At Pat McDonnell Paints, we get many questions around this time of year on how to breathe new life into old decking. If you have decided that it’s time to spruce up your deck, check out our handy step-by-step guide below.
Why does decking need maintenance?
Decking is a fantastic addition to any garden, providing a great spot for relaxing, entertaining, or enjoying a Sunday morning coffee. However, the Irish climate can be tough on wood. Constant exposure to moisture can lead to mould, algae, and general weathering, while UV rays from the sun (when we get them! ) can cause fading and cracking over time. Regular maintenance helps to protect your decking, keeping it looking good and extending its lifespan.
Before you start
Check the forecast as you will need a few days of dry weather to complete your project. Avoid very hot weather as this may cause the product to dry too quickly and not fully absorb into the wood.
Step 1: Preparation
Cleaning is key to a successful decking makeover. Start by removing all furniture, plants and decorations. Then thoroughly sweep the deck with a hard-bristled yard brush to remove surface debris and dislodge some of the growth (moss, algae, mildew etc ) that you will inevitably find on an Irish deck.
Use a hose with a nozzle to rinse away stubborn dirt. If you prefer, a power washer can do the job too — just be sure to take precautions to protect the timber. Keep the nozzle at a safe distance from the surface and opt for a wide fan tip rather than a pointed one to avoid damage.
Tip: Don’t use bleach cleaner, as this can whiten and damage your decking boards.
If required, sand off any loose or flaking areas. Run a cloth soaked in white spirits over the decking boards to remove any sanding dust.
Leave the decking to dry for at least two days. While the decking may seem dry the day after, you risk sealing in any remaining moisture which can lead to cracking and splitting.
What’s more, you risk sealing moisture within the wood and in time, this will push any coating you apply off your deck.
Step 2: Choose the correct product
For a bold, opaque finish in a solid colour that covers the wood grain, explore decking paints from Ronseal which are available in a variety of colours. If you prefer a more natural look, stains from Cuprinol, Ronseal, and Sikkens add colour while keeping the grain visible. For hard-wearing protection and a natural finish, we recommend a decking oil from Osmo or Ronseal.
If you are refinishing an existing deck, we recommend sticking with the same product type previously used for ease of application. This is the most straightforward option. If you want to change product completely, it’s best to speak with a member of our team who can advise you on the best options for your deck.
Sikkens HLS is my go-to product if you are looking for a stain or a solid colour.
Step 3: Time to paint/stain/oil your decking
Whatever product you opt for, always follow the manufacturer’s instructions for application tips.
Using a good quality paint brush (approx. 3 - 4” in width ), apply the decking oil along the decking boards – always with the grain.
Tip: For an even finish, start at the furthest end of the deck and go in an S-shape, painting one or two boards at a time.
We recommend applying two coats. After your final coat, leave at least 24 hours of good weather before you use it.
Now, time to put your feet up and enjoy your newly refreshed deck!
Step 4: Aftercare
At the end of September, give your decking a third coat to protect it from the winter weather.
