About the product
Aguaplast White Waterproofing Spray is a rubber-based aerosol waterproofing product, ready to use without preparation. It seals and waterproofs any surface in seconds with a single pass.

Its white finish can be repainted with any plastic paint. Fast drying, high flexibility, and easy application and repainting. 400ml format.
What uses and surfaces is it ideal for?
- ✓ Sealing and waterproofing of terraces, balconies, and roofs — joints and water points
- ✓ Sealing of metal or plastic pipes, drains, and PVC tubes
- ✓ Protection and waterproofing of interior and exterior wood — tables, chairs, benches, structures
- ✓ Repair of roofs and areas with high humidity
- ✓ Sealing of cracks and joints in facades, walls, and vertical surfaces
- ✓ Protection of metal areas exposed to rain or permanent humidity
Why choose Aguaplast Waterproofing Spray
- ✓ Ready to use in spray format — no preparation, mixing, or tools required; shake and apply directly from the bottle; ideal for quick spot repairs without setting up a complex waterproofing system
- ✓ High sealing and waterproofing power — the rubber base creates an elastic and waterproof membrane that seals joints, cracks, and water entry points, even on irregular surfaces
- ✓ Good flexibility — the cured membrane is elastic and accommodates substrate movements (thermal expansion, small deformations) without cracking or detaching
- ✓ Fast drying — dries quickly, allowing for agile work and the application of a second coat or painting over on the same day
- ✓ Repaintable with plastic paint — once dry, it can be painted over with any plastic paint to integrate the color with the surroundings without the repaired area being visible

How to apply — in 3 steps
- Prepare the surface: clean the area to be treated, removing dust, grease, and loose particles. The surface can be slightly damp but not waterlogged. For repairs on joints or cracks, remove loose material or degraded old sealant.
- Shake well and spray: shake the container vigorously for 2 minutes. Apply at a distance of 20–30 cm in uniform coats, thoroughly covering the area to be treated. For greater thickness and waterproofing, apply several crossed coats, allowing drying time between them.
- Allow to dry and repaint if necessary: once dry, the surface is waterproofed and ready. To integrate it with the surrounding color, apply plastic paint over it once the spray has completely dried.
For greater effectiveness on joints and cracks, apply several coats. Use in a ventilated area. Do not apply on surfaces in contact with potable water.
