The passage of time, continuous use, and constant exposure to inclement weather are the greatest enemies of any sports surface. However, when it comes to porous concrete tennis courts—commonly known as TennisQuick courts—wear and tear doesn’t just affect the visual appeal of the game; it directly impacts the ball’s bounce, the traction of players’ shoes, and overall safety, significantly increasing the risk of slips and falls.
Whether you manage a sports club, are responsible for a school’s facilities, administer a homeowners’ association, or own a private court at home, you’ve likely asked yourself the big question: Is it necessary to build a new court from scratch, or can it be restored to its original splendor? The answer is a resounding yes: a comprehensive restoration—involving a deep technical cleaning, an advanced biocide treatment, and a coating of highly specialized paints—can completely rejuvenate the surface, restoring its mechanical properties and grip to what they were on day one.
At Reindesa Instal·lacions Esportives, we are fully aware that a Tennisquick or Tennisfast court cannot be treated like a generic industrial floor. It requires a meticulous approach, carefully controlled timing, and a specially formulated material. Below, we’ll share part of our professional process for repainting and restoring a tennis court to like-new condition—a turnkey service we complete in a record timeframe of 2 to 3 days throughout Spain, with a special focus on and immediate availability in Catalonia.
Why does tennisquick require such specific maintenance and paint?
Porous concrete, or TennisQuick, is an exceptional surface for playing tennis thanks to its extremely high drainage capacity. Its interconnected internal structure allows rainwater to drain vertically almost instantly, completely eliminating puddles and making it possible to play tennis just a few minutes after a downpour has stopped.
However, that same structural strength is its Achilles’ heel if it is not properly maintained. The pores in the concrete tend to accumulate dust, leaf debris, dirt, and, above all, trapped moisture. This combination creates the perfect ecosystem for the proliferation of microorganisms: fungi, moss, and microscopic algae that colonize the surface. The result is a court that loses its original color, becomes dark, and—what is truly dangerous—develops an extremely slippery texture.
To fix this, it’s not enough to simply apply a superficial coat of paint that you buy at any big-box home improvement store. If you apply an unsuitable paint or standard acrylic paint to a porous surface, you’ll seal the pores of the surface, completely destroying its drainage properties and causing the paint to crack and peel within a few months due to pressure from the underlying water vapor. A coating is required that is 100% permeable to water vapor but highly resistant to mechanical abrasion.
The secret behind Reindesa Instal·lacions Esportives: custom-made paints with no commercial inventory
In our commitment to providing exceptional durability, at Reindesa we do not carry a stock of commercial paints that have been stored in warehouses for months. Our Tennisfast court paints are so highly specialized that they are manufactured on demand, specifically formulated and exclusively tailored for each of our projects. This ensures that the resins retain all their chemical properties—including flexibility, adhesion, and UV pigmentation—at the time of application.
The Professional Process at Reindesa Instal·lacions Esportives, Step by Step
To achieve a flawless finish that extends the surface’s lifespan for years, we follow a rigorous protocol divided into key phases. Each step is designed to preserve the substrate’s porosity while maximizing the adhesion of the new coating.
Phase 1: Surface Preparation and Thorough Technical Cleaning
It is impossible to paint successfully on a contaminated surface. The first step is a thorough cleaning using regulated high-pressure water jets. This isn’t simply a matter of “wetting the surface”; we precisely calibrate the pressure to remove embedded dirt, compacted dust, and remnants of old paint that has already deteriorated or flaked off, without eroding or damaging the concrete substrate.
Phase 2: Preventive and curative antifungal treatment (biocide)
Even after high-pressure cleaning, fungal spores and moss roots remain invisible within the microcracks and pores of the pavement. If paint is applied directly over them, the microorganisms will regrow from the inside, pushing against the paint and inevitably causing it to peel. At Tenis Reindesa, we apply a powerful, broad-spectrum antifungal and anti-algae chemical treatment. This product penetrates the porous structure of the TennisQuick surface, neutralizing any organic residue and preventing regrowth in the short and medium term.
Phase 3: Application of the specialized paint for TENNISFAST
Once the surface is perfectly clean, decontaminated, and completely dry, the moment of truth arrives. We apply successive coats of our pure acrylic resins, specifically formulated for porous concrete. The application method uses specialized mechanical or manual systems (such as high-precision rubber squeegees or airless sprayers) that ensure even color distribution without clogging or sealing the pores of the pavement. This maintains 100% water permeability while providing exceptional resistance to wear and tear from gameplay and solar radiation.
Phase 4: Marking and Official Laying Out of Game Lines
The finishing touch is the marking and painting of the regulation lines (baseline, sidelines, service line, and center net). We use road and sports marking paint in a dazzling optical white, formulated with anti-slip microspheres to ensure that the ball bounces exactly the same on the line as it does on the rest of the court, guaranteeing strict compliance with International Tennis Federation (ITF) regulations.
