Jesmonite AC730 is a rapid setting acrylic polymer modified cementitious composite. It is a shrinkage-compensated material of low permeability and is durable in all conditions of external weathering. The compound is alkali free and as such is free from the efflorescence associated with Ordinary Portland Cement based systems. The product contains a fine decorative aggregate and powder pigments, carefully controlled to give a consistent decorative surface finish after treatment with a proprietary brick cleaner or acid etch. It is supplied as two components, a water-based acrylic liquid, and a blended powder.

It can also be used to create Garden ornaments and statuary, and is suitable for water-features.

 

Key Attributes

 

Improved flexural strength and stability

Excellent Abrasion resistance and impact strength

High Compressive and tensile strength

Shrinkage compensated and dimensionally stable

 

Storage

 

As a basic rule liquid containers should be kept well sealed to prevent water evaporation and skin forming. They should be stored at a constant temperature between 5-25oC and used within six months. Freezing must be avoided. Powders should be kept dry and stored at 5-25oC.
