I'm looking for an experienced painter/company who regularly deals with calcimine and can also repaint. Is it worth removing it or should I get it treated somehow? I'm located near Bondi. Feel free to PM or post with suggestions (but not spam). Thanks. Re: Calcimine walls - need a painter 2Jan 29, 2012 12:03 am Kalsomine was an old cheap coating of powder mixed with water, applied with a broad brush leaving a 'powdery' finish. Hopefully yours has only a couple of coats. Its general practice that Kalsomine must be removed before ANY painting is done as new paint wont adhere to the powdery surface Its removal (from my experience) is a very labour intensive messy job, usually done by the owner as contractors will charge the earth. Google Kalsomine and read up on the product in other reno forums Arfur Re: Calcimine walls - need a painter 5Feb 21, 2012 9:43 am If it's a classic lime wash you are not risking anything except dust. It's basically made of lime and water, when lime is hydrated it become similar to chalk. If the kalsomine is in good state you can fix it with primer and then use a lime based paint, necessarily a paint that let the wall "breath".

All kalsomine walls and ceilings Ive seen leave some powder on ones hand when wiped over, so I think you would be brave indeed to attempt to paint over without removing it.

But there is a tradition of lime wash in Europe and it last very well, but of course it's good quality product at the beginning.

But there is a tradition of lime wash in Europe and it last very well, but of course it's good quality product at the beginning. I very much doubt if the OP was talking about the European type, rather something that was used around early last century, and by the looks of it, was applied with a broom. If you wet your fingers and lightly rub across the wall it comes off. I can remember tall packets of Kalsomine in my grandfathers shed Arfur Re: Calcimine walls - need a painter 9Feb 27, 2012 7:43 pm The Correct way to paint old flaking Calcamite paint is the follow: - Scrape most of the flaking paint (make sure u wear dust mask and safety eye wear). - Wipe walls down with a damp rag and clean area. - Use Dulux Sealer Binder (Oil Based, must be oil based if use an Acrylic undercoat the paint would NOT stick to the Calcamite and will peel off in 6 months). Let it dry for 24 hrs. - Fill any imperfection with the proper filler ( must fill the holes and cracks after sealing the surface with the Binder) - Spot prime the patches with any undercoat (Acrylic will do ). - Then 2 coats of any topcoats ( you can use any Acrylic of Enamel Paints on top of the Sealer Binder). If any problems drop us an email and i'm more than happy in helping you with any questions.

I came across it by googling 'calcimine walls'. I have sent a message to the original poster to see if they had any luck but is anyone able to PM any recommendations to me? Thanks in advance. Re: Calcimine walls - need a painter 12Sep 10, 2015 9:38 am Kalsomine finishes are not good even for application of modern paint products. When I had the problem a professional painter friend advised me to fill a bucket of water and take a piece of burlap (hessian) and wash down the entire surface until it appeared slightly pink. That meant I was back to the original fibrous plaster. When all dry then add Emulsabond to tinted sealer and one or two finish coats as per paint instructions. The last time I looked at the work it was perfect after 11 years. ..no flaking Enjoy the washing bit. Re: Calcimine walls - need a painter 13Sep 10, 2015 8:25 pm you can paint it. Sealer binder is formulated for this very type of thing. I would however recommend sealer binder followed by 1 step PSU oil based, then go ahead with your topcoat. Render your bathroom walls, two opinions versus the one, makes you wonder. 3 6045 The spacing of the studs looks pretty large especially for a load bearing wall. 3 11106 Nope, only on the inside, I've literally has my ears to the brick outside and can't hear anything. I can sort of 'reset' the noise by pressing firmly on the studs. This… 10 11736 |
