***Please note, it is now REQUIRED on all of our elevated decking applications to either apply a sister joist to each main joist or use our 2x4 sleeper system method when installing DekTek Tile.*** See Installation - "Elevated Decks" for more information, or please call 218-380-9330 with questions.

 

Framing

1. Lateral bracing, same width as existing joists, is required at a maximum of 4' on center.

 

 

Step 1

2. Add a sister joist to each existing joist and be sure to leave a ½” to ¾” drain plate (spacer) in between the sister joist and the main joist. If joists are capable of handling 11 1/2 pounds per square foot dead load then a 2"x4" sister joist is sufficient. If additional joist capacity is needed then you might have to add a  2"x6", 2"x8", or 2"x10", etc. in lieu of a 2"x4". Your local lumber yard can usually calculate this for you. Make sure you also calculate the load for the beams that carry the joists.

 

Step 2

 3. Add decking border where needed. Add additional framing to facilitate borders, if needed.

Setting

DekTek Tile CAD Drawing

Tile setting skills are highly recommended.

Setting Equipment Needed:

  • Caulk Gun
  • 10" Wet Diamond Saw
  • Chalk Line
  • Tape Measure

First layout the tile grid plan for overall tile positioning. If you are using wood or composite decking for trim or borders then they have to be installed first and then DekTek Tile filled in between them. The tile must have a minimum of 3/8 inch bearing on joist. Tile is then set using a high quality exterior polyurethane adhesive directly to wood joists. We recommend Liquid Nails Marble & Granite and Solid Surface Materials Adhesive and Liquid Nails Polyurethane Adhesive. It has a high temperature range of -20º F to 300º F and has a longer open time for adjusting tiles after they are set. Tiles should be set with an approximately 1/8 inch gap between tiles which allows water to drain.

 

Step 4

 

Sealing

DekTek Tiles should be sealed with a high quality concrete sealer on top and all sides before installing. Be careful not to apply sealer to bottom of tile. When sealer is applied to bottom of tile it can break the bond of the adhesive.

Sealer for DekTek Tiles

We recommend using a good solvent-based sealer that is for acid stained or stamped concrete. We do not recommend any specific brand. There are many brands of concrete sealers on the market that are high quality. Please feel free to consult your local concrete expert. Cemstone is our regional brand, located in the upper mid-west, which has a line of concrete sealers that has worked well for some of our clients.

***Water-based sealers are not recommended because they tend to peel. We also do not recommend using penetrating sealers as our tiles are too dense and it does not protect the tile surface. ***

Here is more information on Cemstone’s concrete sealers.
