Rehabilitation of the paving of a multi-sports court

With the passage of time and the changing habits of an increasingly healthy society, we are faced with the need to find areas where we can practice outdoor sports. Due to the use and the inclemency of the weather, this type of facilities must be kept in perfect conditions.

of use.

For this reason we present the refurbishment of a sports court of 850m2 located in Sant Joan Despí (Barcelona).

Reason for the intervention

The sports court had an old paint coating that was badly worn and cracked and needed to be replaced to restore the functionality of the equipment.

Challenges and constraints

“Remove old coating and degraded parts.

“Choice of a protection and coating product with high resistance to weathering and UV rays to ensure maximum durability of the sports facility.

Molins Solution

“Preparation of the substrate and application of BETOPOX® PRIMER epoxy primer.

“Application of BETOPOL aliphatic polyurethane protective paint.

Functions of the primer in pavements:

Resin-based (usually epoxy) primers perform several important functions in the application of coatings

on pavements:

” Reinforcement and hardening of the surface layer of the substrate

The impregnation of the substrate by means of resin-based primers contributes to improving the characteristics of the

substrate. The resin, pure or with solvent, penetrates the substrate and hardens in the pores of the surface layer.

reinforcing it.

” Increased adhesion of coatings

Priming always improves adhesion, but especially in the case of application of coatings with high

The load content improves the “wetting” effect between the substrate and the coating.

” Pore sealing

This is perhaps the most important function of primers. The primer fills the pores of the substrate and displaces the

The air they contain prevents the appearance of bubbles and craters in the final coating and also avoids excessive absorption of material by the substrate, thus regulating its absorption.

” Protection of the coating against the alkalinity of concrete

Some coatings, such as BETOPOL, are sensitive to the alkalinity of the concrete, i.e. if they are applied directly on a substrate with a high pH such as concrete, they do not harden correctly and do not form a film. In these cases, the use of a primer is essential.
