Renovating pools, roofs and terraces with a coating that bonds without joints and lasts for decades.

What is polyurea?
Polyurea is a high-quality, seamless coating created by mixing two liquid components under high pressure and spraying them directly onto the surface. Within seconds they form a strong, rubber-like layer that is completely waterproof.
Because the coating is applied in one go, without joints or seams, it forms a closed skin over the entire surface. That layer is exceptionally elastic and crack-bridging: it moves with the substrate without tearing. This is why polyurea is ideally suited to pools, roofs and terraces where water must never find a way in.
Polyurea is applied by specialised professionals using professional equipment. Thorough preparation of the substrate is decisive for the end result and the lifespan.
How the system is built up

Why polyurea?
Polyurea is used worldwide in industry, infrastructure, water reservoirs, car parks and luxury pools. No other coating system combines this adhesion, elasticity and lifespan.
Suitable for renovation and new construction. In many cases polyurea can be applied directly over existing finishes. Available in virtually all RAL colours.

Pool renovation: your pool, better than new
We carry out complete pool renovations on the Costa Blanca. From removing existing tiles to a fully waterproof polyurea finish. The result: a pool that looks like new again and is completely waterproof.
The work we do
- Tile removal
- Crack repairs
- Concrete repairs
- New render layer
- Polyurea finish
- New lighting
- Skimmer replacement
- Inlet jet replacement
- Technical penetrations
- Waterproof detailing
Polyurea over existing tiles
In many cases we work directly over existing pool tiles. After an inspection we determine whether this is technically sound.
- Less demolition work
- Shorter renovation time
- Lower costs
- Faster result
Tiles over polyurea
The look of a tiled pool, combined with maximum waterproofing: first a fully waterproof polyurea system, then new tiling.
- 100% waterproof base
- Extra protection against leaks
- Luxurious appearance
- Longer lifespan for the tiling
A complete renovation takes 5 to 10 working days on average, depending on the condition of the pool and the work chosen.


Polyurea pools
The Costa Blanca is home to hundreds of thousands of pools, a large share of which are older than 15 to 20 years. Many pools struggle with recurring defects and rising maintenance costs.
Polyurea offers a durable, future-proof answer: the strongest waterproofing for your pool, with a 10-year guarantee and an expected lifespan of 25 years or more.
Does this sound familiar?
- Leaks
- Mosaic tiles coming loose
- Cracking
- An ageing finish
- High maintenance costs
Polyurea is the definitive solution: leak-free, low-maintenance and seamless.
Roofs & terraces
Alongside pools, we specialise in polyurea for roofs and terraces. Whether it is a leaking flat roof, a concrete roof terrace or a balcony: polyurea provides a definitive waterproof solution.
A waterproof roof protects the entire structure beneath it. Moisture that gets in attacks concrete, reinforcement and finishes. One seamless, elastic skin over the whole roof surface prevents that permanently.
Roofs
- Flat roofs
- Concrete roofs
- Roof terraces
- Leak renovation
- New-build projects
Terraces
- Balconies
- Roof terraces
- Outdoor areas
- Covered terraces
Finishes
After application, various finishes are possible:
- Tiles
- Decking
- Artificial grass
- Terrace coating
- Natural stone

From inspection to handover
We follow a fixed, proven method. That way you know exactly what to expect and the result stays watertight for decades.
We assess your pool, roof or terrace, on site or from photos, and send a clear, no-obligation quote within 24 hours.
Old layers, cracks and unevenness are repaired. We thoroughly clean and level the surface so the coating bonds perfectly.
We apply a bonding primer of approximately 300 g/m², which creates a lasting, strong bond between the substrate and the polyurea.
We spray-apply a 100% pure polyurea membrane: seamless, without joints, with a final thickness of at least 2 mm, extremely crack-bridging and elastic.
An aliphatic polyaspartic topcoat of approximately 300 g/m² protects against UV radiation and keeps the colour beautiful for years, even in strong sun.
We inspect the work together with you and tidy everything up. You receive a 10-year guarantee on the waterproofing, with an expected lifespan of 25 years or more.
Most projects are completed within a few days.
Technical quality: 100% pure polyurea
We work with a 100% pure polyurea system from a leading European manufacturer. The system is CE certified, holds a European Technical Assessment (ETA) and has a long lifespan of more than 25 years.
The division of roles is clear. The manufacturer develops and produces the technology. SealCraft Iberia is the specialist in its application: assessing the substrate, the system build-up, the application and the service afterwards.

A high-quality system demands high-quality workmanship


The quality of polyurea is decided on the day of application. That is why we leave nothing to chance.
Preparation
The substrate is repaired, cleaned and levelled. A durable coating needs a dry, clean and stable base with the right primer.
Equipment
We spray with professional two-component equipment that mixes both components under high pressure. Only then does a homogeneous, seamless membrane form.
Experience and technique
Layer thickness, temperature and working time all matter. Our experience from more than 20 years in construction and coatings makes the difference between a coating and a system that lasts for decades.
Inspection and finishing
Details around steps, skimmers and penetrations are finished watertight. At handover we inspect the complete work together with you.
