Sealers
Applying a quality deck sealer is one of the most effective ways to preserve a teak deck's appearance and slow the rate of surface weathering. TDS Teak Sealer & Protector is a water-based penetrating formula that maintains the wood's warm, golden colour while providing UV protection — without forming a surface film or requiring removal from caulk seams before re-application.
TDS Composite Sealer is a dedicated formula for TDS CompositeDeck and comparable synthetic deck surfaces. It delivers deep-penetrating UV resistance and a hydrophobic barrier without VOCs, and is designed for simple seasonal application by boat owners and professional crews alike.
For best results, apply sealer to a clean, dry deck — use TDS ECO-100 or ECO-300 first to remove salt, grime, and prior sealer residue. Frequency of sealer application depends on sun exposure and climate; TDS recommends inspecting your deck seasonally and re-sealing as soon as the surface begins to show UV graying.
Teak Sealer & Protector
Easy to apply water-based formulation that penetrates the wood grain. Provides UV and weather protection without changing the natural color of teak. Does not need to be wiped from caulk seams.
Composite Sealer
Deep-penetrating alkali-resistant hydrophobic barrier for composite decks. Contains no VOCs, will not yellow over time, and prevents stains, UV damage, and weathering.
Common Questions
Teak Sealers FAQ
Does a teak deck need to be sealed?
Sealing is optional, not mandatory. Some owners prefer to let teak weather naturally to a silver-grey patina. Sealing with TDS Teak Sealer & Protector helps maintain the wood's golden colour, provides UV protection, and reduces the rate of surface weathering — particularly in high-UV environments.
What is the difference between the Teak Sealer and the Composite Sealer?
TDS Teak Sealer & Protector is formulated for natural teak wood — it penetrates the grain and does not need to be wiped from caulk seams. The Composite Sealer is formulated specifically for TDS CompositeDeck and similar composite surfaces, providing UV protection suited to composite materials.
How often should I apply teak sealer?
Typically once or twice a year depending on UV exposure and usage. Teak in high-sun climates (Mediterranean, Caribbean, Florida) may benefit from two applications per season. Apply to a clean, dry surface for best results.
Will sealer change the colour of my teak?
TDS Teak Sealer & Protector is designed to maintain the natural colour of teak without creating a dark or shiny finish. It penetrates the grain rather than sitting on the surface. Apply a test patch on an inconspicuous area if you want to check the result before treating the full deck.
Can I apply sealer over caulk seams?
Yes. TDS Teak Sealer & Protector does not need to be masked off or wiped from the caulk seams during application, which simplifies the process and prevents drip marks on the seam edges.
