Tretoshield 6

Tretoshield elastic coating is intended for use in façade and bridge repair work, as well as cracked surfaces treated with, for example, Finish 218.

Summary of properties

• A sufficiently thick coating layer enables bridging of cracks and fractures. 
• Elastomeric properties enable filled-in cracks to move. 
• Prevents water and chemicals from penetrating into concrete elements. 
• Allows water vapour to exit the element. 
• Single-component – easy to use. 
• Excellent adhesion to most construction materials: masonry, brick, concrete, and all Tretoshield cement-based mixes. 
• Fire resistance – meets class 0 requirements according to BS 476 parts 5, 6, and 7. 
• Excellent weather-resistant coating for mineral-based exterior surfaces.

Colour

• Semi-matte, available in white or according to colour chart (BS 4800).
