How to Install Tactile Studs, Strips and Tiles

1. Choose the fixing method

2. Layout rules

• Warning fields: 600 mm deep in the direction of travel (610 mm ADA), full width of the hazard, starting about 300 mm before a stair nosing or platform edge.
• Stud grid: 50 mm centres, square, aligned with the hazard edge. 36 studs per 300 × 300 mm.
• Guiding paths: bars parallel to travel at 75 mm centres, 4 bars per 300 mm width; at least 30 mm from walls, 600 mm from obstacles where possible.
• Decision points: a square warning field where a path turns, branches or ends.
• Confirm all values against the governing standard.

3. Tools

MetalX fibreboard template (supplied), chalk line, tape measure, straight edge, marker; for stems: hammer drill, Ø8 mm masonry bit, hole-cleaning brush and blower, epoxy or polyester anchoring adhesive with mixing nozzle; for adhesive: isopropyl alcohol, lint-free cloths, rubber mallet; for tiles: Ø6 mm bit, wall plugs, construction adhesive, screwdriver; safety glasses, dust extraction, knee pads.

4. Method A: stem in epoxy (drill-and-fix)

1. Set out the field or path with chalk lines.
2. Place the template and mark every hole with a marker.
3. Drill Ø8 mm (check the stem diameter on your drawing) to the stem length plus 5 mm. For bars, drill all three holes.
4. Blow and brush each hole clean; dust prevents adhesion.
5. Inject epoxy to about two-thirds of the hole depth.
6. Press the stud or bar home, twisting slightly to spread the adhesive. Wipe excess immediately.
7. Check alignment with a straight edge before the adhesive gels.
8. Allow to cure per the adhesive data sheet (typically 2–24 hours depending on temperature) before opening to traffic.

Poly-sleeve studs: push the sleeve into the hole first; it grips while the adhesive cures. Hollow-back studs: fill the recess with adhesive and press onto a bed of adhesive on the floor.

5. Method B: 3M self-adhesive (peel-and-stick)

1. Confirm the floor is smooth, dense, sound and between 10 °C and 40 °C. Seal porous stone; strip wax.
2. Set out with chalk lines and place the template.
3. Wipe each position with isopropyl alcohol; let it flash off. Do not touch the cleaned floor.
4. Peel the liner, drop the stud or bar into the template, press firmly for five seconds. Tap with a rubber mallet.
5. Move the template and repeat. Reposition within one minute if needed.
6. Open to foot traffic immediately. No wet cleaning for 24 hours; full bond in 72 hours.

6. Method C: screw-fix (carpet and timber)

1. Mark positions with the template.
2. Pierce the carpet at each mark and drill a pilot hole into the subfloor.
3. Place the flanged stud or bar and drive the countersunk screw until the flange clamps the carpet without dimpling it.

7. Method D: integrated tiles

1. Dry-lay the tiles to set out the field (two rows for 600 mm depth) and mark the corner holes.
2. Drill Ø6 mm, insert plugs.
3. Apply a bead of construction adhesive around the underside of the tile.
4. Position the tile, drive four countersunk screws.
5. Butt adjoining tiles tightly so the 50 mm grid continues across joints. Cut tiles with a grinder (metal) or saw (PU), keeping at least one full row of studs.

8. Inspection and handover

• Every stud and bar firm, level and aligned.
• Grid and spacing checked with the template; field depth and setback measured.
• Contrast checked visually and, where required, with a luminance meter.
• Photographs and the material certificates filed for the access audit.

9. Maintenance

Normal floor cleaning is sufficient for all MetalX products. Avoid abrasive pads on PVD finishes and acidic cleaners on brass. Replace any damaged stud or bar promptly: cut and drill out a stem fixing, or warm and lift an adhesive fixing, then fit a new piece.
