How to Render a Wall

 

If you want to change the look and texture of a wall but don't want to paint it, you can render it instead. Wall rendering is the process of adhering a mixture of wet cement and sand to a wall with a trowel. Rendering gives the wall a solid cement look and can be used to cover up the existing wall material. If you follow the right procedures and use the right materials, you can render a wall yourself.

1

Chip away any old render and paint. Use a cold chisel that is just sharp enough to scrape, chip away any bumps, dripping render, paint, or mortar that's stuck to the wall. Sometimes the old render may flake off and you'll want to scrape it all away before applying the new render. Continue to chip away at the wall until the stone or brickwork is free of bumps.^[1]

2

Scrub down the wall with a stiff bristled broom. Work the broom over the surface of the wall, making sure to displace any dirt or debris that may be on it. Work away any organic material, like moss or mold, that may be growing on the wall. Continue to work the broom back and forth against the wall until it's clean.^[2] You can also add some soap to help break up the material.

3

Spray the wall down with a hose. Use a garden hose and spray down the surface of your wall. This will prevent the water in your rendering mortar from drying out. This is especially important when rendering highly porous materials like sandstone.^[3]

4

Lay down drop cloths around the wall. Drop cloths will prevent dripping render from falling and hardening onto the ground near the wall. Tape the drop cloths to the ground with tape so that it doesn't move around as you work. Laying down drop cloths will prevent you from having to chip away dripping render later.^[4]

·       If you don't have drop cloths you can use tarps, cardboard, or garbage bags.
