dryseal

Dryseal is a brand of waterproof sealant primarily used for protecting porous building materials. It is a silicone-based emulsion that penetrates the surface of materials such as stone, brick, concrete, and render, creating a water-repellent barrier. This barrier prevents water ingress without significantly altering the appearance or breathability of the treated surface.

The application of Dryseal typically involves spraying or brushing the liquid onto a clean, dry surface. Once dry, it forms a hydrophobic layer that repels water, reducing issues like dampness, efflorescence, and freeze-thaw damage. It is commonly used on exterior walls, patios, and other structures exposed to the elements. The product is designed to be long-lasting and maintain its effectiveness over several years, though reapplication may be necessary depending on environmental conditions and wear. Dryseal is not intended to be a structural sealant or to bridge large cracks. Its primary function is to prevent liquid water from entering the pores of the material.
