Rollers for Paint
If you are planning to paint large surface like the ceiling your ideal choice should be the rollers. Their flexibility makes them simple to use and get done in no time. Rollers come in all shapes, size, and texture, like:
- Long pile
- Medium pile.
The paint that you use defines what type of rollers you would need to use. Let’s say for today’s job normal latex paint is your choice, for this; it would be best NOT to go with a foam/sponge roller, these can cause bubbles resulting in orange peel.
The major problem you would face if you use alkyd finishes on even areas will be the fiber and lint remains from the roller which can end up on your painted surface. But there is a solution, using a used latex painter’s roller brush that has been cleaned properly by the spinner. This will surely save you from the fiber shredding of the roller. If you have a new roller, then before using it, just dry it out after dipping it in clear spirit minerals.
Deep Pile Rollers
For a smooth surface, it is best to use deep pile rollers as they use less amount of paint. To make a surface texture prominent use a long pile. You can have great covering up at the highest point of the paint, however not at the base, in addition to you wind up with an uneven surface. You would get better results through a semi-dry roller or a denser shorter pile, but it will require more paint. It is advised to do double layers do paint.
A wall that has been painted many times with a roller develops a surface texture or “orange peel”. When a surface like this is patched, and the patches are sanded smooth prior to repainting, the patches should be “stippled” when they are spot primed or they will be quite visible under the new topcoat. Stippling can be done by using the end of a brush with a dabbing techniqe.
Rerolling a surface before the first layer paint dry’s is a simple technique of back rolling. For a typical alkyd paint the window for back rolling is 30 minutes under 20ºC (70ºF), after this, the paint is dried out which will not allow even leveling and proper flow. For latex paint the window is much smaller, estimated time 5minutes or less, causing poor leveling and flow properties. If you roller over a surface with dried latex paint, you will be left with a poor rough surface, giving an uneven look at the end of the job. The professional technique is, apply the prior coat with airless spray and then instantly perform back rolling.
