exterior paint for pebbledash walls?
- Thread starter Peter G

Smooth, because the aggregate in textured paint holds dirt and the paint will therefore break down quicker.
Cheap paint is also a false economy. Dulux trade Weathershield masonry paint is worthwhile on exteriors - and always two coats.
If the pebbledash has not been painted it is a good idea to use a stabilisng sealer first. If it is previously painted then no stabiliser is necessary, unless the existing paint surface is powdery (wipe your hand over it and if you get a chalk like residue on your hand it needs stabilising). I agree with the poster above - if it hasn't been painted then you are creating a job which will need repeating prob. every 5-7 yrs, more often if you don't do it right or use cheap paint.
When you paint masonry the first time, you want it to soak in because this gives it a grip on the surface; however it cannot soak into the dense pebbles and that is why I would use a stabiliser on unpainted pebbledash.

Well smooth will go on better ( easier) but are you sure you want to do this? - Don't underestimate just how a big a job it is. It depends how big the wall is, of course. But this type of paint is heavy. Every brush load is heavy to work with.
You need to brush the surface down with a wire brush or similar before you start.
You may wish to use a "stabilising solution" first, to ensure the paint adheres properly. The stabilising solution may be watered down with a little turps, this will allow it to soak into the pebbledash a little better. If you apply stabilising solution "neat" it just forms a plasticky sort of coating on the pebble dash, which will flake off over time.
All I am saying is, once you paint a pebble dash wall, don't forget you will have to RE- paint it every few years. To maintain it. Otherwise it will start to flake. You have "made a stick for your own back" , in effect.
