What's the best way to get a clean line between the wall and the ceiling when painting a room?

The secret to getting a crisp, professional-looking line between the wall and ceiling is in the preparation and technique. Use a high-quality painter's tape along the ceiling edge to create a sharp line, sealing the tape by painting over it with the ceiling color first. Wait for it to dry, and then paint your wall, removing the tape while the paint is still slightly wet for a clean edge. Use an angled sash brush to cut-in by hand, being careful not to overload the brush with excess paint that can cause drips and uneven lines.

Can you wait too long to paint after priming?

You always want to paint as soon as possible after priming. The primer needs time to dry, usually from a few hours to a whole day, but dust, dirt, or oils can settle if left for too long, reducing the adhesion and the primer's main purpose. Some primers can absorb moisture or harden over time, making them less effective. As a rule of thumb, paint within 24 to 72 hours for latex and water-based primers, and up to a week for an oil-based primer.

What is paint primer used for?

Paint primer preps your surfaces before painting, creating a consistent base that helps your paint stick better, go on smoother, show more color, and last longer. We stock a wide range of primer for all types of purposes, including difficult surfaces, sealant, or odor blocking.

What primer can I use on top of paint?

The right primer to use on top of paint depends on a few factors. Select a bonding primer for previously painted cabinets, trim, or furniture, and a latex or water-based primer on walls with flat or matte paint. For specialty projects, you can use an oil-based primer when switching from oil-based to latex paint, or a stain-blocking primer if the old paint has stains, smoke damage, or strong colors you need to cover.
