Care Guide

– Use the recommended cleaner to remove dirt, stains, or residues. Always allow the surface to dry fully before applying any product.
– Use a foam brush, applicator pad, or polishing machine depending on the product type. Apply 1–2 thin coats as directed, allowing proper drying time in between.
– Reapply every 3–12 months depending on exposure to sunlight, moisture, or wear. Avoid harsh chemicals or abrasive tools that could damage the finish.
– Always test on a small hidden area first. Choose the product finish (matte, gloss, satin) that suits your surface and style.

Description Teak Sealer Coverage

Restore to a Rich, Sandy-Tan Finish with Semco Natural Teak Sealer

Achieve the iconic "sandy tan" look of professional marine decks with Semco Natural Teak Sealer. It’s the industry favorite for a clean, weathered-yet-refined finish without the greasy residue of traditional oils.

Semco Stands Out As the Best Teak Sealer

✅ The Finish: Eliminates dull grey and replaces it with a rich, water-resistant "sandy tan" glow.

✅ Non-Oily: Unlike other brands, Semco dries to a clean timber feeling finish that won't attract dirt or feel slippery.

✅ Long Lasting: Lasts through the season and can be renewed without deep cleaning or stripping for years!

✅ Simple Maintenance: Apply in minutes; no professional tools required.

✅ Semi-Permanent: Semco is long lasting but if you want to change your look, the Semco 2-Part Cleaning Kit removes the sealer easily - no sanding needed.

If your teak is in a high-exposure environment, reapply Semco Teak Sealer every three to six months. It can be reapplied straight over the top of previous coats.
