March 22, 20206 yr Hi again chaps- hope this'll be a quickie. How to best apply a base/ primer coat on new render? drying 3 months now.. so can start thinking on this job. I've decent dulux masonry paint (white wales cottage) ready for main coat but £dear so ideally not use this 50/50 or whatever a primer coat might be. Thanks- zoothorn rollo.
March 22, 20206 yr Not sure it needs a base coat, just two coats of standard paint Just checked and MIs are one coat done at 1 part water and 5 parts paint, then one full coat over.

Actually Peter Ive just dug out some no-nonsense 'Bare Plaster' undercoat white paint.. would this be suitable? [sorry what does "MIs" mean]. thanks zoot Edited March 22, 20206 yr by zoothorn

March 22, 20206 yr Do not use emulsion !!! It will come straight back off. MIs - Manufacturers Instructions - on Dulux exterior weathershield are to do as I said. One coat at 5:1 paint to water then top coat with full strength.

I was sure there was some sort of primer/ adhesivey thing needed even before the 1st 5:1 first coat. No?
