DIY Advice – Preparing Your Walls For Painting

It’s Time To Paint – Preparing Your Walls 

Taking time to paint the exterior walls of your home will not only enhance its look, it can also help you protect your home walls against weather damage. Preparing your wall is key to ensure that you get the best out of your project. Here are a few items that you are going to need:

Shave’s Shopping List

  • Hand brush (med/hard bristles)
  • Scrapper
  • Fungiwash
  • Exterior crack filler
  • Scrapper medium grit
  • Primer
  • Exterior paint (Ultradek/Dekatex)

Preparations before applying your chosen colour.

Use a medium to stiff bristled hand brush to remove any surface dirt and loose paint. Use a scraper to remove any loose masonry.

If the wall is very dirty wash the wall with household detergent and rinse well with water. Problem areas affected by mould, algae or climbers should be thoroughly cleaned and treated with a fungicidal wash. Always read the instructions of the product prior to use.

Fill small cracks and holes, firstly make sure the damaged area is free from loose materials. Then apply the exterior filler or mortar using a knife and smooth off with a wet filling knife.

If the crack or damage is deeper than 10mm, you may have to build up the filler in layers, leaving each layer to dry before applications.

Rub down with medium grade sandpaper when dry.

Seal and prime porous or powdery surfaces with a masonry primer using a small paint brush for edges and hard to reach areas. Use a medium or long pile roller for larger areas, this will create a stable surface for painting and make it easier to apply paint and make it go further.

Paint your desired colour ensuring you paint in one direction to create an even finish.

Tips – Different finishes available: smooth vs textured

Smooth Paint (Ultradex) – This gives a nice even finish. It can disguise minor blemishes and is easy to apply.

Textured paint (Dekatex) – fine textured exterior wall for extra body and flexibility.

When deciding on a colour, pick up some tester pots and paint, available at all our Shave stores, onto cardboard or plasterboard. This will give you an idea of how it will look. Don’t forget – the colour will look different depending on the time of day and which way the wall is facing.
