How to paint rendered walls

A rendered wall can add a wonderful touch of texture to any space. Though, of course, unpainted concrete mightn’t be the look you’re after. Is there a difference between painting a rendered wall, and any other? A little more prep, perhaps. But with our guide, adding a splash of colour is as simple and straightforward as can be.

Step One: Render Preparation

• Clean surrounding area, then remove dirt or flaking paint from the wall using a high pressure hose.
• Give the wall a final brush to remove any missed dirt, dust or cobwebs.
• Tape areas you don’t want painted and lay drop sheets where required.

Step Two: paint Preparation

• Stir your paint with a flat stirrer.
• If you don’t have a paint stirrer, use an old ruler.

Step Three: Application

• Begin by cutting in with a brush. This means painting the edges first and then moving in. Start at the top, then bottom and go around any edges or features.
• Keep a wet edge by not cutting in too early before using the roller.

• We recommend painting in weather between 10–30°C.

• Once you’ve finished cutting in, start painting with the roller.
• Load the roller by dipping it in the paint. Make sure you have an even cover of paint around the roller sleeve before you begin.

• If your roller doesn’t spin evenly, the paint is uneven and you need to load up again.

• Start rolling in an M pattern moving from one side of the wall to the other. Never start in the middle

• Use a roller pole to reach further with each stroke.Because of the difference in finish between brush and roller, get as close as you can to where you cut in.

• Load up your roller more often so you don’t have to work as hard.

• Each time you finish a three to four metre section you need to lay off your paint.
• Do this by rolling the roller without loading it up with paint. Then roll from the top of the wall to the bottom in one straight stroke.
• Continue along the length of the painted wall taking care to slightly overlap so you don’t cause streaks.
• It’s important you maintain a wet edge and complete an entire section of wall before stopping so your finish isn’t patchy.
• If the edge dries, it may create a line in your finish.
• Allow at least two hours drying time before applying a second coat.
