Best Artificial Grass Seam Adhesives and Tapes for Turf Projects
The right artificial grass seam adhesive depends on how you plan to join the turf: liquid glue is applied to a seam or joining surface, while self-adhesive tape sticks to the turf backing. Threlaco’s two-tube set is best for a smaller glue-based job, and its four-tube set provides more adhesive for a larger project. GripSeam is a single-tube option, while TYLife and WELSTIK are tape choices for buyers who prefer peel-and-stick application.
| Product | Format | Best For |
|---|---|---|
| Threlaco 2 Tubes | Liquid adhesive | Smaller seam jobs |
| GripSeam | MS polymer adhesive | Single-tube application |
| TYLife Seaming Tape | Self-adhesive tape | Quick, no-liquid application |
| Threlaco 4 Tubes | Liquid adhesive | Projects needing multiple tubes |
| WELSTIK Seam Tape | Self-adhesive tape | Outdoor and pet-use areas |
Threlaco Two-Tube Turf Glue
This set includes two bottles, each listed as approximately 300 ml or 10.15 ounces, with glue heads for application. The manufacturer describes the adhesive as green and says it bonds artificial grass seams, including on wet surfaces.
Best for: DIY installers who need a modest supply of liquid adhesive and want to apply glue directly along a seam. The listed directions call for cleaning away oil and debris, applying the glue, pressing the seam together, and optionally using a weighted roller.
Keep in mind: The instructions give a 5-to-10-minute window to position the turf before the glue dries. Plan the alignment before applying adhesive, and follow the product directions for pressing or rolling the seam.
GripSeam MS Polymer Adhesive
GripSeam is a 290 ml tube of MS polymer adhesive for synthetic grass surfaces. Its listed features include application to jointing tape or solid surfaces, bonding on wet surfaces, fast tack, and rapid curing.
Best for: Buyers who want one tube of adhesive and need a product described for use with either jointing tape or a solid surface. Its fast tack may suit installers who can position the materials promptly.
Keep in mind: The supplied details do not specify coverage or a working-time window. Check the product instructions to confirm the amount needed and how quickly the seam must be positioned.
TYLife Self-Adhesive Seaming Tape
This tape measures 6 inches by 32.8 feet and uses a non-woven fabric base. The listed method is to measure and cut the tape, remove its PE film, and attach it to the back of the synthetic grass. The product description says it is waterproof.
Best for: Installers who prefer peel-and-stick tape instead of applying liquid glue. It is described for joining two pieces of artificial grass and may be useful where a tape backing is preferred.
Keep in mind: The instructions specify attachment to the turf’s back. Check the turf backing and installation directions before choosing tape, and position the seam carefully before pressing it down.
Threlaco Four-Tube Turf Glue
This pack contains four bottles, each approximately 300 ml or 10.15 ounces, according to the listing. The green liquid is intended for artificial grass bonding, and the product description claims strong adhesion, including on wet surfaces. The listed application steps include cleaning the area, fitting the glue head, applying adhesive, and pressing or rolling the seam.
Best for: Larger jobs or buyers who want several tubes available for multiple seams. It has the same stated application process as the two-tube Threlaco set, with more tubes in the package.
Keep in mind: The instructions advise arranging the turf within 5 to 10 minutes after application. The listing does not provide a coverage estimate, so plan supplies based on the project and product directions.
WELSTIK Heavy-Duty Turf Seam Tape
WELSTIK’s self-adhesive tape measures 6 inches by 33 feet. The manufacturer describes it as waterproof and UV-resistant, and lists use for lawns, putting greens, patios, and pet runs. Its description also states an operating temperature range from 150°F to -20°F.
Best for: Buyers choosing tape for an outdoor area exposed to sun, rain, or regular pet activity. The listed weather and moisture features make it a relevant tape option for those conditions.
Keep in mind: The listing does not explain every surface or turf-backing requirement. Confirm that the tape suits the intended installation before applying it across a long seam.
Buying Guide: How To Choose Turf Seam Adhesive
Should you choose glue or seam tape?
Choose liquid adhesive if you want to apply glue to the seam or a joining surface and can follow its positioning and pressing instructions. Choose self-adhesive tape if you prefer to measure, cut, peel, and attach a strip to the turf backing. These are different application methods, so check the turf and installation instructions before buying.
How much adhesive or tape does the project need?
Compare the package size with the number and length of seams. The Threlaco options contain two or four tubes, while GripSeam is listed as one 290 ml tube. TYLife tape measures 32.8 feet, and WELSTIK tape measures 33 feet. The provided details do not state adhesive coverage, so do not assume a specific number of seams per tube.
What matters for outdoor installation?
Look at the features tied to the installation environment. GripSeam and both Threlaco listings describe bonding on wet surfaces; TYLife is described as waterproof; WELSTIK is described as waterproof and UV-resistant. These are product claims, not a substitute for checking the instructions, site conditions, and turf manufacturer’s guidance.
How can you reduce visible or uneven seams?
Measure and align the turf before bonding. For Threlaco glue, the listed instructions recommend a clean area without oil or debris and pressing the seam so both surfaces make contact. A weighted roller may be used. For tape, measure and cut before removing the film, then position it along the turf backing as directed.
Frequently Asked Questions
Can artificial grass seam adhesive be used on wet surfaces?
The GripSeam and Threlaco listings state that their adhesives can bond on wet surfaces. Follow each product’s instructions and do not assume every turf surface or installation condition is suitable.
Is turf seam tape the same as liquid adhesive?
No. Liquid adhesive is applied to a seam or joining surface. Self-adhesive tape has a peel-off film and is attached to the turf backing.
How long do you have to position Threlaco turf glue?
The Threlaco instructions say to position the turf before the glue dries, within 5 to 10 minutes, then press or roll the seam again.
Which option is better for a larger project?
The four-tube Threlaco pack provides more tubes than the two-tube set. The listings do not give coverage per tube, so estimate needs from the project plan and product directions.
