Zinsser Bulls Eye 1-2-3 - Primer-sealer - Stain Killer - 2.5 Litre - Grey

This was used on uPVC windows. 2 Coats used but 1 was probably sufficient. Created an outstanding bond - very quick to dry, consistency on the brush appears quite thin - but coverage on application is great. Brush strokes can be controlled and strokes are of low visibility, assume spray or foam roller reduce this further. Used with Zinsser allcoat exterior top coat. Finish appears strong and finish far exceeded expectations- which sounded risky coating uPVC. Rewarded with good surface prep - but will likely work well without.

Used it for for undercoat changing brown to white, a couple of coats then two top coats of Crown stay white quick dry satin and looks great.

Very pleased with product covered dark orange stained doors really well.

Used over old oil based gloss after wash down with Krud Cutter Gloss -Off and before applying water based satin, seems to have worked really well with good adhesion.

Not the cheapest primer, but very good quality! :)

This allowed me to paint my uPVC door without any issues... Definitely recommend!!
