How can I paint a ceiling without visible overlaps?
Painting a ceiling without leaving visible roller marks can be a challenge even for professional painters. Before starting, make sure the ambient humidity level is at 50%. If it is lower, the paint will dry too fast and the roller marks might appear. Here are some guidelines you can follow:
- Ideally, room temperature should be between 20ºC and 26ºC.
- Make an adequate surface preparation to remove any contaminants that may adversely affect the adhesion of the paint to the ceiling. Make sure to have a clean, dry surface before applying paint.
- If necessary, repair surface defects and sand lightly.
- Apply an appropriate primer for the surface, such as Acrylic Latex Plus 170 primer-sealer or Portico 100% Acrylic 270 undercoat.
- Use Absolute Flat 1670 ultra flat finish ceiling paint.
- Using a paintbrush, paint all the corners of the room.
- Use a 15mm lint-free quality roller. Starting in one corner and moving from wall to wall, apply one roller width of paint at a time without pausing. Generously apply paint, without spreading it too thin.
- Avoid painting over freshly painted areas.
- Create a narrow joint between two adjoining ceilings.
- Respect the recommended drying time between coats.
- Before making a final evaluation, let dry for at least 24 hours for light colours and 72 hours for dark colours.
To extend drying time, close all doors and windows during application.
