zoothorn Posted March 22, 2020 Share Posted March 22, 2020 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.

PeterW Posted March 22, 2020 Share Posted March 22, 2020 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. Link to comment Share on other sites More sharing options...

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, 2020 by zoothorn Link to comment Share on other sites More sharing options...

Well no spiel specifically worded 'new render'.. but does say ok on conrcrete & brick.. & I mean render is a plaster, & isn't it just white emulsion thinned down a bit which is simply what masonry paint is-?

PeterW Posted March 22, 2020 Share Posted March 22, 2020 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.

Aha ok.. didn't know masonry paint was't a form of emulsion/ another thing learnt then. I was sure there was some sort of primer/ adhesivey thing needed even before the 1st 5:1 first coat. No?

PeterW Posted March 22, 2020 Share Posted March 22, 2020 Bare render, 5:1 paint to water according to Dulux. Nothing else needed. Link to comment Share on other sites More sharing options...
