VersaDek Ultra is a slip resistant waterproof covering that is resistant to chemicals, mildew, and ultra-violet light. It can be used both indoors and out over concrete, plywood or old decking. VersaDek is made from PVC with polyester embossed onto it for added strength and flexibility. Rolls are 6' x 120'.

1. SURFACE PREPARATION

PLYWOOD should be clean and dry, at least 3/8" AC-X installed according to the manufactures directions. Fill joints, nailheads, etc with an exterior patching compound following the manufacturer's recommendations.

IMPORTANT: Do not apply VersaDek over plywood that has patches unless they are wood or urethane. Other materials can cause staining.If you must use plywood with these patches, break out the patch and replace it with proper filler.

CONCRETE should have a relatively smooth finish. Fill any imperfections with exterior patching compound, following the manufacturer's recommendations.

METAL OR PREVIOUSLY COATED SURFACES require special procedures. Call us for assistance before proceeding with these installation.

2. DETAILS are shown in this section. If yours isn't call (800) 497-3325.

VersaDek should run up the wall 3" & under the siding. If VersaDek can't be installed under the siding, invert a drip edge flashing against the wall, turn the VersaDek up over the flashing and cut off flush with the wall & caulk. This method is good on brick or stucco. On rough stucco grind off the stucco where it interferes with the flashing. If there are gaps where the deck meets the wall, use a cant strip [2x2 cut at 45 ). Otherwise, a bead of caulk will make the transition. See illustrations below

WOOD OUTSIDE EDGES need a 1-1/2x1-1/2"x1/2" drip edge flashing installed using ring shank nails spaced every 3" See illustration On smooth concrete or wood deck edges you may install VersaDek without using drip edge metal. Use a quality caulk to glue & seal down the last 1"of VersaDek.
POSTS, should have a 3"collar of VersaDek installed on them before installing the flat work. Seal the collar and the joints between the collar and the VersaDek by heat welding or use a good quality caulk. Use caulk to seal the collar to the post.
OUTSIDE WALL CORNERS A piece of VersaDek is glued on the wall and down onto the deck prior to the installation of the flat work. Seal with caulk.

INSIDE CORNERS 90 degree corners, fold the VersaDek at the corner & cut so they join in the center. Then seal with a good quality caulk.

3. INSTALLATION Plan to leave 3" of material to run up the wall & a 3/4" overlap for seams. Mark the C/L of each seam . If using VersaSeam system mark 6" on each side as well. These extra lines are to help keep adhesive away from the seam until after it is cut. Plan to minimize seams & waste. Avoid seams at stairs or near doors. Run seams parallel to the wall. Install on stairs by cutting pieces that just cover a tread and riser. [This way the treads are easily replaced.] Before spreading adhesive unroll VersaDek out onto the surface, make rough cuts & half roll it back up. This helps hold the VersaDek in proper alignment.

VERSADEK ADHESIVE is applied with a 1/8 V notch trowel, using a linear pattern at temperatures between 45 & 90 F. Then unroll VersaDek into it while wet. Roll out in a fan pattern using a lightweight roller or carpet tube . Keep traffic light & the temperature above 32F at least 8 hours after installation. Once the surface is done, glue all edges. Follow instructions on the can. Knife trim VersaDek at flashing edge. VERSADEK ADHESIVE must be used or warranty is void.

4. HEAT WELDED seams are done in two steps. First; after you have installed the sheets of VersaDek, put a 1/4" bead of caulk on top of the bottom sheet close to the edge. Be careful too much caulk will contaminate the seam area. Hold the roller flat, & lightly roll the seam lengthwise on the overlap.

VersaDek customers receive a heat gun kit, which includes a no-charge heat gun rental plus a free instructional video.

Second: Set up the heat gun by installing the tip & reducer. Make sure the tip is oriented horizontally and pointing away from you. With the dial set at #6.

Test for the correct temperature setting by holding the tip about 1/2" away from a scrap piece. It should turn shiny in 8 to 10 seconds. Adjust the dial one notch at a time until the proper result is achieved.

Basically you heat just the top edge until when you roll it the two pieces fuse together [hold the roller at 45 degrees so that just the edge of it contacts the edge of the top piece] . Keep moving the heat gun forward, following with the roller until the seam is completed. Finally inspect the seams for proper bonding, look for loose areas and reseal. What you want is for the VersaDek to stick together without becoming shiny.

WE HIGHLY RECOMMEND YOU PRACTICE ON SOME SCRAPE PIECES BEFORE YOU BEGIN WORK ON THE ACTUAL SEAM.

5. CAULKING The installer must examine the deck carefully looking for areas that water could seep into under the worst weather conditions (wind driven rain, melting snow, etc. ) and take the necessary steps to prevent it. Caulk all exposed edges, posts, and trim strips as shown. We recommend the use of a good quality polyurethane caulking. Which is available from Home Depot [PL brand] or C.R.Laurence[#M66] (800)421-6144. Due to the plasticized nature of the VersaDek, a silicone or cheap caulk or sealant will not bond to its surface.

6. DRAINS Prior to installation inspect the surface for proper drainage. If necessary install a good quality drain, following the manufacturer's instructions or call us at (800) 497-3325.Note: Standing water will not harm VersaDek, but you may find it annoying to have puddles on their deck.

7. VENTILATION is an extremely important aspect of single-ply decking. Adequate ventilation of the air space beneath the substrate is necessary to avoid condensation and the resultant problems. The responsibility for adequate ventilation lies with the building designer or engineer. If the applicator suspects inadequate ventilation, they should point out the potential problem area to the owner or contractor so that they can remedy the situation.
