Product Description Calcium Chloride Render Accelerator is a technical grade additive (77%-80 purity) designed to dramatically improve the performance of cement based renders. Supplied in a 25kg bag of flakes, this accelerator is ideal for professional use in concrete, mortar, screeds, and rendering applications. When added to your render mix, calcium chloride render accelerator alters the rate of hydration, reducing setting time by up to two thirds for example, from 6 hours to just 2 hours. This makes it especially valuable in cold climates, where traditional mixes may struggle to cure before frost damage occurs. The flakes dissolve quickly in warm water and integrate seamlessly into your mix, improving workability, adhesion, and early strength development without compromising the final finish. Benefits of Calcium Chloride Flakes in Rendering: Accelerated curing, reduces setting time by up to 66% Cold weather performance, enables rendering in winter conditions Improved adhesion, stronger bond to substrates, reducing cracking Enhanced workability, easier to apply and shape Versatile use, suitable for concrete, mortar, screeds, and render Cost efficient, saves time and labour on site Typical Applications of cement render accelerator External wall rendering in cold or damp conditions Cement-based render systems requiring fast curing Projects with tight deadlines or limited working windows Applications near freeze-prone environments Enhancing adhesion on aged or porous surfaces Calcium Chloride Render Accelerator is designed to enhance the performance of cement based renders. Supplied in flake form, it is easy to dissolve and mix, making it a preferred choice for professionals working in cooler climates or on time-sensitive projects In addition to speeding up curing, calcium chloride improves early strength development, which helps reduce shrinkage and cracking. It also enhances adhesion to substrates, making it ideal for rendering over older or porous surfaces. The improved workability makes the mix easier to apply and finish, especially in vertical or overhead applications.
