Product Description

Premium oil-based translucent stain for timber decks, steps & walkways. This one-pot low-build coating absorbs deeply into the timber and provides extreme UV and weather protection. Cetol® Deck Ultra is a microporous coating that allows the timber to breathe whilst repelling unwanted moisture. Its luxurious translucent satin finish enhances the natural beauty of timber.

Application Description

Ready to use with no need to thin. Stir thoroughly before use. Final colour will depend upon timber type, previous treatment and the number of coats applied. Ensure timber moisture content is below 15%. Do not apply in temperatures below 5℃ and above 35°C, in damp conditions (when relative humidity is above 85%), or if rain or dew is likely before the product has dried. If using more than one can, it is advisable to mix them together in a larger container or finish in a corner before starting the new can to ensure colour consistency. On previously stained timber, touch up bare areas first and allow to dry. Avoid heavy wear and tear on the decking for a few days after application. At temperatures below 10°C and when used internally with limited air circulation, the drying process will be delayed. On correctly prepared surfaces, three coats evenly with a good quality brush along the grain, avoiding overlaps. Allow a minimum of 12 hours between coats.

Tips & Advice

  • 1. Preparing the Surfaces
    Surface Description: Hardwood and softwood decking including Treated Pine, Merbau, Spotted Gum and Jarrah.
    Preparation and application advice:
    Step 1: Ensure the timber to be treated is clean, dry and free from any dirt or loose debris. New Timber: New tannin-rich timbers should be allowed to season first or rough sanded and treated with Sikkens Cetol BL Tannin & Oil Remover to encourage oils and tannins to be drawn to the surface. Older Timber: Sand back to bare all flaking, peeling, and weathered coating. If the existing stain finish is in good condition or the timber has uniformly weathered (turned grey) with no visible finish, then sanding is not essential; move to the next step.
    Step 2: Cean the timber with Sikkens Cetol BL Deck & Wood Cleaner. Rinse and allow to dry thoroughly. For previously stained timber with an intact finish, for best results, light sanding is recommended. Remove sanding dust.
    Step 3: Apply Sikkens Cetol Deck Ultra
    Stir the can well before and frequently during use. Brush on evenly
  • 2. Cleaning
    Clean brushes and equipment immediately after use with mineral turpentine / white spirit.
  • 3. Storing
    Store in accordance with local regulations. Store in a segregated and approved area. Store in original container protected from direct sunlight in a dry, cool and well ventilated area, away from incompatible materials (see Section 10 of the MSDS file) and food and drink. Store locked up. Eliminate all ignition sources. Separate from oxidizing materials. Keep container tightly closed and sealed until ready for use. Containers that have been opened must be carefully resealed and kept upright to prevent leakage. Do not store in unlabeled containers.
