To prevent air from entering partially used paint cans, store them upside down after placing the top on firmly.
Always store paint in its original container, with the label intact. This will help you properly identify rise color and type of paint when you go to use it again. If key information is concealed by paint drippings, write down the brand, manufacturer’s code, color, gloss level and type of paint on a strip of masking tape and affix it to the side of the can before you put it away.
Paint walls from the top down. If you are using a roller, start by making a large "V" or "W" (3'x3'). Then fill in between the gaps, blending into your initial stokes. Always work from the unpainted into the painted area.
For a quicker and more efficient paint job, don't overload the paintbrush or roller. If it drips, there's too much paint.
When using a paint pad, apply the paint with long, straight strokes, all in the same direction. Do not pull the pad back over the painted area. Also, be aware that paint pads have a tendency to leave lap marks if you do not feather the paint carefully where one stroke meets another.
Get the most out of your paint roller by cleaning and re-using it. After washing, hang the roller on a rope or dowel to dry, don't stand the roller on its end or lay it on it's nap. Dry thoroughly before storing in dust-free cabinets or boxes.
When painting a room which has surfaces that are in good shape, plan on spending about half as much time on preparation and clean-up as the actual painting. Where surfaces are in poor shape, non-painting time will increase accordingly, and may take more time than the paint application itself. To save time in cleaning up paint trays, either line them with aluminum foil before starting, or simply slip smaller trash bags over them.
If you want to re-use a roller cover on several paintjobs, it is best to start with the lightest color, then work in gradually darker colors, following each job with a thorough cleansing of the cover.
To make a room appear taller, paint the ceiling the same color as the walls. This eliminates any break between the two and gives the illusion of height.
Be sure that your first coat of paint is dry before applying a secpnd coat. Although latex paint will quickly feel dry to the touch, adhere to the specified drying times for the best results.
