fixing to a very uneven surface


Postby system_shock » Mon Feb 25, 2008 8:40 pm

Hello,

n my cellar I would like to fit various shelves and cupbaords to the wall. However the surface of the wall can vary up to 10cm. I have therefore thought about covering the wall - probably with a peice of MDF or plasterboard.

I have looked for some wall fittings that could bridge the gap where necessary. But the only product I have found is a fixing product from Fischer that allows a bolt to be screwed in and then a nut applied at a small distance away (max 3cm).

I thought the best way to do this would be to fix some peices of wood in the areas which need bringing into line and then attaching my peice of MDF over the top so it covers the whole wall and makes it flat.

As it's in the cellar it's definately a case of function over form, but I was wondering if there is a product that is made for this type of situation.

Thanks

Hi, Sorry its a bit late but i've only just joined having seen your question.I'm a plasterer and from experience i would say that the quickest way to level a wall would be to fix plasterboard to it using the dot and dab method (best done by a professional but very effective). Briefly it involves sticking the plasterboard to the wall using DRYWALL ADHESIVE or BONDING COMPOUND, because of the thickness of the adhesive applied (should be 50mm) and the quality of the product the plasterboard can easily make up the 10mm tolerance of your wall. This is a modern method used in houses with solid internal walls and this is fast becoming the most popular method to plaster internal walls in new build properties however it can be used on any solid internal wall. Oh, nearly forgot... after the wall has been dot and dabbed you have 2 options, skimming the wall (applying a 3-5mm coat of finishing plaster to the wall) or tape and jointing (covering all joins in the plasterboard with tape and feathering out the join using joint fillers (personally i'd have it skimmed). From there you can use plasterboard fixing to secure pretty much anything to the wall, bearing in mind you also have solid areas behind the wall where the adhesive has set (rock hard stuff).
Once again sorry its late but i hope this is of some help. For more advice speak to a local plasterer.
