AZEK Porch
AZEK does not recommend the use of rubber or vinyl products (welcome mats, planters, etc.) on porch boards. A reaction can occur that causes discoloration of the board under the rubber/vinyl product. This is a common caution for vinyl decking products. Do NOT nail AZEK Porch boards. Although AZEK Porch is cooler to the touch than many other porch boards in similar colors, all porch products will get hot in the sun. Additionally, the darker the porch color, the hotter it will feel.

Walking Surface and Grain Pattern
AZEK Porch boards must be installed grain side up.

Static Electricity
Static build-up is a natural occurring phenomenon that can occur with many plastic products including PVC Porch. It could occur with AZEK Porch under the right environmental conditions.

For best results, donít cantilever over 1/2Ē.

AZEK Porch/Rim Joist Covers/Riser should not be routed.

Color and Painting
Color variation is purely aesthetic and does not or will not affect the performance of the product. Depending on environmental conditions, AZEK Porch colors may appear to lighten over time as part of the natural weathering process. Painting is not recommended for AZEK Porch.

AZEK Porch is NOT intended for use as columns, support posts, beams, joist stringers, guard railing or other primary load-bearing members. AZEK must be supported by a code-compliant substructure. While AZEK Porch products are great for replanking (removing old porch surface boards and installing AZEK on a code-compliant substructure), AZEK Porch boards CANNOT be installed on top of an existing porch. AZEK Porch is not intended to be waterproof and should not be used in any waterproof application. Caulks, adhesives or other similar products should not be used in the tongue and groove areas of AZEK Porch.

Failure to install AZEK Porch products in accordance with applicable building codes and this Installation Guide may lead to personal injury, affect porch/deck system performance and void the product warranty.

Azek Porch

Be aware of excessive heat on the surface of AZEK products from external sources, such as but not limited to, fire or reflection of sunlight from energy-efficient window products. Low-emissivity (Low-E) glass can potentially harm AZEK products. Low-E glass is designed to prevent passive heat gain within a structure and can cause unusual heat build-up on exterior surfaces. This extreme elevation of surface temperatures, which exceeds that of normal exposure, can possibly cause AZEK products to melt, sag, warp, discolor, increase expansion/contraction, and accelerate weathering.

Current or potential AZEK customers that have concerns about possible damage by Low-E glass should contact the manufacturer of the product which contains Low-E glass for a solution to reduce or eliminate the effects of reflected sunlight.

It is important during construction, the deckís surface stay clear from excessive build-up of dirt, sand, and dust from tile, concrete, landscape blocks, or any other masonry products. If these materials are not removed immediately, the deck surface will become difficult to clean and can potentially damage the deckís surface finish.

Do not use AZEK Porch as a work surface.

If a build-up does occur please refer to the Care and Cleaning section in AZEKís installation guide or website,
