Heavy rain and strong coastal wind can leave a timber deck looking tired very quickly. On the west coast of Mauritius, Tamarin villas, Tamarina Golf Estate homes and resort terraces may be exposed to driving rain, wind-blown grit, damp leaves and long periods of humidity. Sanding can restore a sound hardwood surface, but only when the deck is dry and the preparation is done carefully.
Wait for the timber to dry properly
Do not sand immediately after a storm. Water held inside the boards can clog abrasive paper, create a rough finish and trap moisture below a new coating. Clear leaves and standing water first, then allow several consecutive dry days with good airflow. A shaded deck may take longer than an exposed one. The surface should feel dry and show no dark, damp patches before work begins.
Inspect before you sand
Sanding is a surface repair, not a solution for structural damage. Check for soft spots, lifted boards, loose screws, cracked ends, failed joists and movement underfoot. Pay special attention around pool edges, planters and steps where water remains longer. Replace or secure damaged boards before sanding, otherwise the finished surface will quickly deteriorate again.
Practical tip: Sweep out the board gaps before sanding. Packed leaves and sand hold moisture against the timber and can also damage sanding equipment.
Use a gradual sanding sequence
Start with the least aggressive abrasive that will remove the grey fibres and remaining coating. A typical hardwood deck may need a coarse pass only where the surface is badly weathered, followed by medium and fine passes to remove scratches. Work along the grain and keep the machine moving so you do not create dips or swirl marks. Edges, corners and steps usually need careful hand sanding.
Remove dust between stages with a vacuum or soft broom. Avoid blasting a timber deck with a high-pressure washer immediately before sanding: it can drive water deep into the grain and raise the fibres unevenly. If washing is necessary, use a controlled low-pressure clean and wait until the boards are fully dry.
Plan around the west coast climate
For a Tamarin property, plan the job around the weather rather than a fixed calendar date. A morning start gives the deck time to warm and dry, while a late-afternoon coating can leave the surface vulnerable to overnight dew. Keep furniture, rugs and pots off the boards while they cure. On resort terraces, cordon off the work area and check that guests will not track grit across the freshly prepared timber.
Recoat at the right time
After the final sanding, inspect the surface in daylight and remove all dust. Apply a suitable exterior deck oil or coating according to the product instructions, working in manageable sections. Avoid the hottest part of the day and do not coat if rain is likely before the product has cured. Tamarin's salt air and intense sun mean that exposed decks often need more frequent inspection than sheltered inland timber.
