Bonding

Introduction

Gyproc BOND-it is a bonding agent that enables quick preparation of ceiling and wall surfaces (especially RCC surfaces) within 24 hours. It enables dual benefits of mechanical and chemical bonding, which eliminates the labour-intensive hacking process and the risk of plaster de-bonding.

Features

  • Dual bonding (mechanical as well as chemical grip)
  • The green colour makes identification easy
  • Application in one coat
  • Contains fine aggregates for better mechanical, as well as chemical adhesion
  • Works equally well for both gypsum and sand-cement plaster
  • Its Mandatory to apply on any low-suction surface (concrete surfaces like RCC columns, beams, slabs, shear walls)

Benefits

  • Eliminates the risk of de-bonding
  • Twenty times faster than traditional hacking
  • Easy single coat application
  • No tackiness requirement for bonding (after drying in 24 hours, Plaster can be applied over it upto 10 days)

Application Procedure:

Background Preparation:

Surface on which BOND-it application to be done should be clean, dry and free from mold oil or any other agents. Any faults in the structure, particularly those which may lead to moisture penetration, must be rectified. Just before application of BOND-it, prewetting must be done with the help of a brush/roller.


Mixing

Mix material properly with clean rod to properly distribute solid particles in the solution.


Application

Use good quality paint brush. The brush should be cleaned with enough water immediately after use. Apply with even distribution of fine aggregates over the surface. Allow it to dry thoroughly for around 24 hours.

FAQs

I am not getting coverage of 5 sq-m/kg with BOND-it. What should I do?

One of the main reasons of not getting the desired coverage is over application of BOND-it on the surface. The material should be applied in a single coat after proper stirring of the content in the bucket. Also pre-wet the surface to enhance coverage.

Can BOND-it be mixed with water and applied?

No. BOND-it should not be mixed with water as it decreases the strength between plaster and the substrate. However it is advised to spray some water on the surface before application to remove dust particles and to also increase the workability of BOND-it on RCC surface

Why Gyproc BOND-it is a must on RCC surface?

With increase in hardness of the RCC alongwith with more construction sites moving towards aluminum formwork shuttering and more number of high rise buildings coming up, the process of hacking has become difficult. Also the low suction background of these surfaces doesn’t give proper bonding with the plaster surface. BOND-it provides chemical bonding as well as mechanical key to the applied plaster giving it the desired strength

What is difference between hacking and Gyproc BOND-it ?

Hacking is the process of roughening the RCC surface to hold the plaster. Since hacking is done manually, it is not consistent, which means there is the risk of plaster debonding.

Gyproc BOND it is a ready-to-apply liquid chemical, containing coarse aggregates that give the mechanical key and chemical bonding to plaster, thereby eliminating the risk of de-bonding.

  • Surface preparation through BOND it as a bonding agent
  • Gyproc Elite 90 as a single coat levelling plaster
  • Gyproc Champion Putty as a smoothing putty to make the surface paint-ready
