Painting exterior render

[paul_j_tomlinson]

The front of my 1950's house is rendered and painted with what I would imagine to be masonry paint of some sort. As this is visibly flaking off I decided to start scraping this off.

However, although it's relatively easy to get off the worst flakes there seems to be some sort of thin coating over most of the surface with a rubbery or silicone-ey sort of texture.

The previous owner of the house was a bodger and may well have used something completely inappropriate for the job. Or perhaps its some sort of stabilising solution ??

Questions are :

What's the best way of preparing painted render for re-painting ?

What's the best type of filler to use to fill any small cracks ? Tetrion ?

Does the thin rubbery coating sound like stabilising solution ?

Any recommendations for stabilising and paint products ?

Is rolling or brushing the new paint on better ?

Any tips ?

Thanks !!

Maybe. For larger bits I used two part 'epoxy mortar'

does to me.

I used sandtex paint. No staibilser. Is flaking where frost damages it. Soem sort of weathershieled coat probably good.

Certainly they are better than leaving it in the tin. ;-)

Brush is slow but less messy. Rollers fast especially on a long pole. Cut in round windows pipes etc. with brush. Then tape newspaper over all paintwork and windows and roller away. Its very fast - a long weekend is enough.

Get a pliolite based paint from Johnstones or a similar trade outlet. Requires no stabiliser and not much preparation. Expensive though

Undoubtedly.

I used that about 10 years ago as a temporary (ahem) bodge, and it's still 100% fine.

Disagree there. IMHO stabilising solutions are usually water based and soak in to the render - I think it sounds more like the previous exterior-grade emulsion

I used pressure washer -> stabiliser -> Sandtex paint (which definitely is slightly rubbery in texture if you pick it off somewhere it should be). Advice from this newsgroup (search for Max Bone! [I think]) indicated not to bother with the textured paint, just use smooth - the textured stuff just has sand added so you get less paint coverage.

I'd go along with that IF you can get a roller to work. Depends on how deep/rough your render is - mine was old pebbledash, and a total nightmare to paint, using a paintbrush with a stabbing stubbling action. Really killed my wrists.

Or a bloody long summer in my case!
