Correct way to paint smooth cement render? Internal/Extern..
Hi guys, I've recently built a large garage outside that has been finished with smooth cement render both inside and out. I just wanted to know the correct way to paint this after it is finished drying out.
I plan to use sandtex masonry paint for the inside and Dulux Weathershield for the outside.
Any advice would be great.
Thanks ;)

Wait till spring at the earliest. It needs to be fully dry and a warm day with no chance of rain.
Masonry paint brushes are only a few quid and normally around 4 inches wide.
Brush any loose bits off and paint as normal

Thanks for the response pal, I need to paint the inside prior to Christmas if poss. Happy for the outside to wait until the weather improves. Is there not some technique to painting render? Diluted paint, pva etc to soak prior to good coats?

Re: Correct way to paint smooth cement render? Internal/Exte
Why do you need two different paints when both are suitable for exterior use? You have not been taken by the marketing of Dulux, the word "Weathershield"?
You can do the inside once it is fully dry and temperatures are give or take >8 degrees or so (the paint will say minimum temperature for application). If you intend making your garage into a workshop or spending time in it, perhaps consider an interior paint for the inside as exterior paints contain things (anti fungal, anti mould and anti whatever things).
For the correct way see the instructions for the paint you decide to use for priming new surfaces. You may have to use a thinner coat of the same paint or a specialist primer by the same company.

No, masonary paint is good to go from the tin.devs wrote:Thanks for the response pal, I need to paint the inside prior to Christmas if poss. Happy for the outside to wait until the weather improves. Is there not some technique to painting render? Diluted paint, pva etc to soak prior to good coats?

Thanks a lot for all the help and info guys. The Weathershield that ill be using is an off white colour to match the house.
I've bought some cheap tubs of paint that I'll water down prior to using the more expensive paints.
Many thanks, Devs.

Re: Correct way to paint smooth cement render? Internal/Exte
Using some cheaper paint before you use your better paint is like buying a brand new car and straight away putting remoulds on it (if you can still get them) to preserve the good tyres. Or to rephrase, you want as much adherence to the surface underneath as possible, why put a layer of cheaper paint in between?
