Two-component rubber coating RayTech SKY-PLAST-250 (SKY-PLAST-250) for protective and sealing applications

Two-component rubber coating RayTech SKY-PLAST-250 is a solvent-reduced elastomeric system formulated to create flexible, waterproof and abrasion-resistant layers on a variety of substrates. The product forms an elastic film that protects metal, concrete and other construction materials from weathering and corrosion, seals joints and provides a durable barrier against moisture and wear. Designed for industrial, construction and maintenance applications, this coating is applied as a two-part mix that cures to a resilient, rubber-like surface suitable for both protective and sealing functions.

Advantages

SKY-PLAST-250 delivers long-lasting elasticity and good adhesion to common building materials, resulting in reliable sealing performance and mechanical protection. The cured film combines flexibility with resistance to abrasion and water ingress, reducing the need for frequent repairs. Its two-component formulation ensures controlled curing and consistent film properties, while compatibility with standard surface preparation methods makes it practical for professional use.

Suitable for

• Sealing joints and seams in roofs, terraces and balconies
• Protective coating for metal structures and equipment to limit corrosion
• Waterproofing of concrete surfaces, foundations and basements
• Protective overlays for walkways, ramps and areas subject to mechanical wear
• Maintenance sealing in industrial plants and service facilities

Key specifications

• Composition: two-component elastomeric rubber-based coating
• Film properties: flexible, elastic and abrasion-resistant after curing
• Performance: provides waterproofing and protection against mechanical wear
• Application: brush, roller or spray after proper mixing of components
• Curing: room-temperature curing to an elastic, tack-free film (curing time depends on layer thickness and ambient conditions)

How to use

Prepare the surface by removing loose material, rust, oil and contaminants; repair major defects and allow the substrate to dry. Mix the two components thoroughly following the manufacturer's recommended ratio and instructions until a homogeneous mixture is obtained. Apply SKY-PLAST-250 evenly by brush, roller or spray in one or more layers to achieve the required film thickness, allowing sufficient flash-off time between coats. Ensure adequate ventilation during application and allow the coating to cure under recommended ambient conditions before subjecting the surface to service loads.

Usage recommendations

For best results, use appropriate primers on highly porous substrates or on metals with poor adhesion, follow specified mixing ratios precisely, and avoid application at very low temperatures or high humidity. Observe health and safety guidance for handling two-component polymer systems, including use of protective gloves and eye protection and ensuring good ventilation.
