Painting a Shed or Log Cabin - Preparation Top Tips!

Remove any dirt, mildew, moss, or ivy with a cleaner such as methylated spirit and allow to dry. 

Sand down your shed to remove rough surfaces and remove any loose material with a stiff brush. Use Oakey Liberty Green Sandpaper in P120

Remove any dust from sanding with a tack cloth or brush.

Fill any minor holes and imperfections with a good quality wood filler which is as close to the colour of the timber as possible. Top tip – if your finish is translucent, avoid filling large areas as they may be visible through the coating.

Sand to blend with the surrounding timber and remove any dust as before.

If you’re using an oil-based paint system, you will need to apply knotting solution such as Rustins White Knotting to any knots in the timber. Top tip – if you are using a water-based product, you do not need to use knotting solution.

Give the paint a good mix before and during the process to make sure you get a consistent sheen and colour. You will need to apply the paint in dry conditions with a temperature above 10 degrees. 

When painting, don’t forget to paint end grains, tops and bottoms of doors and undersides of sills as they are easily missed!
