Ducan Vinyl-Dek is a blend of vinyl and acrylic resins that offer exceptional adhesion and water repellent features.

It is the perfect maintenance coating for previously coated surfaces such as acrylic latex based coatings, enamels, oil stains and latex stains.

Before re-coating your deck and for best appearance and longevity, thoroughly inspect your deck.  Examine the flashings and drains.  Check for excessive railing post movement, delaminated plywood, nails popping and lifting, loose or blistered areas and make sure the expansion joints between the plywood sheets are properly filled.  These areas must be corrected prior to re-coating.


  1. The surface should be clean, dry and free from oil and grease as this will interfere with a tight bond.

  2. Use Ducan's "THE DUKE – powerful concentrated cleaner and degreaser" to clean and remove algae, stains and other material that will interfere with a good adhesion. Rinse well and let dry thoroughly.

  3. Thoroughly stir the Vinyl-Dek until no sediment remains in the bottom of the container.

  4. With a brush, paint a full coat of Vinyl-Dek around railing posts and all edges of the deck.

  5. Prepare the roller and attach the extension.

  6. Fully dip the roller into the Vinyl-Dek while making a stirring motion. (Do this with each pass).

  7. Apply the wet roller without heavy pressure to the deck and roll out the material 24” to 30” per roller full.

  8. Make sure a puddle of Vinyl-Dek stays ahead of the roller to evenly distribute the material.

  9. Refill the roller on every pass. Make 3 or 4 passes next to each other. The area covered should be approximately  2’ x 3’. Let the first application dry 2 to 4 hours.

  10. Important: Thoroughly intermix the contents of the containers to ensure colour uniformity. This is mandatory if different batch numbers are being used.

  11. If a second application is necessary, start in a different corner and work at right angles to the first application. Repeat steps 4 thru 10.

Allow only light traffic for the first 14 days.


Untreated surfaces: 2 applications are required.
Concrete surfaces should be cured for a minimum of 28 days, be sound, non-powdery and free from hydrostatic pressures. Curing compounds or polished surfaces should be acid etched with a 25% solution of muriatic acid and water and then rinsed with copious amounts of clean water.  Let surface air dry for a minimum of 3 days. To detect hydrostatic pressure, (excessive sub-surface moisture), tape a piece of plastic to the surface for 24 hours. If there is any moisture beneath the plastic when it is removed, there is too much hydrostatic pressure for Vinyl-Dek application.


The surface should be sanded (50 Grit) and cleaned with Ducan's "THE DUKE – powerful concentrated cleaner and degreaser" to remove sanding dust, wax and silicone agents from the surface, as this will impede good adhesion. (Two applications of Vinyl-Dek are required.)


Metal surfaces should be wiped clean with household vinegar to remove oxidation. Areas of rust should be ground out to bare metal and a suitable metal primer sealer applied before Vinyl-Dek can be applied. (2 applications of Vinyl-Dek are required.)


Apply Ducan Vinyl-Dek at the rate of 2.5 U.S. Gal per 180 sq. ft., one coat (2 applications are required for previously uncoated surfaces).


Apply when temperature is between 10°C to 30°C (50°F to 89.6°F).


Do not apply if:
  • Rain is forecast in the next 12 hours.
  • Temperature is expected to fall below 10°C (50°F) within 24 hours.
  • The surface is warm to the touch under direct sunlight.
  • It’s late in the day and the dew point will be reached in 2 to 4 hours

All surface types must be dry, clean and free from dirt, oil and grease with not more than 12% moisture.


Nail Popping
Remove excess rust from nail, drive a galvanized nail next to original nail, use Ducan Rubber Fill-It to fill indentation until flush.

Nail Lifting
Re-drive nail using set punch, use Rubber Fill-It to fill indentation until flush.

Loose or blistered areas
Remove to bare wood and repair damaged area with Rubber Fill-It until flush with surrounding surface.  Polyester tape will be required if new plywood is inserted into the damaged area. The entire surface of any new plywood must be skim coated with Rubber Fill-It before applying Vinyl-Dek. Do not use Vinyl-Dek directly on new plywood.

Cracking at joints
Usually caused by plywood joints placed too close together (less than 1/8”), excessive deck movement or insufficient filler. Re-groove the joint using a razor knife for small distances (up to 12”) or a circular saw set at 1/8” depth and run along the joint, use Rubber Fill-It and polyester tape to refill joint until flush. Note: Be sure joint is properly supported from underneath.

De-laminated Plywood
Usually caused by joints too close together and/or air pocket in plywood. Use razor knife to dig out affected area. Use Rubber Fill-It and polyester tape to refill joint until flush.

Soft or Spongy Plywood
Replace affected area to supporting joist and crossmember. Shims might be necessary to increase height of replacement sheet. Fill joints with Rubber Fill-It until flush with previous coating. The entire surface of any new plywood must be skim coated with Rubber Fill-It before applying Vinyl-Dek. Do not use Vinyl-Dek directly on new plywood. Do not install on pressure treated lumber. K-3 board, particle board and OSB are not recognized as suitable exterior sub-floor materials.
