Wall/Floor Primer Peeling? Fix the HPMC/RDP Ratio
Wall and floor primers have a core job: penetrate, seal, and reinforce the substrate. They must provide a solid base for the layers that follow. Yet peeling and chalking are common complaints. A light scratch leaves a white mark, and
Keying Strength Low? HPMC for Workability, RDP for Bond
The core function of a concrete bonding agent is to create a rough "key" between the old substrate and the following plaster or repair layer. This increases contact area and mechanical interlock. In practice, however, low keying strength is a
Bonding Old & New Concrete: HPMC Wetting + RDP Film
The interface between old and new concrete is the weakest link in any repair project. Peeling, hollow spots, and cracking almost always start from bond failure at this interface. To solve the problem, we must look beyond the strength of
Thin Repair Mortar: Balancing HPMC Dosage & RDP Tg
Thin repair mortar is typically applied at a thickness of just 3 to 10 millimeters. This narrow range imposes extreme demands. It must bond firmly to the old substrate to prevent debonding, yet stay flexible enough to absorb shrinkage stress
2-Hour Repair Mortar: HPMC + RDP Synergy
Road repairs and runway patches demand one thing above all: speed. Traffic must often resume within two hours. That requires extremely fast early strength development and strong bonding. The key isn’t a single material. It’s the efficient synergy between HPMC
SCC Air Content Too High? Fixing Cellulose Ether Air Entrainment
Self-compacting concrete needs high fluidity, excellent filling ability, and resistance to segregation. Cellulose ethers play a key role in achieving that stability. But there's a downside. The wrong cellulose ether — or poor process control — can push the air
