SURFACE PREPARATION

• Surface preparation is key. The entire surface must be flat, structurally sound, dry, and stable. The

surface should be clean and free of dust, dirt, oil grease, paint, curing agents, sealers, loosely

bonded toppings, loose particles, old adhesive residues, and any other substance or condition

that may prevent or reduce adhesion.

• Acclimate material a minimum of 24 - 48 hours prior to installation in the environment where it

will be installed.

• Scrape or remove any contaminants, substance or condition that may prevent or reduce

adhesion. Some substances may require mechanical grinding for removal.

• Sand or grind down all areas as needed. All surfaces must be smooth and flat, or imperfections

may show-through.

• Install any metal flashing or trim that is required for the installation such as a metal drip edge

around the outside perimeter of a deck.

• Fill in all depressions, joints, gaps, or damaged areas as needed with a latex cement-based

patching compound and sand smooth once it has “thoroughly” dried.

• Sweep and thoroughly vacuum.

• Seal all patched areas, pitch pockets, pitch streaks, red chalk, wood knots construction adhesive,

wood filler, etc. with an appropriate primer. Follow manufacturer’s directions for proper

application and mixing.

• Suggestion: Zinsser Bin Shellac Based Primer Sealer

• Do a final inspection to ensure the surface area is suitable and ready for the application of the

Dec-Tec DIY

• IMPORTANT: Thoroughly inspect all material for visible blemishes or defects before starting the

installation. Installation of defective material will be regarded as acceptance of its condition

regardless of the defect and will void the product warranty.

INSTALLATION

LAYOUT

• Plan your layout to avoid an unbalanced installation. As a rule of thumb, material should run

lengthwise and parallel to the most dominant wall to achieve the best appearance.

• Make sure the surface area is square before laying out the material. Measure the diagonals from

all four corners. Take a tape measure and measure the distance from one corner to its diagonal,

and then measure the diagonal between the remaining two corners. If the measurements equal

one another, your surface area is square. If the measurements are different, you can make

adjustments with the first panel during the dry-fit. That's all there is to it!

• If installing on an exterior deck, it is recommended to start from the outside edge of the deck

surface and work towards the building.

DRYFIT

• Measure in 73" from outside edge when using 74” wide product or 36" from outside edge when

using 37” wide product and snap a chalk line. This will provide for a 1" overhang over the outside
