The right adhesive for turf on concrete
Use a professional, exterior-rated polyurethane turf adhesive formulated for synthetic grass. Single-component moisture-cured polyurethane works for most installs. Two-part polyurethane is a smart upgrade for colder temps, heavy-use areas, or when you need a faster, more predictable cure.
- Exterior rated, waterproof after cure
- Polyurethane chemistry designed for synthetic turf
- Compatible with concrete and turf backing
- UV and freeze thaw resistant
- Low odor and low VOC options available
- Working time and cure schedule that fits your climate and crew pace
Application pattern that prevents water problems
On concrete, bond the perimeter and seams. Do not full spread the field. Strategic bonding controls movement and preserves drainage.
Perimeter bonding
- Run a continuous bead 1/4 to 3/8 inch around the perimeter.
- Leave 2 to 3 inch drainage breaks every 3 to 4 feet along the low side so water can escape.
- Press the turf into the adhesive and set with weight until initial grab.
Seams
- Use seaming tape with polyurethane turf adhesive.
- Apply a uniform layer with a 1/8 inch V notch trowel or thick beads then trowel smooth.
- Align fibers, close the seam without overlap, and roll or weight until set.
Coverage basics
- Cartridge beads: a 29 oz tube typically yields about 15 to 35 linear feet depending on bead size.
- Trowel spread: coverage varies by notch size and product. Check the data sheet and plan extra for seams and perimeter turns.
Surface prep that makes the bond last
- Confirm the slab is fully cured, clean, and dry. No standing water.
- Remove dust, paint, curing compounds, grease, and loose materials.
- Repair cracks or spalls and grind high spots that could telegraph.
- If the surface is chalky or very porous, prime per adhesive manufacturer guidance.
- Dry fit and acclimate the turf. Allow it to relax flat before gluing.
Weather, open time, and cure
- Ideal substrate and ambient temperature is commonly 50 to 90 F unless the adhesive allows otherwise.
- Respect open time. Lay the turf within the adhesive's specified window for proper transfer.
- Roll with a 50 to 75 lb roller or use sandbags to ensure contact.
- Protect from traffic and water until cured. Light foot traffic often after 24 hours, full cure in 24 to 72 hours depending on product and conditions.
When to choose two-part polyurethane
- Cool or variable temperatures where cure speed must be controlled.
- High traffic, heavy-use zones like gyms, rooftops, or commercial patios.
- Tighter schedules requiring predictable set and cure times.
Common mistakes to avoid
- Using indoor carpet glue or general construction adhesives not rated for turf.
- Full-spreading the entire field, which can trap water.
- Gluing over dust, sealer, moisture, or damp concrete.
- Ignoring drainage breaks along the low side.
- Stretching turf while adhesive is wet, which can cause seam peaking.
