Pebble dash (or similar) removal

Its textured paint IMHO.

Would make sense - will paint stripper take it off like ordinary paint?

Sounds like it could be Tyrolean (cant upload photos at the mo for some reason) Google Tyrolean Pictures and something should come up.

It looks like a spray applied textured wallcoating rather than a render or pebbledash finish.

Some of the companies involved with this have a rather dubious reputation for dodgey cold calling sales techniques and making inflated claims for durability. However there may be some legitimate companies and if they offered a 25 year guarantee you may be able to call them back (if you can trace them).

Failing that I have heard it can cause a major headache when it starts to peel as it can be extremely difficult to over coat.

Try some searches for "textured wallcoating"

The previous owner of the house died before the house was sold, so I doubt I could find out who did it or when it was done - could well have been 25 years ago now. But yes, it does look more like a spray coating.

Hi Ed, good to see you.
It is actually the original render which is applied onto metal lathe.
The top coat was pebble dashed and what looks like a textured coating is simply years & years of paint build up applied by the Council and subsequent owners.

The image with the drainpipe on showing brickwork is from the rear or front of the property where the outbuilding/toilet wall meets the house if I am not mistaken.
Because this wall is single brick with no damp proof membrane, it absorbs moisture which in turn causes the render to break away. Frost during cold weather accelerates this.

A common mistake many people make is to simply re apply a patch of cement render to repair any damaged or decayed render. The problem being that cement render isn't flexible and over a short time it will also crack.
A polymer render should be applied or in some cases a flexible additive solution can be mixed into normal cement render which will allow it to move with the steel frame of the house.
Remember that all steel framed building expand and contract and this should be taken into consideration when repairs are made.

Hope you are well :j

Hi Marc,

I'm pretty sure it isn't original and isn't just the render as the textured coating it is on the steel cladding upstairs as well as the render downstairs. It isn't on the rendered wall in the passageway that goes through from the front to back in the single storey annex. Also, you can see that it has been sprayed on relatively recently as it's splashed on the end 30cm or so of the telephone wire where it is attached upstairs under the eaves!

The photos showing bricks aren't of my house. My single storey annex is built of concrete blocks. All the render appears to be in good condition, it is just the textured paint is flaking off.

I'll take a photo tomorrow, it's easiest to see from the upstairs windows where it's flaking off the steel and you can the the yellow paint underneath. Incidentally the exposed yellow paint is exactly the same shade as my neighbours, so I guess the two houses were painted at the same time.

Here's a closeup of the textured coating flaking off the upstairs steel cladding that I took leaning out of the bedroom window. You can see yellow paint on the steel underneath.

very typical, done many of these in th epast, best practise is to strip back and start again. I'm free. We did one recently with render board over the whole front and then K-Rend over SBX flat finish a bit more contemporary, and self coloured sono paint.

Thanks, but I'd rather just strip off the textured paint and repaint in a fresh colour. The local housing association have done what you suggested to the other half of the semi (and all their other BISFs) and it isn't an improvement from a visual point of view IMO. I don't believe I'd save on the heating to make it worthwhile financially either.

Just thought I'd post an update as I've finally got round to starting on it and thought others might find it useful as quite a few houses round here seem to be coated in this stuff.

I got a test pack of two types of paint stripper from http://www.stripperspaintremovers.com - they were very helpful.

Their 4-F takes the paint that the grit coating is embedded in off quite easily and then it can be washed off with a pressure washer.

Surface seems good as new underneath!
