Miguel Hernandez medical school, Alicante
In 2021, Miguel Hernandez medical school, Alicante was made with Rayston Spray D50.
01 · Project overview
What is this project?
In 2021, Miguel Hernandez medical school, Alicante was made with Rayston Spray D50. The Mediterranean coast here is mild until the summer sun sits on a roof all afternoon.
This one is secondary containment.
Krypton Chemical makes the resin. The crew on site applies it. On Miguel Hernandez medical school, Alicante the details have to get the same film as the open field, and the cure has to finish before the building goes back to work.

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.
Miguel Hernandez medical school, Alicante has to be closed as one system, details first, and then left to do its job without a second visit every summer.
03 · The solution
Which system was trusted here?
The system trusted here is the one named for the job: Rayston Spray D50. 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 Miguel Hernandez medical school, Alicante 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 Rayston Spray D50. 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 Miguel Hernandez medical school, Alicante 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?
Miguel Hernandez medical school, Alicante 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.
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 Miguel Hernandez medical school, Alicante 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?
Miguel Hernandez medical school, Alicante. España – Comunidad Valenciana
When was the work done?
2021.
Which products were used?
Rayston Spray D50.
Why are the details done first?
Outlets, upstands and joints are where water gets in. They are closed with the same system as the main area.
Where do the cure times come from?
From the product data sheet. They describe the resin, not a clock stopped on this site.
The programme does not change because the building is smaller or further away. Prepare the substrate until it will hold the system, close the details before the field, and keep the thickness honest at every edge. A second visit to repair a starved detail costs more than doing that detail on the first day. Miguel Hernandez medical school, Alicante is held to that standard. Krypton Chemical supplies the resin. The applicator owns the surface.
