Use Universal Undercoat
Roof leaks can leave ugly ceiling stains, or dinginess that is impossible to conceal with just paint. By using Panache universal undercoat, it contains high hiding additives and with this your troubles are over.
Do remember, if your entire ceiling has gone yellow, it would be preferred to paint the whole ceiling with Panache universal undercoat before painting your ceiling with an acrylic.
Cut in Before You Roll
Cutting in before you roll allows you to cover most of the brush marks with the roller. Carefully brush paint along the edge of the ceiling a section at a time, this will remain wet until you roll, so it blends in better. This would minimize picture framing around the edges after rolling.
Roll Both Directions
There are a few ways in getting a smooth, consistent coat of paint on the ceiling. Work in sections about 2 squares at a time. Move quickly from one section to the next to make sure the paint along the edge doesn’t dry before you roll the adjoining section. This is called “keeping a wet edge” and is the key to avoiding lap marks. Do remember to move both directions.
Use the correct tools
When it comes to painting a ceiling, your aim is to get as much paint on the ceiling as you can in the shortest amount of time possible, while minimizing spatters. Being able to do this, you would require the best roller for the job. We recommend you using Lambs wool.
Use a matt acrylic
With ceilings, we have found that when painted with a sheen acrylic, you have a reflection of the light, and so it makes all imperfections stand out. When you paint with a matt, there is no reflection, and thus giving you a smooth finish.
