Introduction
Wood structures like timber decks and verandahs face harsh and constantly changing environments. Humidity, rainwater, and sunlight are the environmental factors that affect your deck floors. Deck and Verandah floor sanding is an essential part of home maintenance.
Timber decking is a popular choice for the outdoor living areas of Brisbane homes. Brisbane’s weather allows you to have comfy outdoor dining and solace, enjoying a cup of tea or having a small family gathering on your back deck. On the other hand, condition maintaining your timber deck is mandatory for all these activities. We recommend an annual coating to keep your timber deck shiny, and resilient whilst keeping away any excessive treatment procedures.
When do you need Timber Deck Sanding In Brisbane?
Your timber deck/verandah may need sanding and recoating if it starts to show any of the following signs of deterioration.
Deck Coating Starts to Peel
Deck coatings usually start to peel due to spillage or severe weather conditions. Unattended verandahs and closed homes are most likely to face such type of damage. Sanding a surface with a floor sander and polishing it is promising to give back the beautiful look of a timber deck and verandah.
The Timber Decking Boards Start to Turn Gray
Exposure to the sun’s UV rays causes photochemical degradation of wood, resulting in a change in the physical appearance of wood from natural brown to gray color. The effect can be reversed by opting for bleaching, scrubbing, pressure washing, or depending upon the extent of change with time.
Nails Start to Protrude Out of the Wooden Boards
The popping-out of the nail from the wooden surface sometime after it has been originally based is due to shrinkage of the wooden fibers around the nails causing its protrusion. Hammering it or cutting it with a multi-purpose tool followed by sanding timber decks is the most appropriate procedure to get rid of such a situation.
Timber Deck and Verandah Restoration Process
The purpose of timber decks and verandahs is multi-fold. It adds beauty and value to your home and is also a place for a family congregation. To maintain and extend the life of decks, it is important to take good care of them by following some simple steps that we undergo while providing our services.
Choosing the Right Sander
The three types of sanders are drum, orbital, and edge sanders. Usually, the decks and verandahs in Brisbane are jarrahs, spotted gum, and merbau. These woods are sturdy, durable, and challenging to sand. Choosing the right equipment for sanding saves time and brings the best results.
Sanding Grit Progression
At the beginning of the sanding process, the orbital or drum sander is fixed with a coarse grit sandpaper (around 40-60 grit) to remove the hard-to-remove old finish and weathered timber. Coarser grits and sandpapers remove material from the worn-out floors faster but can leave scratches on the floor. Switch the sandpaper progressively to a finer grit (up to 120) for a smoother finish. You can have a more polished and smoother surface from fine-grit sandpaper.
Sanding Technique
For edges or areas that are hard to reach, a handheld orbital sander or sanding block is recommended for achieving a smooth surface. To prevent scratches, always sand in the direction of the wood grain. Maintain a consistent motion with the sander to avoid damaging the timber.
Dust Collection
Wear a proper uniform to avoid dust getting into your eyes or bruising your hands. Equipment with a dust collection system( an orbital sander with a dust bag attached) prevents dust accumulation in the room or nearby furniture and household items.
Damages Inspection
The first and foremost process before carrying out any treatment is to inspect the damages being done to the deck due to humidity, weather, UV rays, or any other cause. Our team carefully surveys the area and does the proper homework before starting the next step.
Cleaning
Followed by the detection of damages the next step is cleaning the area with pressure machines and specialized equipment. The best cleaner for this procedure is Sikkens Cetol BL deck and wood cleaner. If the deck has been previously painted then we opt for paint removal procedures first.
Sanding
The most important step in deck sanding in Brisbane using tools that even out rough surfaces removing all kinds of impurities and making it smooth and applicable for finishing treatments.
Polishing and Finishing
The last step is the polishing of the timber deck with decking oils. Above all the products used for this purpose, or recommended ones are Sikkens products which are applied as follows:
- Sikkens Cetol HLSE is applied which comes in different colors providing a beautiful finish. It is microporous so allows the timber to breathe and it also provides resistance to extreme weather conditions and UV rays exposure on sunny days.
- Sikkens Cetol deck is applied afterward as two coats. It is transparent and oil-based and provides additional protection and finishing.
After all these steps your beautiful deck and verandah get ready after 2 days of drying time. For maintaining your homes, it is necessary to have an annual follow-up to keep them in good condition.
