Neotex® Silimper

Neotex® Silimper is a siloxane-based, penetrating water-repellent treatment for exterior surfaces, designed to protect porous substrates from moisture without altering their appearance.

Suitable Applications

▪ Exterior vertical or inclined surfaces such as concrete, plaster, cement mortars, and brickwork
▪ Natural stone, roof tiles, and joint grouts with continuous surfaces
▪ Façades exposed to rainfall, humidity, and environmental conditions
▪ Restoration and protection of absorbent mineral substrates
▪ Surfaces requiring invisible waterproofing without film formation

Description

Penetrating Water-Repellent Treatment for Long-Term Façade Protection

Neotex® Silimper is a high-performance, siloxane-based water-repellent impregnation designed to protect exterior construction surfaces from moisture penetration while preserving their natural appearance. Unlike surface coatings, it penetrates deeply into porous substrates, forming a hydrophobic barrier within the material structure.

The product significantly reduces water absorption by preventing rainwater from penetrating the surface, thereby protecting substrates from moisture-related damage such as cracking, efflorescence, and surface deterioration.

At Everkast, Neotex® Silimper is recommended for façade protection projects across Nigeria where buildings are exposed to heavy rainfall, humidity, and environmental stress, especially in urban and coastal environments.

Its high penetration capability ensures effective long-term protection without forming a visible film, meaning the original look and texture of the substrate remain unchanged. This makes it particularly suitable for architectural finishes such as stone, brick, and decorative concrete.

The treatment provides early water repellency, allowing surfaces to resist moisture shortly after application, while also improving resistance to dirt accumulation and fungal growth.

Neotex® Silimper is also resistant to alkalis and helps prevent efflorescence, ensuring the long-term aesthetic and structural integrity of treated surfaces. Additionally, it maintains high water vapour permeability, allowing substrates to “breathe” and preventing trapped moisture that could lead to coating failure.

Its excellent UV resistance ensures durability under prolonged sun exposure, making it suitable for Nigeria’s climate conditions.

Being ready-to-use and easy to apply by brush, roller, or spray, it offers a practical solution for both new construction and refurbishment projects.
