About the product
Aguaplast Black Waterproofing Spray is a ready-to-use aerosol waterproofing spray with a black rubber base that seals and waterproofs any surface in seconds. Ideal for roofs, gutters, drains, and pipework where black is the standard color and no repainting is intended. The rubber base creates an elastic, waterproof, and flexible membrane that seals joints, cracks, and water entry points. Fast-drying, high sealing power, and paintable with any plastic paint if needed. 400ml format.
What uses and surfaces is it ideal for?
- ✓ Sealing and waterproofing of flat and pitched roofs
- ✓ Gutters, downspouts, and drains — sealing of joints and leak points

- ✓ Terraces and balconies — sealing of joints and specific areas with water ingress
- ✓ Facades and walls — sealing of cracks and joints in exteriors
- ✓ Industrial installations and metal structures exposed to rain
Why choose Aguaplast Black Waterproofing Spray
- ✓ Black color — the standard for roofs and coverings — black is the usual color for roofs, gutters, drains, and industrial installations; the repair is visually integrated without the need for repainting
- ✓ Ready to use in spray format — requires no preparation, mixing, or tools; simply shake and apply directly; ideal for quick spot repairs on roofs without setting up a complex 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 or damp surfaces
- ✓ Good flexibility — the cured membrane is elastic and adapts to substrate movements without cracking or detaching; especially important on metal roofs with large temperature variations
- ✓ Fast drying — allows for agile work and the application of several cross-coats in the same day to achieve the necessary waterproofing thickness

How to apply — in 3 steps
- Prepare the surface: clean the area, removing dust, grease, and loose parts. For joints and cracks, remove degraded old sealant. The surface can be slightly damp but not waterlogged.
- Shake well and apply: shake the can vigorously for 2 minutes. Apply from 20–30 cm away in even coats, covering the area well. For greater effectiveness, apply several cross-coats, allowing each coat to dry in between.
- Allow to dry: once dry, the area is waterproofed and ready. If a color change is desired, it can be repainted with plastic paint once completely dry.
Use in a ventilated area. Apply several coats for greater waterproofing. Do not apply on surfaces in contact with drinking water.
