How to Prepare and Paint Your Deck: The Ultimate Guide

1 Your decking timber should be free from dust, dirt, mildew, algae and other contaminants. That’s why we always recommend that you use a suitable cleaner before you paint.

2. Decking cleaners are specially formulated to clean and revive weathered or tired looking deck boards, they remove moss, mould, algae and prepare the surface for your coating. We recommend Farbex Multi-Surface Cleaner as your decking cleaner (refer to manufactures instructions on how to use)

3. If your deck has any nail holes or cracks always fill these with suitable External Timber filler. We recommend Prestonette and Osmo Exterior wood fillers.

4. We recommend using either Sikkens HLS or Ronseal Decking Oil/Stains for your deck.

5. Always use a high quality applicator when coating your deck, we recommend a 3” or 4” Brush either by Wooster, Corona, or Harper and Green. Refer to manufactures guide if you can use a Roller as some brands need to be applied by brush only.

6. With all your preparation work done, start at the far end of your deck and apply your coating one/two boards at a time in the direction of the wood grain.

7. Apply your product in long, smooth strokes and always coat end to end – never stop half way through to start the next board(s) as you will get a uneven finish.

8. Most new decks will require two/three coats, a previously coated deck one/two. Always refer to manufactures instructions to find out the required drying time between coats.
