Water-Reducing, Plasticising Agent for Cement & Sand Render and Plaster Mixes

Biokil Crown Rendermix is a high-quality plastering additive designed to improve the workability and performance of cement and sand-based render mixes. Acting as both a plasticiser and water-reducing agent, Rendermix produces a smooth, creamy render that is easier to apply, reduces cracking, and enhances adhesion to substrates. Ideal for both internal and external plastering applications.
