Needs Help again

Subject: Needs Help again Sun Jul 07, 2013 2:22 pm

Hi guys and girls need help again, I had my house rendered last year now it is covered with thin cracks, and it looks like a jigsaw. The builder as said it is shrinkage and want me to paint it with non-water base paint, which he said would fill in the cracks.
I am not happy with this and with your help could anyone point me to a firm, which I could get an independent survey from.

Thanks TG

Did you get a receipt for the work?

I seem to remember Iggy gave me some advice after I'd built and rendered a wall.

No, they came back yesterday acknowledge it was shrinkage in their rendering, it the remedy I not happy with, I had witness there with me. I would like a some advice with an surveyor and take it from there.

It could be shrinkage it could be movement in the wall, if the wall has been there a long time and has always been in a good state of repair then movement or subsidence is less likely. The render can crack for a variety of reasons, too strong or weak a mix will crack, or if the bays of render are too big (this is one of the reasons why metal beads are used.)
An Architect may be good to speak to if you know one, he would definitely know the name of a surveyor to use.
I would never use a non water based paint on the outside of a house, if water gets in behind it, which it will, then it can't get out and you will get huge water bubbles on your wall. Usually to repair a crack in render you cut it out with a disk cutter and put an oil based mastic (not silicone) in the crack and then paint it with a good quality water based exterior emulsion (Dulux.)

Thanks for that, they are fine cracks going every where like a big jigsaw puzzle, to many to cut out. I will try to take a photo.

The wall sound solid. there is no hollowness to it when tapped. I am thinking it could be the mix.

Simple fact is TGWU is that it sounds as though it wasn't done properly, and the builder should be taking it down and re doing it. Painting it isn't a long term solution.

How you get him to do it is another matter.

Definately the builder at fault I would say, especially after such a small time scale
