Products for more severely damaged surfaces are more closely related to plaster than paint, but for those nor wanting to employ a professional plasterer, there are supposedly "easy to use" options available that are generally non-toxic, with a low-VOC content. Not all are popular on the DIY chat boards, though, and they're not cheap, either Skimming involves putting a thin coat of plaster on top of the existing plaster and is the best way to achieve a smooth finish on walls that are generally a bit battered or have large areas of damage or uneven surface, which would be difficult to finish well using a filler.
Prior to skimming, a coat of a PVA polyvinyl acetate "bonding" is applied to stabilise the surface to provide something for the plaster to stick to. This is a job for a professional plasterer who will use all their experience to do the job far more quickly and more perfectly than you could ever hope to unless you fancy enrolling in a plastering course yourself.
Despite the chat room complaints, a plasterer's fee normally represents good value for money, even when skimming. For walls with big holes, large cracks and lots of loose plaster, it is often necessary to get the wall, ceiling or whole room replastered. You could save money by taking off the old plaster yourself but, frankly, this is messy, hard work and you could end up taking off more than you should - thus making the job more complicated and expensive.
Get a professional plasterer who knows about these things to take off the old as well as apply the new. Replastering requires two coats: a basic, coarser plaster followed by a smooth, thinner skim coat. For plasterboard walls with extensive damage it is better ask a builder and a plasterer to replace the plasterboard, which may be expensive but worth it.
These days most people want to get rid of any textured coatings, but believe it or not they are still being sold - not only as a decorative feature mainly for ceilings but as a cover-up solution for tatty surfaces. Frankly, these are best avoided as they generally look horrible - if surfaces are really bad, it is best to get them skimmed. Before painting any surface, it should be free from dirt, grease, rust, dust and loose flakes of old paint.
Paint over knots with "knotting", otherwise the sap in them will bleed through subsequent coats of paint. Is there any fine grained, tough, smooth white filler or plaster that comes in a powder that you can buy in the high street. I've got some fine and not so fine cracks in the wall that I want to fill-in and then paint over.
I bought some of the Polyfilla stuff but they're all dark grey? The paint is white so I'm trying to avoid having apply to many coats. AndyDavis , 25 Jul Polyfilla for cracks.. Diyisfun , 25 Jul Thermo , 25 Jul You have bought the wrong type of polyfilla thats why As Thermo says gyproc board filler easy-fil is very good Look for interior polyfilla Be careful with the ready mixed stuff Zampa , 26 Jul I always mix filler with the paint I'm going to use instead of water Zampa , 28 Jul I've never encountered any problems as yet but I've only ever filled little holes with it, suppose it would be a pain on bigger jobs.
