TALKING TIMBER TALKING TIMBER • H4: Outside, in-ground use • H5: Outside, in-ground with freshwater contact • H6: Marine environment HANDLE WITH CARE “For the first year, the deck will have to be re-oiled every three months. If there is excessive rain, then this period may shorten to bi-monthly, as the oil will wash way quicker, since initially, the timber will not be saturated enough. The reason for oiling the deck and not varnishing it, is that varnish peels in the hot South African climate. This means that maintenance would become very costly, as the deck would have to be sanded and sealed on a regular basis,” advises Vermeulen. THE BEAUTY ROUTINE Once it is time to re-oil your deck, Vermeulen advises as follows: 1. Clean the deck (mop or hose down with Timberlife Deckwash). You may also use liquid turpentine to clean the deck, but this has to be soaked onto a cloth and wiped over the deck. 2. Let the deck dry 100%. 3. If there are small scratches or dirt which has adhered to the oil, take fine sandpaper and lightly sand these areas. 4. Sweep the deck clean of all dust. 5. Apply the oil with a brush, making sure that you do not overlap, as this will tend to leave marks on the deck. 6. Let it dry for at least 24 hours (best to wait 48 hours) before walking on it. 7. Use SATINWOODBASE 28, or any other decking oil. Five litres will be sufficient to cover one coat of 40m². Always use the same product for coating, as different products will not mix well. 8. Seal both sides before installation, and then brush another two coats on top. 9. After the first year, you will need to do this every 6 to 8 months, depending on the wear and tear of your deck. Falling to do so, will cause your timber to dry out, crack and turn grey. Some architects and clients request the silver-grey colour, which can be accomplished with time – but be careful of surface cracks due to dryness. THE MODELLING AGENT: IMPORTANT CONSIDERATIONS WHEN HIRING A TIMBER DECKING CONTRACTOR References are very important. Go and have a look at the contractor’s previous decks, and rather pay more for someone with more experience, says Vermeulen. Cheaper is not always better – you need someone who knows what they are doing and can add value to your property. Unfortunately, there are a lot of fly-by-night contractors that give the business a bad reputation. BEAUTY TIPS: ‘DOS AND DON’TS’ • Do keep up with the maintenance. It is easier to treat the wood on time, than to replace. • Do not use the non-slip groove to the top – as water lying in between the grooves reduces the life span of your deck. • Do make sure your substructure is based between 400mm – 450mm apart. • Do make sure the material is treated at the bottom as well as top. www.timberiq.co.za // APRIL / MAY 2020 35 // APRIL / MAY 2020 35
