01 · Project overview

What is this project?

Industrial Metal Cool Roof in Palma, 1,800 square metres in 2023. España – Baleares. The products on the job are Impermax Polyurea H Flex. The Balearic sun and the salt in the air are the two things a finish has to live with, every season.

Project case study Industrial Metal Cool Roof in Palma Nova, Mallorca This industrial metal cool roof project in Palma covers a private building in Palma Nova, Mallorca.

Finally, they rolled on Colodur in RAL 9003 white.

The roof covers about 1,800 m², finished in August 2023.

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?

A roof is a field of outlets, laps and edges, and the weather works on all of them. Water does not leak through the middle of a sound bay. It gets in where the detail was thin or where the deck has started to move.

Industrial Metal Cool Roof in Palma has to be closed as one system, details first, and then left to do its job without a second visit every summer. Across 1,800 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: Impermax Polyurea H Flex. It is chosen because it matches the substrate and the exposure, not because every building wants the same can.

On a roof the membrane has to follow outlets and upstands at the same thickness as the field. An exposed aromatic film takes a topcoat if the colour will be seen.

04 · Application

How is the system built?

The products named for Industrial Metal Cool Roof in Palma are applied as one build-up, details before the field. Outlets, edges and changes of plane are closed first, with the same materials as the main area. A system that changes product at the difficult line is a system with a future peel.

The line is Impermax Polyurea H Flex. The deck is dry, the temperature is inside the range that product allows, and the next coat follows while the window is open. Leaving a detail for the following week is how these jobs come back.

On Industrial Metal Cool Roof in Palma the roof fails at the edge long before it fails in the field. Parapets, outlets, plant plinths and laps are detailed first, with the same system, at the same thickness. A bay can be perfect and the ceiling still stains if the outlet was a collar of mastic.

The deck moves between the hot afternoon and the night. The membrane has to move with it. A rigid coat maps every crack in the substrate onto the ceiling. Thermal movement is the reason an elastic system is on a roof like this, not a preference for a particular can.

Where the film stays in the sun, colour and waterproofing are two layers. The membrane keeps the water out. An aliphatic coat keeps the appearance. Skipping the topcoat because the membrane is already waterproof is how a sound roof starts to look failed, and then gets recoated for the wrong reason.

05 · Results

What does a job like this stand behind?

Industrial Metal Cool Roof in Palma 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 1,800 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 Industrial Metal Cool Roof in Palma 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.
