Installation over wood or steel etc. 
Step 1: Prepare – 
Remove any existing coverings from stairs (if applicable). Remove nails, staples and stair nosing 
Lightly wire brush the existing steps or sand if required. Surface should be smooth and void of any large imperfections 
(see warranty notes below) 
Lightly sand the back of the ComposiGrip step cover 
Wipe down both surfaces with acetone, paint thinner or similar cleaner. 
Ensure all surfaces are clean, dry and free of dust before proceeding 
Step 2: Install – Before cutting step cover, ensure pattern match 
Measure the length and width of the existing stair tread. Transfer the measurement to the ComposiGrip step cover and cut 
accordingly. A circular saw can be used for the majority of the cuts. We recommend using diamond grit tile-cutting blades for 
cleanest cut. 
For indoor applications 
Apply the construction adhesive to the back of the step cover following construction adhesive recommendations 
Using a 3/16 x 3/16” adhesive spreader apply adhesive evenly across the entire backside of cover. 
Place cover in desired location firmly  pushing down on to existing step . Once properly located clamp or place weight evenly 
distributed on the cover . Follow adhesive manufactures recommendation for clamping/curing time. 
Outdoor applications 
We recommend adding stainless or coated fasteners; minimum 1.25” long. 
Drill clearance holes for the stainless steel or coated fasteners.  
Fasten step cover to the existing stair tread. Ensure the step cover is level and squared. Use a minimum of 5 fasteners per 
step cover and fasten in an ‘X’ format (2 at each end and 1 in the middle). 
Step 3: Finish - Optional Fill the holes with matching color silicone 
Installation on landing 
Step 1: Prepare – 
Remove any existing landing coverings (if applicable). Remove nails, staples and stair nosing 
Lightly wire brush or sand the existing landing 
Lightly sand the back of the ComposiGrip flat sheet 
Wipe down both surfaces with acetone, paint thinner or similar cleaner 
Ensure all surfaces are clean, dry and free of dust before proceeding 
Step 2: Install - Before cutting flat sheet, ensure pattern match 
We recommend adding stainless or coated fasteners; minimum 1.25” long. Measure the length and width of the existing landing. 
Transfer the measurement to the ComposiGrip flat sheet & cut  accordingly. A circular saw can be used for the majority of the 
cuts. We recommend using diamond grit tile-cutting blades for cleanest cut.. Drill clearance holes for the stainless steel or coated 
fasteners. Apply the construction adhesive to the back of the flat sheet following construction adhesive recommendations. Using a 
3/16 x 3/16” adhesive spreader apply adhesive evenly across the entire backside of sheet. Fasten sheet  to the existing landing 
with stainless steel fastener. Ensure the sheet is level and squared. Use a minimum of 5 fasteners per sheet and fasten in an ‘X’ 
format (2 at each end and 1 in the middle). 
Step 3:  Finish – Optional  Fill the holes with matching color silicone 
Improper Installation will Void the Warranty:
 ComposiGrip Step Covers are NOT structural parts and are NOT designed to 
support full load of step. The load-bearing capacity of each Step Cover is dependent upon the load-bearing capacity of the step it 
is covering. Step Cover is not designed to bridge large voids or gaps. Deteriorated steps should be filled or levelled prior to 
installation of Step Covers. All voids larger than 2-inch (5 cm) diameter should be filled. Installations on highpoint load applications 
(such as ‘Bear-Claw’ style gratings) should be made using ComposiGrip high strength Industrial Step Covers.
