Ok, you decided to give a new layer of paint to some of your rooms, yay! But then you realize you are not a professional painter and then you have to deal with problems. Many painting problems can be addressed in an easy way so, this is a list of three common problems you may encounter and the best way to fix or, even better, prevent them so you won’t have to deal with them.
A very annoying problem is to have filler showing though. Of course, if you have filler showing through, you must hide it but first, let’s see why did this happen in the first place. If you fill areas before you paint, you should prime. Yes, many paints say you don’t need to prime but, if you are filling, you need to prime if you don’t want to have this problem. The best way then, is to prime it well and then you won’t have to fix it but, if it is too late already and you must heal instead of preventing, recoat the filler with some primer. If you are using latex paint instead of oil or water-based one, you may prime it with paint itself. Unfortunately, after this you will have to recoat the entire wall if you don’t want the patch to be shown.
If you are painting wood (see a wide selection of wood blinds at OzBlinds.com.au), you may have to deal with bleeding knots. Wood has natural knots and, if they haven’t been properly knotted and then primed, they may continue to secrete resin and this may show through many layers of paint, maybe you can’t deal with this by painting over and over again. The best way to fix this problem is to sand the paint over the knot area and then sand the area again to make it as smooth as possible. Apply sealer to the knot, ensuring you cover it completely and then apply primer over the sealer. Let it dry properly and then paint again.
Uneven distribution and roller marks are something you may have to deal with as well. These are pretty easy to prevent, the only thing you have to do is to paint the area in the same direction at all times and not change it. Since you are using a roller, the most usual way is from down to top and then from top to down, but try to do it as straight as possible so you won’t have to deal with uneven surfaces. Do not apply too much pressure to the roller, this won’t make the paint to attach better to the wall, instead it will disperse the paint to the edges of the roller. If this happens, the area you paint with the edges of the roller will have a paint overload while the center of it will have a lack, leading to unevenness. If your paint is dry already and you have this unevenness, you’ll have to paint it again, sorry.
