The professional procedure for permanently adhering rubber flooring (roll or tile) to a prepared concrete substrate. Steps: (1) verify concrete is cured (28+ days), dry (<4% moisture per calcium chloride test ASTM F1869), level (max 3 mm deviation per 3 m straightedge), and clean; (2) grind or shot-blast concrete to open pores and create mechanical bond profile; (3) apply primer if specified by adhesive manufacturer; (4) spread recommended adhesive with V-notch trowel (2-3 mm bead) per manufacturer pattern; (5) allow adhesive to tack (open time varies: 5-30 min); (6) lay rubber flooring into adhesive, working from center outward; (7) roll with 68 kg (150 lb) three-section roller to ensure full adhesive transfer and eliminate air pockets; (8) seal seams with heat welding rod (for homogeneous rubber) or seam sealer. Acclimate flooring in room (>18°C) for 24-48 hours before installation. Adhesive types: water-based acrylic (standard), polyurethane (heavy traffic), and epoxy (maximum bond, wet areas). Full cure: 24-72 hours before traffic. Per manufacturer installation guides (Nora, Mondo, Gerflor, Regupol).
