Description

BASE ONLY, VISIT HERE FOR LIQUIDS. VISIT HERE FOR KITS.

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. 

 

You have a working time of approximately 20 minutes, depending on size and complexity, the cast should be left in the mould for a further 2½ – 3½ hours and achieves over 90% of its ultimate strength in the first 24 hours.

500kg and 1000kg Bulk Bags of Jesmonite AC730 Base are available on for all stone finishes - please enquire for prices and availability.

Storage 

As a basic rule Jesmonite 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 twelve months. Freezing must be avoided. Powders should be kept dry and stored at 5-25oC.
