60 mil Vinyl Installation Instructions

READ ALL DIRECTIONS BEFORE BEGINNING

IMPORTANT: In inclement conditions, the plywood must be kept dry. Make a barrier by suspending a tarp at lease 24" from the deck surface. Hint: Use the roof fascia.

IMPORTANT: Do not apply
adhesive when the deck is hot to the touch from direct sunlight. Ducan does not warranty Dek-Master® on stairs.

It is not necessary to install Ducan Dek-Master® vinyl on pressure treated lumber. If it is a city requirement there should be no more than 12% moisture content in the plywood.

Do not install to K-3 board, particle board and OSB as they are not recognized as a suitable exterior sub-floor material.

Installation
  1. Carefully sweep off the deck surface and make sure it is free of all debris.
2.

It is optional to install galvanized metal cantstrip at the house to deck interface or if running vinyl sheet up the wall, install 2" x 4" galvanized 90° metal flashing at the house to deck interface. This will act as an attachment transition between the deck surface and the house.

NOTE: It is always preferable to run the vinyl up the cant strip or flashing and under the siding and tar paper.

 

3. Install galvanized metal flashing around perimeter to protect the edges of the plywood from moisture and to act as an attachment area for the vinyl. Install 1/4" away from the edge of the plywood using 1 1/4" galvanized ring nails, starting from the center and working your way out.
4. Once cant strip and non-return drip flashing have been nailed to the deck, fill all joints and surface imperfections with Dek-Master® Dek-Patch joint filler and patching compound. Follow mixing instructions on the label. Fill all joints, screw indentations, surface imperfections and transition of cant strip and flashing to the deck surface. It is important when leveling out the flashing or cant strip edge that the Dek-Patch doesn't build up on the top surface. To avoid grinding or sanding, just before the Dek-Patch hardens scrape off excess and ridges with a trowel.

IMPORTANT:
Do not allow the Dek-Patch to freeze for 24 hours. DO NOT ALLOW DEK-PATCH TO GET WET.
 

Your surface is now prepared and you are ready to install your waterproof Dek-Master® sheet vinyl. Do a review of the video, brochure and web site before proceeding.

Tip: To be sure the vinyl is square on the deck, draw a chalk line in pencil so that when you unroll the vinyl you can be sure that the sheets are square on the deck surface.

5. The pattern of the vinyl is directional. Lay each sheet in the same direction. Lay out Dek-Master® vinyl to ensure the fewest possible seams. Start from the furthest point from the building and allow 1" to 2" of vinyl to go over the flashing and 8" for up the wall of the building. Adjust the vinyl sheet to ensure it is parallel to the wall and/or deck edge. Tack within 1" of upper edge to hold in place temporarily. The seam area will be Hot Air Welded so putting a tack or staple in this area is safe.

IMPORTANT: Colour variances from roll to roll are common. Ducan can not be responsible for any material applied from two separate rolls (lot numbers). Lot numbers can be found on a sticker inside the rolls of vinyl.
6.

It is not necessary to adhere the vinyl to the flashing or cantstrip until the end of installation. Only adhere the vinyl to the top of the deck surface.

Fold vinyl sheet back half its width (as shown at left) and first apply Dek-Master® SnapTac Adhesive to the deck surface, secondly to the back side (fuzzy side) of the vinyl.

IMPORTANT: Both surfaces must have a complete thin and even coat of SnapTac Adhesive. (Pro Water Based Adhesive is a trowel on product that goes on the plywood surface only.)

7.

Let the adhesive dry until tacky. Test the tack by placing your finger to the adhesive coated back side (fuzzy side) of the vinyl. Adhesive should be stringy between your finger and back side of the vinyl

.

8. Push adhesive coated vinyl sheet down onto the deck surface by working with your hands from the middle point to the edge of the deck, then outwards to the ends. (If using Pro Water Based Adhesive you must use more pressure to push the vinyl into the glue. A block of wood can be used.)

IMPORTANT: Ducan recommends using your hands to smooth the vinyl down. If an air bubble forms in the vinyl, smooth it out with your palms. If you find you are acquiring solvent bubbles under the vinyl this could be from temperature or too much adhesive. Push the bubbles down. Most likely after a few days they will go down on their own once the solvent dissipates.

Note: Use of a roller or rolling pin can cause stretching of the vinyl with SnapTac Adhesive. DO NOT USE.

WHEN TO APPLY: Temperatures between 10°C/50°F and 35°C/95°F are best. The plywood surface must be clean and dry, with no more than 12% moisture content. Do not apply to pressure treated lumber because of the moisture content.
9. Remove tacks or staples and fold the vinyl sheet back as shown at left. Apply Dek-Master® SnapTac Adhesive to the back of the vinyl and to the deck surface.


10.

Again, push adhesive coated vinyl sheet down onto the deck surface by working from the middle point to the edge of the deck, then outwards to the ends.

 

11. Subsequent vinyl sheets must be overlapped 1" to the adhered vinyl sheets. To prepare subsequent sheets, place a piece of 1" masking tape to the underside edge (fuzzy side) where the overlap will be. It is necessary to follow this step to ensure the soon to be applied adhesive does not interfere with the Hot Air Welding process. This tape will be removed prior to completion of the Hot Air Welding.
12.

Install 1" masking tape on the edge of the first panel (patterned side). This will protect the vinyl seam area against any adhesive that may end up on it. It will also act as a guide as you slide the corresponding sheet over to achieve the necessary 1" overlap.

This tape will be removed prior to completion of the Hot Air Welding.

13. For subsequent vinyl pieces, follow the same procedure as you did for the first panel, folding the sheet over half way, adhering and then folding back the other in the same way. If needed, use waxed paper to protect the previous panel while gluing the second one.
Finishing
A. Hot Air Welding
Lap joints must be a minimum of 1" to 1 1/2" and be fully hot air welded. Remove the temporary tacks or staples and the two strips of 1" masking tape and make sure there is no SnapTac Adhesive residue in the overlap area before you proceed. Ducan offers the hot air welder along with a DVD for those wishing to use this method. Please contact your retailer or Ducan Customer Service at 1-800-943-8226 regarding the rental of this unit.

IMPORTANT: Ducan strongly recommends repeated practice prior to working on the actual deck seams. The more practice the more professional the deck will look and the more water tight the seal.

WARNING:
Do not use excessive pressure with the seam roller as this could distort the vinyl layer.

Hot air welding seams is an option for the 45 mil and is required for the 60 mil vinyl. Ducan offers the hot air welder along with a DVD for those wishing to use this method. Please contact your retailer or Ducan Customer Service at 1-800-943-8226 regarding the rental of this unit.
B. Finishing the Edges
Now that your deck surface is completely sealed it's time to prepare for the vinyl attachment to the perimeterflashings and (optional cantstrip) and edge leading up to the wall of the building.
C.

Cantstrip Finishing

Make sure the vinyl is completely adhered to the optional cantstrip and the flashing leading up the wall by using Dek-Master® SnapTac Adhesive. With a small brush suitable for enamel paints, coat both the flashing and cantstrip with SnapTac Adhesive, wait until tacky, and adhere. Be sure to get into the crease between the deck surface and the flashing. Tightly push the vinyl against the optional cantstrip to make sure it is well adhered. Be sure to go up the wall 8" as this is a requirement for permit. Vinyl can be stapled or tacked on the upper edge to the building to keep it from moving when installing the siding.

D.

Finishing Flashings and Outside Corners
With a razor knife, trim the vinyl flush with the edge of the flashing. At the corners, cut the vinyl from the outside edge to the deck corner in line with one edge. With a small brush suitable for enamel paints apply a coat of Dek-Master® SnapTac Adhesive to the flashings and onto the back of the vinyl. Be sure to keep the adhesive off the corner areas where the hot air gun will be welding the corner flap. Tightly push the vinyl against the flashing to make sure it is well adhered.

Fold the outside corner flap around the outside corner first, then pull the top flap over the first. Hot air weld the top flap to secure to the flap beneath. Using a utility knife, cut the vinyl even with the flashing and install the U-Channel deck clips over the edge of the vinyl covered flashing.

Recommended Tip: Apply Overlap Cement every 4" to 6" inside the U-Channel canal to chemically weld it to the vinyl covered flashing. This keeps it securely fastened to the flashing.

If installing railing after your vinyl is down, be sure to use Dek-Master caulk/sealant to keep water from penetrating in the post area.

NOTE: From time to time you may run into a situation that is different from the instructions above. If you have questions, please call our technical support line at 1-800-943-8226.
