ExoSET™ - Calcium Chloride Render Accelerator - 6kg tub

Technical-grade Calcium Chloride 77% render accelerator

Calcium chloride is used as an admixture for use in concrete, mortar, rendering or screeds 

ExoSET™ changes the rate of hydration and accelerates the time needed for render to 'go off' or 'cure' and reduces the settlement of concrete. 

Concrete is damaged if it does not reach a strength of 500 pounds per square inch (3.4 MPa) before freezing. 

Using Calcium Chloride accelerator allows concrete to be placed in winter with reduced risk of frost damage. 

Render Accelerator Ratio

A rate of 2% is often quoted within the industry - although this varies between anhydrate and dihydrate, the ExoSet Render Accelerator is dihydrate so 2% by weight of cement*1.

You should satisfy yourself as to the concentration and ratios required, bearing in mind protection against future corrosion when in contact with metals.


In the usual 1 to 2 percent range it typically reduces the water needed for a given slump only about 1 percent - no discernible difference.*1

Setting time

The 2% range has been calculated to reduce setting time by 2/3. Example, a setting time would we reduced from 3 hours to 1 hour, or 6 hours to 2 hours.*1
