How to render corners
How to render corners
Overview
Before you can render a brick wall, you need to prepare the external corners with angle beads. These not only give you a cleaner finish but also provide strength and prevent chipping. We'll show you the simple steps you need to follow to prepare external corners for rendering.
Steps
Clean and measure the wall
Before you start, make sure the surfaces of the external corners are clean. Measure the height of the external wall and if there are any windows, their height and length as well. These are the measurements you'll use to cut your angle bead.
Cut the angle bead to length
Transfer the measurements to the angle bead and cut it using your snips. In this case we've cut two for the reveals and one for the sill. When you're cutting the angle bead, cut it on a back angle so that the edges don't catch on the brickwork or the eaves.
Mix up the adhesive
Put on your gloves, safety glasses and dust mask, then pour some water into your mixing bucket. Add the Patch and Prep adhesive. Mix it with your trowel until it is the same consistency as toothpaste. If it is too runny add more adhesive, if it is too dry add more water.
Apply the adhesive to the corners
When applying the adhesive you want it 2mm thick and 25mm wide, either side of the corner. Applying the adhesive is the same as applying render, just flip the hawk onto the trowel to pick up the adhesive and using your ladder, apply it from the top of the wall to the bottom.
Fix the angle bead to the corner
To fix the angle bead to the corner, push it into the bed of adhesive. Use a slight up and down motion to help it sink into the adhesive. Push your straight edge, hard up against the angle bead, to make sure there aren't any hollows or bumps in the bead.
Remove the excess adhesive with a trowel
Leave it to dry for five minutes. Then use your trowel to remove the excess adhesive down the bead. Flatten off the excess by angling the trowel slightly and pushing the adhesive away from the bead. Do this on both sides of the bead from top to bottom.
Apply the adhesive and beads around the window
Apply a 2mm thick and 25mm wide layer of adhesive around the corners of the window ledge. Follow the same process as you did on the corners. Make sure that the beads are at right angles in all of the corners of your window. Then let the adhesive dry for five minutes and use your trowel to smooth off the excess adhesive as before. Leave for 24 hours to dry completely.

Health & Safety
Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.
Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer.
