Hack Aid Plast — Polymer Bonding Agent for Plaster on Smooth Concrete | Sunanda (20 kg)

Ask any plasterer who's worked on RCC-framed buildings and they'll tell you the same thing — getting plaster to stick properly on smooth concrete is one of the more frustrating parts of the job. The traditional solution is hacking — taking a chisel or mechanical grinder to the concrete surface to create enough roughness for the plaster to grip. It works, but it takes time, creates damage risk to the substrate, adds labour cost, and on finished or sensitive surfaces, it's simply not an option. Hack Aid Plast from Sunanda Speciality Coatings is the polymer bonding agent that replaces that entire process with a single coat — and does it more reliably than physical hacking ever could.

Applied onto the prepared smooth concrete surface before plastering, Hack Aid Plast chemically bonds to the substrate and creates a textured, adhesion-ready interface that fresh plaster grips permanently. The result is a concrete plaster bonding agent application that eliminates hollow patches, eliminates delamination, and gives the plaster coat the kind of mechanical and chemical key it needs to stay put through thermal movement, moisture cycles, and the long-term stresses that cause bonding failures on smooth surfaces.

It's particularly valuable on RCC columns, beams, soffits, and flat concrete ceiling surfaces — anywhere the concrete is too smooth for direct plaster application and the standard hacking approach either isn't practical or risks damaging the structure. For waterproofing contractors and plastering teams working on construction and renovation projects, Hack Aid Plast removes one of the most common causes of plaster failure from the equation before it ever becomes a problem.

Straightforward brush application, compatible with standard cement-sand plaster mixes, and backed by Sunanda's established construction chemical expertise — Hack Aid Plast is the kind of product that makes a real, visible difference to plastering quality on site without adding complexity to the process.
