Project Overview

Applying a tinted top coat to render saves you from having to paint, while making sure your surfaces are protected. We’ll show you how to use a premixed render that is available in a wide range of colours to suit your home. This is a simple job you can do with just a few tools and the help of a friend.

This D.I.Y. Advice is part of a series How to render

Step by Step Instructions

1 Mask off the surface with painter tape
2 Apply the top coat
3 Apply the render
4 Apply the finish to your wall
5 Remove tape to finish
  • Step 1. Mask off the surface with painter tape

    First you need to mask the borders of your surface with painters tape to protect the surrounding areas. In this case we masked off the flashing and neighbouring fence to make sure no product spills over.
  • Step 2. Apply the top coat

    Start by placing a suitable amount of product onto your hawk. Then get up on the scaffold and, using your trowel, start from the top of the wall and work your way down from the corner. Use a firm arching action to apply the product for the best result.

  • Step 3. Apply the render

    To get the render from your hawk onto the trowel, use a tipping motion and apply at a 30-degree angle. Apply a tight coat with a firm arcing action. Once you have enough on your wall, make sure you clean your tools as the product can dry onto these very quickly.  

  • Step 4. Apply the finish to your wall

    Use your plastic float to apply the finish in small circular motions. You might need a friend to help you for this step if it is over a large area. For large areas, keep a wet edge for a seamless finish. Avoid applying the product in direct sunlight as this it will set too hard.

  • Step 5. Remove tape to finish

    Allow the render to dry and harden, which usually takes 2-3 hours. Once the render has firmed up, all you need to do is remove the painter’s tape from around the surface and you’re done.
