GENSTONE INSTALLATION GUIDE (cont.)

Applying Over Cement

This method of application would be used for CMU, brick, or any other cement product. Using PL polyurethane premium construction adhesive (widely available) on the back of the panels in approximately 3/8" vertical beads in a tight "s" pattern at 12" intervals starting at one edge. In conjunction with the adhesive you will need to use a cement screw such as a Tapcon. These screws will hold the panel in place while the adhesive sets as well as increase the durability of the install. One screw in each corner of a panel is adequate. Screws should be of sufficient length to penetrate the panel and bite enough into your substrate to hold tight. Screw heads should be counter sunk 1/8" and then covered with GenStone color match grout.

Applying Over Wood

This method of application would be used over plywood, OSB, or any other wood siding product. If applying over a siding it must be a relatively flat panel. Many lap sidings may have too much height difference at the lap joint. After applying a moisture barrier (per manufactures' instructions) you can use an exterior grade screw to attach the panel. Screws should be placed about every 8" on the positive edges of each panel. Take care not to place the screw too close to an edge of the material. This should be about ½" from a single edge and 1 ½" from a corner. In addition you will need to place 3 screws on the bottom part of the panel. When placing these screws locate them in the grout lines a few inches up from the bottom edge. Also one screw should be placed in the horizontal grout line in the middle of the panel about 6" from the left edge. These screws should be countersunk 1/8" and can then be hidden with the application of the grout.

Applying Over Drywall (interior)

When using GenStone on an interior drywall application proceed with the adhesive as in the above described procedure for application over cement. Screws must be used in addition or in place of the adhesive. If you choose to use the adhesive and screw method the screws must be long enough to penetrate the panel and the drywall and bite into the stud behind. With the use of adhesive the number of screws is limited but must line up with the studs. After applying the adhesive set and hold the panel in place with a minimum of four screws, one in the area of each corner on the shiplap edge or in the grout line as necessary for alignment with studs.

Applying Over Exterior Gypsum Board

Follow the above application for interior drywall to apply to an exterior gypsum board with the use of adhesive and screws. Additional screws are needed as well where the panel overlaps a stud. It is possible depending on the stud layout of the wall that you may only cross over two studs but if available shoot screws in each stud that the panel overlaps. At each stud a screw should be placed in the positive ship lap and at least one in the grout joint on that same stud.

Applying to a Steel Building

To apply to a steel building a backer board must be used. This provides a buffer between the building and the GenStone. This isnecessary because of the properties of a steel building. This substrate needs to be plywood or OSB of at least ½" thick. This board needs to be attached securely to the building using a construction adhesive and screws. Once the board is attached you can follow the same above procedure for applying to wood.

Repairing

Minor damage to GenStone products can be repaired by painting over the damaged area with Sherwin Williams Super Paint. Caulking or an exterior grade filler can be used on larger areas needing repair. If the area is larger or more severely damaged a section can be removed and replaced by another section. Cutting a section off the wall can be done with a sharp blade or a rotary saw. Scrape the area clean and use the old piece as a template to cut out the new piece. Screw and or glue the replacement section in and paint and caulk as necessary making sure that all areas are covered.

Maintenance and Cleaning

GenStone panels require very little maintenance and should be cleaned using water or warm water, or warm water and a mild soap. Water pressure from a garden hose and the use of a soft bristle brush will be sufficient. Do not use a pressure washer, particulate or sand blasting device, or harsh chemicals (bleach, acids, and detergents.) Removing all that is possible and then using touchup painting can take the place of excessive abrasion methods to rejuvenate the look.

INSTALLING STUCCO PANELS . There will need to be a screw placed in the lower left corner of the panel but there is no grout line to hide it in. The screw will need to be placed in the surface (field) of the panel and then the screw head covered one of two ways. The first being simply with our color matched grout. Try this method on the first panel to determine weather the appearance is adequate. The other option is to use a piece of scrap material and a plug cutting bit on a drill. Cut the needed quantity of plugs out of the scrap, and then trim the top (end with surface material) 1/8" of the plug off. Take this screw head cover and secure it in the countersink screw head hole using an adhesive, preferably our color matched grout.
