JUTAgrass Maintenance Manual

Wear and tear and expected lifetime
As with all products, JUTAgrass® is subject to wear. Its expected lifetime depends on the intensity of use, and the effects of local climatic conditions. The more the turf is used, the faster it gets worn. Intensity of wear is a combination of several factors such as hours of use a day, number of participants playing on the surface, type of sport, game, and type of footwear used.

Further factors, which can affect the lifetime of JUTAgrass®:

fiber type (type of polymer, width)
density of artificial turf (number of stitches or actual weight)
production quality of artificial turf
type of infill sand or quality of granulate
the depth of infill and the height of exposed grass fibers
quality of installation
maintenance of the artificial turf

Instructions for using JUTAgrass® artificial turf

A new artificial playing surface can be used immediately after the infill installation is complete. Ball bounce and rebound will improve over time depending on the intensity of use. During the initial phase of post-installation, the more often and intensive use, the quicker the ideal ball performance and surface playability is reached.

Depending on intensity of use, the artificial turf surface should be regularly brushed and filled with infill when and where required to maintain optimal performance. This is particularly important during the first months of use. The volume of infill depends on user requirements with regard to degree of traction and sliding desired. Infill affects several surface properties relative to player interaction and ball behavior. For example, sand infill is of particular importance for ball bounce for tennis and likewise elastomeric infill of particular importance for traction.

Athletes should always use sports footwear on the artificial turf surface. The footwear must be clean, free of mud, stones and other dirt which could become mixed with the silica sand infill, compromising the quality of the surface. For football it is recommended – standard 12-14 studs football boots, standard 45-60 mini-studs boots, standard blade boots and standard 6 studs boots (only with plastic studs). We do not recommend use of – standard 6 studs boots with metal studs and spiked athletic running boots. It is not appropriate to cycle on the turf surface, braking abruptly and skidding. The surface can also be damaged by a falling bicycle, falling objects, or similar. It is forbidden to slide heavy objects or apparatus on the turf, or place them permanently without using a protective pad.

In the case of any damage or premature wear under the warranty period, the manufacturer is to be informed in writing. Repairs are not to be made by the facility owner or any unauthorized repair service. Improper repairs during the warranty period will invalidate the warranty.

It is necessary to remove fallen leaves and debris promptly from the surface to prevent contamination of the turf and infill from rotting or decaying materials. To remove fallen leaves, we recommend a power blower with electric or petrol motor. The surface will inevitably become somewhat contaminated by industrial pollutants present in the atmosphere and rainwater. If sprouting weeds or moss appear on seldom used or shaded areas of the playing surface, appropriate chemical agents are to be used which will not damage the artificial turf system, elastic underlayment or sub base. (e.g. Roundup). When the playing surface is situated in a continuously shaded area or in an often humid area, weeds or moss may grow after several years of use. It is recommended that all unwanted weeds and/or moss are removed with the agent FLORIA (Mech-stop) in the summer by watering or spraying according to the manufacturer’s instructions (max. two applications, interval of 2-4 weeks).

In the case of playing surfaces with fully permeable granular sub-surfaces, it is necessary to firm up the surface during spring maintenance with a medium to heavy hand-operated roller (150 – 200 kg) or with a mechanical roller without vibration. The playing surface will get firmer immediately.

If normal turf maintenance is neglected or the playing surface is subjected to intense use, it can lead to severe pollution by dust, mud, molding organic substances etc. These substances can consolidate and solidify. This creates a “crust” or in the extreme, nearly a concrete-type surface. In this instance, a full refurbishment of the artificial turf system is necessary by using special machines. Modern refurbishing technologies are both effective and turf system-friendly. After a thorough and complete cleaning of the turf, the infill is re-filled and the grass fibers are again in a vertical position.

Observance of these instructions on the part of the user is a condition of the limited product warranty from the moment of delivery, through installation to the end of the warranty period of the JUTA a.s. company.

Maintenance

It is incorrect to assume that an artificial turf surface does not require maintenance. Every artificial turf system requires maintenance, although less than natural grass. A proper maintenance program can prolong the lifetime of artificial turf. Artificial turf maintenance as such is very specialized and difficult to generalize. There are plenty of factors, which determine the type and frequency of maintenance, for instance:

playing surface construction, sub-surface and surroundings
weather conditions: humidity, dryness, high or low temperature
frequency and intensity of use: hours per day, number of players etc.
Depending on the frequency, we recommend the following maintenance:

Daily – weekly – caretakers of the sports field are to: brush the surface, collect trash, clean the access and surrounding area of the playing surface, small repairs:
brushing – regular maintenance of the surface with particular attention to sand or granulate. Specific brushes for artificial turf are to include several brushes at different angles, rotating stiff brushes, etc.
filling – to keep infill even and therefore permeable, cosmetic maintenance of the surface
Annual – professional – cleaning with power blower, infill replacement, major repairs. When daily-weekly maintenance is ignored, annual maintenance becomes far more expensive. Annual maintenance is to be performed by specialized contractors with all the appropriate equipment.
Maintenance procedures of artificial turf continue to evolve and improve. For this reason Juta a.s. does not recommend a specific type of maintenance or maintenance schedule in this manual. Most installation companies possess very detailed information regarding the maintenance of different types of areas in addition to information available from those companies who specialize in maintenance. A maintenance schedule is generally custom designed to suit individual requirements.
