01 · Project overview

What is this project?

Rooftop Sports Court Flooring on a Supermarket in Montcada, 1,345 square metres in 2022. España – Cataluña. The products on the job are Floortop 1K. Catalonia works a roof and a floor hard: sea air on the coast, a sharp swing between afternoon and night, and industrial towns that do not stop for a slow coating.

In August 2022, PAVINCAS 2002 SL resurfaced two courts of 1,345 m² and 475 m².

The system was Rayston Floor PU 10 Sport, built on Floortop 1K.

As a result, the red surround looked patchy, and the grey court had lost its lines.

Krypton Chemical supplies the resin system. The duty is ordinary and strict: keep water, wear and weather on the right side of the structure, and do it in the details as well as in the open field.

02 · The challenge

What did this structure ask of the system?

Rooftop Sports Court Flooring on a Supermarket in Montcada is a working floor. Wheels, washing water and the daily grit of a building all sit on the same film. A coating that only looks right on the day it is laid will map every crack in the slab within a season.

The concrete has to be opened, not painted over. Laitance, oil and old dust are how resin floors lose their bond, and they lose it in the traffic lines first. Joints and drains are details, not the edge of the job. Across 1,345 square metres, a thin spot is not a small repair.

03 · The solution

Which system was trusted here?

The system trusted here is the one named for the job: Floortop 1K. It is chosen because it matches the substrate and the exposure, not because every building wants the same can.

A floor system is a stack. Primer for the bond, body for the thickness, seal for the face. Skipping the primer to save a day is how the floor comes back up on the tyres.

04 · Application

How is the system built?

On this floor the sequence follows the products named for the job: Floortop 1K. The slab is ground or blasted, the dust is lifted, and cracks are filled before the first resin. A primer is what locks the system into the pores. The body coat takes the wear. The seal is the face people walk on, and it is the layer that has to keep its colour.

Each coat has to be down at the thickness that product is designed for, including at the drains and the joints. A floor that is thick in the middle and starved at the edge will fail at the edge. Traffic waits until the seal has cured. Washing water waits longer than footsteps.

On Rooftop Sports Court Flooring on a Supermarket in Montcada the floor is not a decorative coat. It is the surface the building works on. Preparation decides it. Oil, laitance and a closed power-floated face will take a primer for a week and then let it go. The mechanical opening of the pores is part of the system, not a favour the applicator adds if there is time.

Joints move. A resin that is rigid across a joint will crack there, and the crack fills with wash water. The joint is either honoured, with a flexible seal of the right width, or the floor design accepts a cut. Drains are turned into the floor, not left as a ring of mastic after the last coat. Colour goes in the seal coat so a repair later can be matched, and so daylight and cleaning chemicals meet a film that was chosen for that, not the structural coat underneath.

Cure is part of the programme. Foot traffic, pallet trucks and the first wash are three different dates. Opening a floor early because the building is in a hurry is how a good system gets a bad name. The data sheet of each named product sets those dates. This page does not invent a shorter one for the sake of the story.

05 · Results

What does a job like this stand behind?

Rooftop Sports Court Flooring on a Supermarket in Montcada has one standard. The coating is still doing its job after the building is back in use, at the details as well as in the middle. The area on this job is 1,345 square metres.

Figures for cure, thickness and strength, where they are given, come from the product data sheets. They are not a test cut out of this building.

What this asks of Rooftop Sports Court Flooring on a Supermarket in Montcada is workmanship at the difficult line. The open field is the easy part of a resin job. Outlets, edges, penetrations and changes of plane are where thickness goes missing, and where water or wear finds the gap. The same products and the same care belong there, and the cure is allowed to finish before the building goes back into use. That is the difference between a coating that was simply applied and a system that stays in service.

Frequently asked questions

Where is this project?

Rooftop Sports Court Flooring on a Supermarket in Montcada. España – Cataluña

When was the work done?

2022.

Which products were used?

Floortop 1K.

Why does the concrete preparation matter?

Resin sticks to a clean, open slab. It does not stick to laitance or oil. The bond fails in the wheel tracks first.

When can the floor take traffic?

Foot traffic waits until the seal has cured. Wheels and wash-down wait longer. The exact window is the one in each product’s data sheet.
