RECOMMENDATIONS FOR NEW CONSTRUCTION
All studs must be straight and true to avoid bulges or dips in the finished wall. Correct any bowed studs prior to installation if necessary. Sub-wall assembly must be weather tight before applying NextStone™. NextStone™ accessories alone may not constitute a waterproof installation. Wall sheathing should be weather-resistant, or covered with a weather-resistant barrier such as fanfold insulation, house wrap, or building paper. Independent studies indicate that the combination of a weather resistant barrier plus a house wrap results in improved weather performance. Some building code jurisdictions are currently requiring this protection. sheathing must be properly fastened to the framing according to building code requirements and/or the sheathing manufacturer’s recommendations. NextStone™ should be applied over a sheathing that provides a smooth, flat, solid, non-expansive, stable surface. Flashing and caulking should be added as needed in such areas that transition from NextStone™ to other siding products, windows, and doors to control moisture and protect the sub-wall assembly.
RECOMMENDATIONS FOR EXISTING STRUCTURES
Secure or remove any loose siding material and replace any rotten wood. Scrape off loose caulk and other build-up that may interfere with the NextStone™ installation. Remove all items such as downspouts, light fixtures, vents. etc. in the area to be covered. Install suitable sheathing, as needed, to provide a smooth, flat, and stable surface for the installation of NextStone™ panels. See above information in the New Construction section for additional instructions on sub wall protection and flashing.
RECOMMENDATIONS FOR MASONRY STRUCTURES
A smooth, flat, stable surface is required for proper installation of NextStone™. Concrete, cinder or brick walls may need filling unless they are already in a smooth and flat condition. Uneven walls may require furring strips to provide a flat surface. When applying NextStone™ directly to concrete, cinder, or brick walls, the use of concrete screws (such as Tapcon™) is recommended.
