What are primary backing and secondary backing?

In artificial turf, the primary backing and the secondary backing form the structural base on which the fibers are inserted and fixed. They are fundamental layers that determine the long-term stability, durability and strength of the turf.
The primary backing is the first layer – usually woven – where the fibers are sewn together. The secondary backing is the layer that is subsequently applied to seal and reinforce the whole, ensuring that the fibers are firmly attached and that the turf retains its shape over time.

Function of the primary backing

Support for fiber insertion

The primary backing is the fabric where the yarns that make up the artificial turf are needled. It is usually composed of materials such as polypropylene, which offers a stable structure and a good capacity to support the density of the fibers.
A high quality in this layer ensures that the fibers are correctly aligned, distributed and fastened, which directly influences the natural appearance of the product.

Stability and resistance

A well-designed primary backing helps the turf to maintain a uniform base, preventing shifting or deformation. This is especially relevant in frequently used gardens or areas where a stable surface is required for walking, playing or resting.

Function of the secondary backing

Definitive fixation of the fibers

Secondary backing is applied to seal the stitches and protect the bond between the yarns and the primary backing. Typically a compound such as latex or polyurethane is used, which provides a firm and durable bond.
This coating prevents the fibers from shedding over time and improves the turf’s resistance to stress, movement or weather changes.

Structural reinforcement and durability

In addition to its adhesive function, the secondary backing acts as a mechanical reinforcement. It provides firmness, prevents deformation and prolongs the life of the turf even in areas with frequent traffic.
A quality secondary backing also improves drainage capacity, favoring water drainage and keeping the turf in better condition all year round.

Importance of both layers in turf quality

The overall performance of artificial turf depends on the combination of the primary and secondary backing. Together they provide stability, fixation, firmness and durability. When these layers are well designed, the turf withstands daily activity better, retains the verticality of the fibers and maintains its natural look for longer.
