hey i was wonder if anyone and im sure someone out there is about to help me here,

my roof is peeling inside and i havent tried to take it off but by looking at it i know there is going to be big chunks that are going to be easily removed but when ive finished removing them im worried there is going to be uneven paint levels on the roof due to the scrapping off the lose stuff, i am wondering how do u fix this promblem?

thanks

I imagine you would need to get up to your ceiling and scrape off all the loose paint that you can. Then the best way is probably to use a skim coat of plaster to fill the sections without paint and sand smooth so you no longer have the paint edges showing. Then you would be best to apply an undercoat because of the difference between the painted and plastered sections ... then paint with you top coat.

Sounds fun ... enjoy!

OBBob has the right answer of using a skim coat of plaster to level out the ceiling. Before you do this, scrape off the peeling paint and using a brush apply Bondcrete to the areas that you could not get the paint off. Be sure to brush around the edges so that Bondcrete can penetrate and glue the existing paint to the ceiling. finish off with skim coat and then paint. You should refrain from using a stucco type paint to the ceiling as it is ugly and holds dirt.

Be carefull using Bondcrete! Check with the manufacture of the boncrete.

Boncrete is not suitable for all plaster products and painted surfaces. I never use it as a rule, as the last time we used it, the patch of plaster we did peeled off in one giant slab. The bondcrete did not take to the painted surface.

We rang the manufacturer of the bondcrete and we were told it will not adhere to some paints.

Now we just take the time to scuff and scratch up the are to be done to give the plaster something to key to.

OBBOB is correct, I have just last week had the same problem, the whole ceiling had to be scraped, the only bits that wouldn't come off was where the sheets where joined.

I used a light rapid set filler, sanded then 2 coats of undercoat sealer then 2 coats of quality ceiling paint, turned out great. Took me a week to do as I made sure each coat was dry before applying the next. It worked out 1 in the morning and 1 in the afternoon, then in the meantime did the walls and cleaned as I went.

Most paint companies manufacture a special sealer/binder for use over old paint. Perhaps you should stock some at bunnies.: -

Description: A premium quality preparatory product which penetrates, binds and seals chalking and underbound paints to ensure a solid foundation and good adhesion for succeeding coats of paint

Uses: Old chalking and powdery paint work including plastic and enamel paints, kalsomine and corroded fibro sheeting
