Its 6" x 40 Feet format provides a dedicated strip for seam work, while the nonwoven fabric surface adds texture where the edges meet. The tape uses a butyl adhesive and is designed for indoor and outdoor applications, including artificial grass, turf, mats and carpet seams. ## Key takeaways This is a purpose-made tape for joining or repairing artificial grass, rather than a general-purpose strip being adapted for a lawn seam. The green nonwoven fabric has a textured surface intended to increase friction and help reduce slipping at the join. A paper backing peels away during installation, and the adhesive is applied to the surface on one side of the tape. The butyl adhesive is described as waterproof and weatherproof, with UPF50+ protection intended to help protect the adhesive from ageing caused by sunlight. These features make the tape relevant to both indoor projects and outdoor lawn installations. The product measures 6" x 40 Feet, giving you a defined width and length for planning the seam work. Buyer feedback is positive about the product’s overall quality, while experiences with adhesion and durability are mixed. That makes careful surface preparation and application particularly useful: the joining surfaces should be free of dust and fingerprints before the tape is applied. ## How it fits Use the tape beneath the meeting edges of two pieces of artificial grass, or to repair an existing grass seam. It is also recommended for turf, mat and carpet seams, with cloth and fabric listed as suitable surface types. Its textured nonwoven fabric forms the seam base, the butyl adhesive bonds to the prepared surface, and the lawn edges are brought back over it and aligned. For installation, turn back the lawn edge, peel off the paper backing and place the tape along the edge. Bring the lawn back over the tape, then align the adjoining piece with the first. Take time to position the edges together before pressing them into place. Keep water away from the adhesive during the first 8 hours after application. Compared with adapting a general-purpose tape, this format is specifically intended for turf and grass seams, making it a straightforward choice for planned joins and targeted repairs. ## Best use cases Use LLPT AG640 when laying new artificial grass and you need to connect adjoining sections, or when repairing a separated seam. It also suits projects involving smaller artificial grass mats and carpet or turf joins. The product is presented for home, school, shop and exhibition settings, as well as open spaces such as playgrounds, parks and pool areas. Its indoor and outdoor positioning offers flexibility across different installation settings, while the 6" width gives you a consistent strip to place beneath the join. A practical approach is to prepare and align the edges first, then apply the tape along the seam so the two sections meet over the adhesive. This keeps the tape focused on its intended task: creating a joined surface between pieces of grass or matting. ## When it makes sense Choose this tape when the project calls for a dedicated seam product with a nonwoven fabric surface, one-sided butyl adhesive and a 6" x 40 Feet format. It is suited to joining artificial grass sections or carrying out a seam repair, with additional listed uses for turf, mats and carpet. For installations where the seam needs to be planned as part of a wider lawn or floor covering, its stated indoor and outdoor applications help make it a versatile fit. Prepare the surface, align the edges and allow the adhesive to remain dry for the first 8 hours after application. ## Images ![LLPT AG640 Artificial Grass Seam Tape, 6" x 40 Feet, Butyl Adhesive — 1](https://www.ofertitastop.com/i/yINOJnc0e1Z38FScugkh8-XOov8YlX66xp2BnWX_fF7m9C5z__yQI2UJ0Aoajkf9eSixJi77_djQVYMl_Ks-cBXKm-RGu6HFRAPphsV2eIlgv6nkL01SrpmFng.jpg) ![LLPT AG640 Artificial Grass Seam Tape, 6" x 40 Feet, Butyl Adhesive — 2](https://www.ofertitastop.com/i/GAzxFNz6sxFpnWPbXvFIqmcmL5awMZNnSbBJvr__4IQoaPjzKh6A2LDNgTy68FJ9HwDH1V-uEoOUqET_um5sInLysCJUgnWmpZlJmCsSBJ7Cy1VxJfK31TjAMQ.jpg) ![LLPT AG640 Artificial Grass Seam Tape, 6" x 40 Feet, Butyl Adhesive — 3](https://www.ofertitastop.com/i/RTm3BNuqV3MRHFJU7rlwujSlZqot9CGjSYvmCWfKTrXE5dy3069QOwP_uIN5rMK6LK-j8-yp64KqPpSTBSPcl360j8MIkcEs7McBSkDfFaGUFzIO667nYDDf0w.jpg) ![LLPT AG640 Artificial Grass Seam Tape, 6" x 40 Feet, Butyl Adhesive — 4](https://www.ofertitastop.com/i/xetjtsvZP-vNQI8u_gClWavCVp1ARqFM-_IYBl08KxSyxQiBHLU9yoy4Y_RijiQX7C0bdIswP1KUvtaTqnryuTClOnzXgF6IbZsM2_sPBhCj3JUxLn2cU7R6uQ.jpg) ![LLPT AG640 Artificial Grass Seam Tape, 6" x 40 Feet, Butyl Adhesive — 5](https://www.ofertitastop.com/i/1ua_sxNw8Ll6huDx0feacl5xze1BVQyo9WGC2QEE755QPWrsIObv0bYp42l_H0noaPBD-oKKjgp0bifzn7hEdg7MR4vDcm35BrPOgkbtEB7cQUAlLMQyS-1B5A.jpg)
