HPMC vs MHEC vs HEC: Which Cellulose Ether for Which Mortar? HPMC, MHEC and HEC are all cellulose ethers, but they are not interchangeable. HPMC holds water best and suits most cement mortar; MHEC gels higher and wins in hot weather; HEC holds water poorly and belongs in paint and stone paint. This guide compares gel temperature, water retention and cost so you pick the right one.

RDP Chemistry Explained: VAE vs VeoVa vs Acrylic vs SBR — Which Polymer for Your Mortar? Which RDP polymer suits your mortar? VAE is the cost-effective workhorse; VeoVa resists water and alkali for coastal facades; acrylic gives best UV and color stability; SBR suits interiors only. Dosage trades strength for flexibility: S1 needs ~40 kg/t, S2 ~100 kg/t. CHARING offers VAE grades and VAE-acrylic terpolymers for waterproofing.
