concrete question.

hi there

I'm doing a really quick repair job in an old house that I use for storage. I plastered up the walls etc and happy with that.

I then got this smart idea of drilling and screwing plastic poster boards to the top of windowsill (ie the ones on the telephone polls at elections I painted them white) as there are old wooden boards (sleepers)inside the wall to attach the posters at the top of the window sill. The plaster covering the wooden boards fell off over time. The wood is still good and not rotten. Its cut sleepers so plenty of strength in it.

I thought by screwing the posters into the sleepers would stop cold drafts creeping through and had the mad idea I could plaster over them for perfect seal. I was going to plaster over the boards then to seal them but from quick experiment the concrete after drying does not adhere too greatly to the boards. I am wiser now after finding out.

I have a stupid question but is there anything that would help stick the concrete to the poster boards? This is a quick repair job and I'm not living in this house just use it for storage and trying to insulate the walls at the windowsills. I should have plastered without attaching the poster boards but now I'm stuck with this problem.

Any solutions? I am a cowboy here I know but it's my own old house i am trying to repair without spending too much money. Not partucular on how it turns out once I can safely secure it.

Hopefully someone can reply and offer some solution.

Thanks.

I wonder if you tacked expanding metal mesh over them would that give you enough purchase for the mortar to take ?

You could fix plasterboard over the posters unless it's really tight for opening.

I never thought of that. That could be well worth a try.

the window is a sliding window it goes up and down at present so it opens and closes perfectly. That seems like a good idea what you suggested. Is there anything that I should be aware of by doing it that way?

if I drilled in screws good and tight through the mesh through the poster and into the wood. Then plaster over it and leave it dry well. Would that work? Again I'm not too concerned about the finish just want to make sure it doesn't all fall down and that I can secure it ok.


Thanks.
