry applications where moisture, UV and biological attack are ongoing threats to the paint system's integrity. Its anti-fungal biocide package prevents algae and mould from colonising the primer layer — protecting both the primer and topcoat from premature failure.

The deep-penetrating resin consolidates and binds the surface, reducing differential porosity that causes uneven topcoat absorption and patchy appearance on exterior facades.

For efflorescence, treat with dilute acid wash, neutralise and allow to dry before priming.
02

Apply Exterior Primer

Dilute up to 10% with clean water. Apply using brush, roller or spray. Work primer into all pores and crevices.

03

Allow Full Cure

Allow primer to cure for minimum 6 hours before applying topcoat. Overnight cure recommended in humid conditions.

04

Apply Vegam Exterior Emulsion

Proceed with Vegam Exterior Emulsion as per its application guide.
