The 300ml black sealant is an advanced, high-performance, one-component elastic adhesive and sealant, specifically designed to meet the most demanding needs in construction, industrial, automotive, and advanced DIY projects. Thanks to its advanced moisture-curing technology, this product reacts with ambient humidity to form a flexible, durable, and high-strength bead, making it the ultimate solution for sealing joints and bonding multiple materials.

This elastic sealant stands out for its excellent adhesion to a wide variety of surfaces without the need for a primer. It is suitable for application on concrete, brick, metals such as steel and aluminum, wood, ceramic, glass, and various synthetic materials. Its formulation guarantees high resistance to weathering, ultraviolet (UV) rays, aging, and the action of various chemicals, ensuring that joints maintain their watertightness and elastic properties over the years, both indoors and outdoors.

The versatility of this black putty allows for simultaneous sealing and structural bonding with a single application. It effectively absorbs vibrations, impacts, and thermal expansion or contraction of the bonded materials, preventing cracks and water or air leaks. Its thixotropic texture facilitates easy extrusion and clean application, without sagging even when applied to vertical surfaces or ceilings, achieving professional, aesthetically pleasing, deep black finishes.

Frequently Asked Questions

On what surfaces can this black putty be applied?

This adhesive and sealant is suitable for a wide variety of construction and industrial materials, including concrete, mortar, stone, brick, metals (steel, aluminum), wood, glass, tiles, and numerous plastics. Its high, multi-purpose adhesion allows for easy fixing and sealing.

Can it be painted once it's applied and dry?

Yes, once the product has completed its moisture curing process, the putty can be painted with the vast majority of paints commonly used in construction and decoration, although a compatibility test is recommended beforehand.

Is it suitable for outdoor use and areas exposed to the sun?

Absolutely. Its advanced formulation includes excellent resistance to ultraviolet radiation and adverse weather conditions such as rain, humidity, and temperature fluctuations, guaranteeing that it will not crack or lose color over time.

How should the surface be prepared before application?

To ensure optimal adhesion, the surface must be completely clean, dry, firm, and free of dust, grease, rust, paint residue, or other contaminants. Pre-cleaning with a suitable solvent is recommended if the surface requires it.
