How to bond plaster to new concrete or RCC?
We shall first understand the old methods of bonding plaster to new concrete and their disadvantages. Later, we shall reveal the latest and most cost-effective method of bonding plaster to the new RCC.
Before plastering, the concrete slabs (soffits or ceilings), walls, columns, and beams are hacked with a chisel and hammer to coarsen their surfaces for the plaster to interface with the concrete surface.
Due to this, you cannot sustain conformity and stability in the number of hacks per sq. ft, which is left to the acumen of the construction applicator on site.
Due to the above reasons, hacking is not carried out nowadays.
After hacking, then came the use of PVA for plastering. The method above has drawbacks; the PVA has drawbacks, and the PVA agents are not water-resistant and have a limited shelf life.
The ideal way to bond plaster to new concrete is the application of bonding agents. Plaster bonding agents are a new-age invention that eliminates hacking and increases bonding strength after curing concrete.
Sunanda Global’s bonding agent for plaster has non-ionic properties; therefore, there is zero possibility of chemical ion (chlorides, alkali sulfates) attacks on concrete. Due to this property, the RCC steel does not deteriorate and protects the bond between steel and concrete.
Carry out the procedure in the following manner below:
- Clean the concrete surface thoroughly to remove dust, dirt, grime, and deshuttering oils, followed by washing with a water jet.
- Apply Hack Aid Plast by spraying/brushing on the entire concrete surface.
- Wait till the polymer gets tacky.
- The tacky period may vary depending on external weather conditions, temperature, saturation degree of the substrate, etc.
- When the surface becomes tacky, apply a chat-dash of cement mortar coat (1:4 ratio) within 10 minutes.
- Allow the dash coat to set for around 24 hours.
- Plaster the surface or place the concrete as usual after setting the chat/dash coat.
