WALL PAINTING TIPS AND TRICKS
TO AVOID LAP MARKS
Lap marks are ugly stripes caused by uneven layers of paint buildup. This usually happen when you roll over paint that is already partly dry. The best way to avoiding lap marks is to maintain a wet edge so that each stroke of your roller can overlap the previous stroke before the paint begins to dry.
In order to maintain a wet edge, start at a corner and then run the roller up and down the full height of the wall, making sure to move over slightly with each stroke. Wherever necessary, move backward to even out thick spots or runs. Do not let the roller become nearly dry before reloading it. Do this often so that it is always at least half loaded. Also, make sure the open side of the roller frame is facing the area that is already painted as this puts less pressure on the open side of the roller, thereby, making it less likely for you to leave paint ridges
Paint color can vary slightly from one can to the next. If you open a new can in the middle of a wall, you can notice the difference. Mixing the paints together takes care of this problem. It is best to estimate the amount of paint you will need and then mix it in a 5-gallon bucket.
If you find it difficult to estimate coverage, add more paint rather than less because you can always pour the leftover paint back into cans. If the job is large, use the bucket and a roller screen instead of a roller tray. It is much faster to load your roller with the screen than to use a roller pan.
FOR A PERFECT EDGE
Once the paint is dry, you can not just pull the tape off the trim. Paint usually form a film between the wall and the tape, therefore removing the tape will tear pieces of dried paint off the wall. So, it is better to cut the tape loose before pulling it off.
You have to wait for the paint to completely dry, after which you will use a sharp utility knife to slice through the film. Start in an area that is not easily noticed so as to make sure the paint is hard enough to slice cleanly. You’ll make a mess if you cut the paint while it’s still gummy.
