Deck Sanding in Newcastle
Taking Back the Weathered Layer
Once a deck's coating gives out, UV and rain get straight into the timber and it greys, roughens and starts throwing splinters. The timber underneath is usually still good. At Freedom Flooring, deck sanding in Newcastle takes off that weathered surface layer, opens the grain back up so a new finish can penetrate, and gets the boards flat and safe underfoot again. Protruding nails and screws are punched or reset first, and the whole deck is resealed with an exterior-grade product built for coastal exposure. Where boards are split or rotted beyond sanding, board replacement happens during the same visit. Call 0404 606 142 for a free measure.
Restoring an Outdoor Timber Deck
Exterior timber is a different problem to interior flooring, and the finish has to be chosen for movement rather than hardness.
Fixings are checked and reset before sanding starts. A single proud screw head will destroy an abrasive belt and gouge the board around it, so the whole deck is walked and punched first.
The grey surface layer is sanded off to expose sound timber. Greying is UV damage to the outer fibres, and a coating applied over it sits on a weak layer that lifts with those fibres.
Split, cupped or rotted boards are replaced during the same visit. Boards near the perimeter and around posts tend to go first, since that's where water sits longest after rain.
Exterior finishes are chosen for flexibility and UV resistance rather than hardness. Decks expand, contract and take direct sun, so a hard interior-style coating cracks and peels where an oil or purpose-made exterior product won't.
FAQs
- A full sand is only needed once the finish has broken down and the timber has started to grey or roughen. Recoating regularly before that point extends the interval considerably, so frequency depends more on maintenance than on age.
- Ultraviolet light breaks down lignin, the compound binding timber fibres together, and rain washes the degraded material away. What's left is a thin layer of loose grey fibres on the surface, which sands off to reveal sound timber beneath.
- Penetrating oils soak into the timber, wear gradually and are simple to top up without stripping. Film-forming coatings give a harder surface but need sanding back once they crack or peel, so the trade-off is between ongoing upkeep and longer intervals.
