TOOLS YOU WILL NEED:
Medium pile roller sleeve and roller cage/frame.
Roller scuttle (Something to put the paint in that you can roll the roller on the side of) If you don't have a roller scuttle, you can use a bucket and put a thin piece of wood about 12" x 24" in it to roll the roller on. This will make sure the roller has an even coat of paint all around the sleeve before applying to the plaster.
3" Paint Brush for cutting in with.
Suitable Emulsion paint. It is important to use a non vinyl paint as a Mist Coat. White contract emulsion is generally cheaper and perfect for the job.
Access to water. Clean fresh tap water only please.
HOW TO: Painting new plaster is quite a straight forward task, however it's amazing how many people make the same mistake which can result in not only the paint peeling prematurely but also lots of extra work putting things right the next time the plaster is painted. The first thing you will need to do is cover any furniture and carpets etc. with dust sheets. A Mist Coat is thinner than normal paint and so will therefore be messier than normal. Next create your Mist Coat. Basically this means thinning the emulsion paint you will be using in order for it to sink into the new plaster. If you do not do this then the paint will be too thick. It will sit on top of the new plaster and dry there meaning it will eventually just peel off. We would suggest then that you thin the emulsion with water to a 70/30 ratio. This should provide a suitable Mist Coat for you to use. Once you have your paint ready, you may wish to decant a small amount into a paint kettle for cutting in with. First begin by cutting in (this means painting close to the edges of woodwork and other areas without getting paint on them) a small area, be aware that as you begin to paint the Mist Coat will sink into the plaster quite rapidly and dry quickly. Once an area is cut in you can begin to paint with the roller. Roll your roller down the side of the scuttle (or board in a bucket) several times allowing it to touch the surface of the paint. This will make for an evenly coated roller sleeve. Now apply to the new plaster in even strokes making sure that you cover all of the fresh plaster within your cutting in. Repeat this process until you have an even coat without leaving any thick roller marks. This is achieved by rolling back over previously painted areas before they dry. Do not be alarmed if the area looks patchy when it is finished, this is normal and can be a good sign that your paint was thin enough. Once the Mist Coat has been applied, leave to dry before repainting in two coats of your normal emulsion. This can be vinyl matt, vinyl silk, ordinary matt emulsion or indeed one of any number of paints currently on the market.
