Namgrass Adhesive is a Multi Purpose Adhesive for joining artifical grass. The adhesive is a two component polyurethane based adhesive system primarily designed for bonding artificial grass carpets.
The adhesive should be mixed thoroughly with the Hardener Additive at a ratio of 10:1 by weight by first adding the hardener component to the adhesive component in the plastic tub. Mixing in all cases should be carried out thoroughly by using a mechanical stirrer because poorly mixed adhesive does not cure correctly and remains soft. A mains drill and mixing paddle should suffice to ensure mixing of the two components is complete particularly around the sides and the bottom of the tub.
Before use, individual substrates should be evaluated for bonding performance prior to any large-scale application. Please note that the mixed adhesive should never be applied onto wet substrates because this will affect the curing process and lead to inferior bonding. Despite this reservation the adhesive is tolerant to use in damp weather conditions
The mixed adhesive should be is poured from the tub directly down the centre of the tape, or into a suitable application machine. The adhesive is then spread by notched trowel (this allows the adhesive to stand up in ridges) across a width of 250 mm, leaving a 25mm strip uncoated at each edge of the tape. Sport-Fix Multi Purpose is suitable for bonding all synthetic grass carpets to geo-textile tapes and a mixed set of 11.0 kg will bond down a seam length of 15 to 25metres.
It is important that sufficient adhesive is applied to transfer onto the carpet back when this is pressed into position and should effectively fill the gaps between the stitches. Therefore coverage can be down to 15 m per set on some types of the very long pile carpet. The seam can be lightly rolled after making the joint and subsequently re-rolled when the adhesive is setting to a high viscosity mastic appearance (normally 1 – 2 hours).
Another method commonly used is to hold the seams in place by weighting the carpet with dry sand or planks until the adhesive has cured. The adhesive will normally partially cure in 1 – 2 hours at average spring/autumn temperature
Available in 5kg or 10kg tubs
