Water stains, soot, rust streaks and nicotine yellowing bleed through water-based paint even after several coats, because the water dissolves the stain and brings it back to the surface. IZOMAL is a solvent-borne POLIFARB paint that forms a barrier a dry stain can no longer pass through.

How it works

One coat of IZOMAL goes under the topcoat. It dries in 2 hours, after which the surface can be painted with any POLIFARB water-based paint. No primer is needed. It also adheres well to surfaces painted with oil or alkyd enamels, so old oil paint does not have to be stripped back to concrete. The barrier against yellowing is declared for over 8 years.

Preparation and conditions

Stains must be dry: if a leak is still active, fix it first. Mould and fungus are treated with a dedicated product beforehand, and old lime and glue-based coatings are removed. Apply by brush, roller or spray at +5…+30 °C and up to 60 % humidity, thinning with white spirit. Consumption is 150–180 g/m² per coat on non-absorbent surfaces and 170–200 g/m² on absorbent ones. The paint is flammable, so keep the room ventilated. Pack size is 1.1 kg; do not freeze.

Questions and answers

How many tins for a 10 m² stain?

One coat over 10 m² takes 1.5–2 kg, which is two 1.1 kg tins.

Can IZOMAL be left as the final coat?

Yes, with at least two coats 2 hours apart. The finish is semi-matt; on its own it is used on brick, concrete and cement or cement-lime plaster, indoors and out.

What to paint the ceiling with afterwards?

Any POLIFARB water-based paint, for example SNEZINKA; see “Ceiling paint”. More on stains in “How to cover ceiling stains”.
