brush or roller?

[kjhoskin]

I need to get the front of my house painted this summer its not been done for probably 10yrs. Its an 1820's built stone cottage so the walls are quite rough. I've got about 100 sqm to paint (its the front and one end of the house) My farther in law has a scaffold tower which I'm going to borrow to do the 1st floor and I'm going to pressure wash the green algae off first. So what do you recommend, a masonry brush or a roller? And as for paint Dulux Weathershield (whats the difference between Weathersheild and the trade version?), or Sandtex.

An old pic of the house c2009 its had new windows since and is now looking rather green!

Definately a roller but make sure you get an exterior roller, They are rougher and have more 'fluff'

you say it is rough. How rough? Maybe a roller will not reach into the depressions.

You can try it with a roller dipped in water to see.

A roller will work on smooth render but not on stonework. I would have gone straight to a brush.

I was talking about a roller like this.

I have painted a rough pebble dashed external wall with a roller having no problems so on a stone wall like yours (which is relatively smooth in terms of stone walls) it should be fine.

I think I'll give the roller ago, I've got some cash to spend at B&Q so I'll get some rollers and some decent brushes.

Any comments on the paint to use?

Dulux Weathershield Masonry Paint. It's not the cheapest paint but will last

 

[kjhoskin]

any ideas what the difference between weathersheild and trade weatersheild the trade version is quite a bit more expensive

 

[karun]

Yes the trade paint is of a higher quality and from experience lasts longer than the retail paint. In addition, the trade paints are concentrated and are to be watered down as desired (hence why they are more expensive). The retail paints are already at general emulsion consistency for the average 'diy'er and can be used straight from the bucket.

ok I'll have to do the maths and work out the best value/hassle. B&Q are doing 3 for 2 on both types at the moment. Trade is 2.5l tins and retails stuff is 10l

I am currently using Kingfisher Weatherflex and can honestly say it's the best and easiest exterior paint I've ever used. It comes with a 15 year guarantee and ordered online 40ltrs worked out cheaper than Sandtex & arrived within 48hrs.
