Painting new render

[zoothorn]

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.

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

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-?

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]

Bare render, 5:1 paint to water according to Dulux.  Nothing else needed.
