How to paint
The first thing you need to do when starting your deck restoration is a water bead test. Water soaking into your timber means that decking oil and stain should do the same.
To do this, splash some water on your deck and see if the water beads or absorbs into the timber. If the water beads, then further preparation, sanding, stripping or weathering is required.
When the water absorbs into the timber, you're ready for the next step.
Before you apply any oil or stain to your deck, you need to prepare the timber.
This can be done with an oxalic acid-based cleaner, such as Intergrain Reviva, which will bring the timber back to a natural colour while removing any denaturing or light stains.
Also make sure you hose down any plants near your deck before and after using the cleaner to minimise any damage to leaves.
Once your deck is dry, you're ready to apply the oil.
If you use Intergrain UltraDeck, 2 coats should be used for undercover areas and 3 coats for areas in direct exposure to the elements.
Having the right coverage rate is important to ensure the durability and longevity of your coating.
Follow the example below to work out how much Intergrain UltraDeck you'll need.
UltraDeck coverage = 12m2 per litre (on average)
6m (L) x 4m (W) deck = 24m2
Therefore, you'd need 4L of UltraDeck to cover your 24m2 deck with 2 coats
