5 Best Faux Grass Adhesives (2026): Turf Glue for Seams, Concrete and Decks
As an Amazon Associate we earn from qualifying purchases.
Turf glue does two jobs: it locks seams together and it holds turf down on concrete, wood and other hard surfaces.
Turf adhesive is an outdoor glue, usually polyurethane, spread on seam tape or a hard surface to bond turf permanently. Get the glue wrong, and seams pop open after the first hot summer. Use too much, and it oozes up between the blades and leaves a stiff, matted line across the lawn. So the right product matters, and so does how you spread it.
This guide covers when you need glue, which type to choose, five good adhesives and how to apply them. We compared seller-listed specs on Amazon and Lowe's, and read installer guidance from NexGen Lawns and turf maker CCGrass.

When do you need turf adhesive?
Glue is needed wherever turf meets turf or meets a hard surface. Here's where:
- Seams on soil installs. Where two pieces of turf meet, they're glued onto seam tape underneath. NexGen Lawns calls tape and glue the most popular seaming method.
- Perimeters on hard surfaces. On concrete, decks and pavers, there's nothing to nail into. Glue holds the edges down.
- Stairs and steps. Turf on steps must be glued fully, or it slides.
- Repairs. Patching a burnt or torn spot means gluing a new piece in.
- Not for loose-lay rugs and tiles. Rugs and click-together tiles are made to lift. Don't glue them.
Do you need glue for artificial grass seams? On a permanent lawn, yes, in most cases. Self-adhesive tape exists, but glue gives a stronger, longer-lasting join on large lawns.
Can you glue artificial grass to concrete? Yes. Use an outdoor turf adhesive and leave drainage gaps, or water will pool under the turf. See faux grass on concrete.
Which type of adhesive?
Bucket glue suits long seams; cartridges suit edges and repairs.
| Type | How you apply it | Best for | Watch out for |
|---|---|---|---|
| One-part polyurethane, bucket | Notched trowel onto tape or surface | Long seams, full glue-downs | Messy; work fast before it skins |
| Cartridge or tube | Caulk gun or squeeze nozzle | Edges, short seams, repairs | Thick products need a strong gun |
| Latex (SBR), bucket | Trowel | Indoor and covered outdoor surfaces | Less suited to wet, exposed lawns |
| Two-part | Mixed on site | Pro sports and commercial | Not for DIY |
Is polyurethane turf glue best? For outdoor lawns, usually yes. One-part polyurethane cures with moisture in the air, bonds well and resists weather. Applied correctly, it lasts for years.
Bucket glue or cartridge? Buy bucket glue for any lawn with long seams. Buy cartridges for edges, steps and patches. One buyer of a thick tube adhesive noted it needed a strong caulk gun, so check what the product calls for.
The 5 best faux grass adhesives
These five adhesives cover big seams, edges and quick fixes.
1. Grassline Solutions Synthetic Grass Adhesive — Best Glue for Seams
Type: single-part polyurethane | Size: 1 gallon | Colour: green | Bond time: 20 to 30 minutes (seller-listed)
For seams, you want a single-part polyurethane that's green, so any squeeze-out hides in the blades.
Grassline's adhesive is a one-part polyurethane, so there's no mixing. Open the bucket and spread. The seller lists a 20 to 30 minute bond time, which gives you time to position a long seam before it grabs. Green colour means any glue that shows between blades blends in. It's labelled for indoor and outdoor use and as waterproof.
But it's a newer listing with little buyer feedback yet, for a product you'll rely on for years. NexGen Lawns recommends Mapei's Ultrabond Turf adhesives, which are sold through flooring and turf dealers rather than Amazon, if you want a long-established pro brand.
Our take: from our hands-on work with artificial grass, green glue is worth insisting on; any squeeze-out of a pale glue shows as a light line between blades that's hard to hide once it cures.
2. ROBERTS 6700 Indoor/Outdoor Adhesive — Best for Concrete, Decks and Indoor Turf
Type: SBR latex, solvent-free | Size: 1 gallon | Compatible: most indoor and outdoor carpet and turf backings (seller) | Extras: Microban protection
Next, on a hard surface, you're gluing the whole turf down, not just a seam. That needs a well-proven adhesive.
ROBERTS says its 6700 adhesive works with most indoor and outdoor carpets and turf, including rubber, foam, marine and urethane backings. It's solvent-free SBR latex, which ROBERTS says gives high early grab strength. It lists decks, sunrooms and basements among its uses, and adds Microban protection to help prevent stains and odours. It's also the longest-established adhesive here, with the most buyer feedback behind it.
It's our pick for turf on concrete patios, decks and indoor floors.
But latex isn't ideal for exposed lawn seams that stay wet. For seams on soil, use #1.
Our take: in our experience laying turf on hard floors for event stages, an early-grab glue is what stops the turf creeping as you roll it out; slow-grab glues let it shift and leave ripples.
3. Threlaco Turf Glue, 10 oz Tube — Best for Edges and Small Repairs
Size: about 300 ml (10 oz) per tube | Colour: green | Open time: 5 to 10 minutes to position (seller-listed) | Packs: 1 or 12 tubes
Meanwhile, a lifted corner doesn't need a gallon of glue. It needs one tube.
Threlaco's tube comes with a nozzle, so you can run a bead along an edge or under a patch. The glue is green, so it won't stand out. Threlaco says you have 5 to 10 minutes to position the turf before it sets, and that it holds even on damp surfaces. It's sold singly or in 12-packs for bigger jobs.
But tubes are expensive per ounce for full seams. Use them for edges, steps and patches. See our repair guide.
Our take: a nozzle tube is what we'd reach for on a lifted corner; it puts a thin bead exactly where it's needed, so the edge lies flat without stiff, glued-down blades.
4. Linghou Self-Adhesive Seam Tape — Best Glue-Free Seaming Option
Size: 6 in × 33 ft | Type: self-adhesive | Includes: utility knife
Not every seam needs a bucket of glue. On small jobs, sticky tape is far less mess.
Linghou's 6 in tape is self-adhesive: peel off the backing, lay the two turf edges on it and press. The seller says no extra glue is needed and includes a utility knife for cutting it. That makes it a good fit for small lawns, pet runs and rugs that you might lift one day. It's also a long-running listing with plenty of buyer feedback.
But self-adhesive tape is weaker than tape plus glue in heat and wet. For a large permanent lawn, use tape with #1. See our seam tape guide.
Our take: for turf that gets laid and lifted, like event floors and rugs, peel-and-stick tape is the cleaner choice; it holds edges together without leaving cured glue on the backing.
5. ProGrass Turf Adhesive (Lowe's) — Best Big-Box Option
Type: turf adhesive | Use: seams, with seam cloth (seller) | Sold by: Lowe's (non-affiliate)
Buying turf at Lowe's? The matching adhesive is on the same aisle.
Lowe's sells ProGrass turf adhesive alongside its ProGrass turf range. Lowe's notes it's used with seam cloth, so buy the two together. Picking up turf, tape and glue in one trip is handy for a weekend install.
So it's the easy option if you're already shopping there.
But it isn't on Amazon, and the listing gives less detail on bond time than the Amazon picks. Check the label for cure time and temperature limits before you start.
Our take: buying glue and turf from the same range takes the guesswork out of backing compatibility, which is the detail most first-time installers miss.

How do you apply turf glue?
Use less glue than you think; excess oozes up and mats the blades. Here's how:
- Check the weather. Glue needs dry conditions and a temperature within the maker's range. Don't glue before rain.
- Lay the tape rough side up. Seam tape has a rough side for glue. Place it centred under the seam line.
- Spread a thin, even layer. Use a notched trowel for bucket glue, or a steady bead from a tube. Cover the tape where the turf will sit, not beyond it.
- Wait if the label says so. Some glues need a few minutes to get tacky before you lay the turf.
- Lay the edges. Fold both turf edges down onto the glue, butted tight, with no gap and no overlap.
- Keep blades out of the glue. Pull blades upward along the seam as you press. Trapped blades show as a flat line.
- Press and weight. Press the seam firmly along its whole length, then weight it with bags of infill or boards while it cures.
How much glue do you use on a seam? Enough to cover the tape in a thin, even layer, but not so much that it squeezes out when you press. If glue appears between the blades, you used too much. See our seam tape guide.
Adhesive questions
These are the glue questions installers ask most.
How long does turf glue take to dry? It varies by product, temperature and humidity. Some set in minutes; full cure can take a day or more. Follow the label, and keep off the seam until it's cured.
How do you remove glue from turf? Wipe wet glue off straight away with a cloth. Once it cures, polyurethane is very hard to remove. Some installers use mineral spirits on fresh glue, but test it on a hidden piece first, as solvents can damage turf fibers.
Will glue damage a deck? It can. Glue is permanent and can trap water against boards, and gluing may void a deck warranty. Consider loose-laying, or fixing turf only at the edges. See faux grass for decks.
