Could you tell me the best paint for external use on smooth render (that has been applied on block work)

Many thanks

Dulux Weathershield Exterior trade emulsion.
Glidden trade exterior emulsion
And at a push, Sandtex exterior emulsion

Thin the first coat, then give it one or two full coats.
Don't apply any sealer / stabiliser to the surface first.
Don't think about doing it when the temp is below 9-10c, or when it's likely to rain.

(I'm a decorator too )

Sorry, I completely forgot it was your line of work as well!

So no undercoat with anything else needed, just thin the actual exterior paint for the first coat?

Many thanks

That's ok, sometimes I completely forget what I do

If it's all new render then nothing else should be needed.
If any is flaking or chalky, then you'd need to stabilise it.

You can get 'all weather' masonry emulsion that is solvent based.
If you plan on using this stuff then the preparation is a different ball game.
(I try and avoid using solvent masonry paint wherever I can, in fact, I try and avoid exterior work full stop!)

Thanks Zip.

I'll need quite a lot of the stuff. Any idea where I might get the Dulux at the best price?

You could try a Dulux Decorator Centre - they often have offers on external paint this time of year (obviously because no ones using it yet).

Also, they're usually open to haggling with the shelf edge price.

If not them, try Brewers.

Don't forget though, any colours other than white, magnolia and possibly a few other 'neutrals' will have to be mixed.
At least with ready mixed colours you can take back what you don't use and also no chance of slight variations in machine mixed colours.

Thanks Zip.

Final (stupid) question please?

The Dulux weathershield range comes as 'smooth' or 'textured'.

Does this mean they are for use on either smooth or textured masonry or that the 'textured' paint can actually impart some kind of texture to smooth masonry?

I hope that makes sense

The textured has a fine aggregate added to it so is rough to the touch.

If you paint already smooth walls it'll make them a bit rougher.
I can't remember the last time I used the textured stuff tbh.

It's pretty good if your walls have very fine cracking or crazing in the render (hopefully your new walls won't have this...!)

As above what Andy has said.

But I can say we used some Sandtex white - textured paint last year on a art deco style house, must say it was lovely to put on, bright white and dried quick, nice fine texture to it..... The price was very good too, buy through Crown Decorating Centers.
So don't dismiss it.

Many thanks.

It's up now, even though it was raining a bit

I went for dulux weathershield smooth masonry in county cream.

good choice.. re did my outside a few years ago.. with the same





I managed to get a few tin of FREE paint after there was a fault with the original tins, it faded quite quick and reacted with the lime in the render. So a few hours a night over a week and I got it done, one coat needed as a top up.

You missed a bit.
