How to create a Concrete Effect finish
Enjoy the refined modern industrial textural effect of polished concrete. Make a statement in your home on interior walls in the living room, bedroom, or study.
Before you get started, make sure you’ve got the following things on hand:
- Dulux Design Concrete Effect paint
- Quality masking tape
- A paint stirrer and drop sheet
- Long nap roller, roller tray and a 100mm paint brush
- Steel trowel
- 600 grit sandpaper
- Carefully read and follow the instructions on the product label before you begin.
- Mask off the area with painters tape – where you don’t want any paint, such as adjacent walls.
- Stir the paint well with a paint stirrer using an up and down scooping action. Make sure you scrape the bottom of the can to ensure particles are evenly distributed.
- Practice your application technique on a large, spare piece of board.
- Work in small sections. Use a long nap roller to apply to the wall.
- Smooth the surface with a steel trowel with broad, sweeping strokes, holding the trowel at a 60° to 80° angle. Be sure to keep the working edge of the trowel clean by wiping paint build up with a damp cloth.
- Repeat this process over the entire wall, overlapping sections as you go. Allow at least 2 hours between coats.
- Apply 3 coats using the same process.
- Allow final coat to dry for at least 2 hours, no longer than 24 hours, before polishing.
- Using 600 grit sandpaper, lightly polish the surface in a circular motion.
- Use the edge of the trowel to further polish the surface. Apply enough pressure to keep the trowel edge flat against the surface. Be careful not to gouge the surface with the edge of the trowel.
- Dust the surface with a soft cloth to remove the sanding residue.
The more you polish the final coat, the more depth of colour you will see.
For a more textured effect, don’t completely smooth the surface – leave imperfections.
For further protection, seal with one coat of Berger® Jet Dry® Stone & Paving Sealer in Natural finish mixed with water at a 1:1 ratio.
