How to choose a paint roller?Oct 13, 2016
There are many paint rollers in the market, I will tell you 5 steps to choose a high quality paint roller.
Start with a good roller pin.
To extend your reach and give you better control, screw a 48 inch (1.2 meter) wood handle or extension pole onto the end of the roller.
Invest in a good roller cover (also known as a sleeve). It’s tempting to buy the cheapest cover available and throw it away when you’re done, but cheap roller covers don’t hold enough paint to do a good job. It'll take you twice as long to paint a room and the results won't be as good. Use a 1/2 inch (1.2 cm) nap for flat paint on walls and ceilings, 3/4 inch (1.9 cm) nap for rough surfaces like textured ceilings, and 1/4 inch (.63 cm) nap for satin or semi-gloss paint. See the Tips below for more information on how to take good care of your equipment.
You'll rarely see a pro using a paint tray for painting very large areas. A 5-gallon (18.9 liter) bucket with a special bucket screen hung over the edge works better because it's easier to load the cover, it's easier to move around, and you're less likely to trip over it or step in it. And if you need to take a break, you can just cover it with a damp towel to keep the paint from drying.
Roller trays work well for smaller areas such as bedrooms where a single gallon of paint might be all that is needed. Cleanup is also easier with roller trays. Add a tray liner to make cleanup even easier.
