Sigmarine 28 Alkyd Primer and Undercoat

Sigmarine 28 alkyd primer and undercoat in grey and redbrown, 5 L and 20 L. The heavier primer and undercoat in the Sigmarine system.

• Check before ordering: primer and undercoat in one, so it can be built up to the film thickness the scheme calls for. Follow the overcoating interval — alkyds harden with time and a late topcoat sits badly on a fully cured undercoat.
