A rubber band can help waste less paint
If your walls are looking dingy and outdated, you may want to consider undertaking your own DIY project. Re-painting the rooms will give them a fresh feeling and will give you those house-flipping vibes you may be looking for. The best part is that you can do it yourself. Here is a handy hack to make sure you get no drip marks.
Brushes normally suck up more product than is necessary. If you do not get rid of the excess, you can end up with drip marks that will ruin your brand new paint job. Putting a large rubber band around the can will serve to eliminate any unnecessary paint. Just pass the brush through the band before you use it on the wall.
