HELP, HOW DO I STRIP AND PAINT THESE WINDOW CILLS

[francspencer]

Hi,

What is the easiest way to strip these concrete cills (i think maybe sandstone)?
I have a heat gun..
Then paint with homebase primer and undercoat all in one.
Then weathershield white gloss.

When stripping and painting my back windows I never achieved a completey smoth glass like finish due to the roughness of the concrete.,
Do proffessionals use a really thick undercoat or some special paint?

You usually use masonry paint. Glass like finishes are for the inside.

Joes right, 'rough n ready' for exterior..its all extra character! Masonary paint pref' for sills..Weathershield or similar ..Stay clear of Homebase watered-down(or spirited) rubbish

The hombase paint is a primer and undercoat all in one for masonary.
I used it on my back windows and was a great base for the dulux weathershield.
I'm now thinking i should swap the dulux weathershield for wood and metal for weathershield masonary..

I used the weathershild gloss on the back windows, (the paint stilll looks great and no signs of blisterig or cracking) over a year ago.
What are the downsides to keeping with this paint for the top coat?

thanks for all your help, i'm hear to learn, sorry for all the questions,

Are you referring to the black Weathershield gloss on the actual window frames? If so then definitely stick with the gloss ..If you mean the sills then you can paint them gloss if you wish but theyll need some attention to detail in preparation ..If theyre not smooth & sound then they'll look a bit dodgy !

No, not the frames, just the sills.
I plan to completely strip so hopefully will be good preperation.

Ah,ok.
Well if you want a nice SMOOTH glossy sill surface your going to need strip off all loose flaky layers at least or completely back to the stone/concrete surface..I find it then easiest to apply a thin layer of P38 filler (the car body filler , dont buy from Halfords etc it'll be too expensive!) to the whole sill if stripped or just to the 'holes' if not.
(this stuff never cracks etc. Use it as a woodfiler too! tip of the year)
If the stripped/half-stripped surface is not to rough then a few thick coats of Weathershield or Stronghold undercoat should level it off sufficiently to acheive an acceptable glossed surface

Pefect thanks!

car body filler was fantastic, really pleased with results.
I love this forum.
