Read installation instructions carefully before proceeding.
Caution: Wear safety glasses with side shields and NIOSH approved dust/particle mask when cutting, drilling, or in any matter machining RezCast® products.
Products Storage: Product should be stored at ambient or room temperature, lain in flat position, until installation.
RezCast® products are installed using adhesive and mechanical fasteners (screws, nuts & bolts, etc.) to assure a proper attachment. Corrosion resistant fasteners such as stainless steel or brass screws are preferred. We recommend using high quality adhesives such as E-6000, Sonneborne NPI, Slika 31 Epoxy Gel, Silkaflex 221 or 252 depending on the substrate and conditions.
RezCast® products must be installed over a clean, dry surface. The backside of the stair tread covers or mats may be lightly abraited with emery or a Scotch Brite pad to remove the sheen and enhance bonding. Fastening accessories including drill bits, countersinks, and adhesives are available from RezTech Industrial Services.
- Electric Drill*
- Crescent wrench
- Tape measure rubber
- Plastic mallet
- Caulking gun
- Notch trowel
*Concrete is drilled best with a hammer drill and masonry bit.
Drill Bits & Fasteners
- Masonry bit (drilling RezCast® products requires a masonry bit)
- Concrete screws
- Tap Concrete screws (drop in sleeve type with stainless steel machine screw fastners, recommended if tread removal becomes necessary)
- Mush head spikes
- TiN Titanium coated cobalt bits
- Carbide tipped countersink bit
- Stainless steel nuts and bolts
- Pop Rivets
Carbon or Black Steel
- High speed drill bits
- Stainless steel nuts and bolts
- TEK self-tapping screws
- Pop rivets
- *Pilot hold drilled with high speed bits may facilitate fastening if the aluminum is thicker than 1/8″
- High speed drill bit
- Wood screws
- Saddle Clip Fasteners
- Pre-fit the RezCast® product to the application surface. Drill fastening ports in the RezCast® component and set the tread into place.
Note: Fastener holes should be placed no closer than 1″ from the outside edges of the component and no more than 24″ apart. A countersink bit is used for flathead screws.
- Using the pre-drilled holes in the component as a template, mark drilling points on the substrate surface. Remove the tread cover.
- Drill holes at marked locations to the proper fastener depth, allowing for the thickness of the RezCast® component.
Note: Wood or steel fasteners will require an undersized hole in the substrate to set the screw securely. For example, a 1/4″ diameter wood screw should require no more than a 1/8″ pilot hole to set the screw.
- With a caulking gun, apply a minimum 1/4″ bead of adhesive to the underside of the RezCast® product approximately 1″ from outside edge of step cover or mat. For concrete or diamond plate steel, apply a 3/8″ bead of adhesive.
- Replace the component and, using a screwdriver and the appropriate fasteners, secure the component to the substrate. Do not overtighten.
- Some RezCast® products can be installed with either of the recommended adhesives above other clean, dry surfaces with temperatures at or above 72°F with 24 hours drying time before opening to traffic.
*Note: These installation guidelines and graphics are not to be viewed as a standard installation practice, but only as a general reference guide. It is the responsibility of the installer to consider the installation of each RezCast® product component separately and to make reasonable decisions to achieve the most satisfactory product installation. RezTech Industrial Services assumes no responsibility or liability for substandard installation practices.
