POLY-HACK is a specially developed single pack polymer emulsion interface for strengthening bond between plaster and concrete (new as well as old). It can also be used for installation of ceramic or glazed tiles on concrete. As a special application it can also be used to coat reinforcement steel.

 

Its unique features are as follows:

 

• Tremendously improves the Plaster – Concrete bond
• Bond strength improves with curing of plaster
• Neutral product having porosity less than 3 microns. Hence greatly protects concrete from carbonation and attacks of salts
• Forms a breathable coat i.e. allows the moisture from concrete to escape but does not allow external water to penetrate concrete
• Has excellent bonding with steel, thus protects it from corrosion and also improves bonding between concrete and steel
• Improves speed of plastering & guniting due to reduction in rebound losses

 

Method of application:

 

• Clean the concrete surface in order to remove any grease, oil, dirt & loose particles
• Make the surface damp by moistening with water
• Spray 1 uniform coat of POLY-HACK on the moistened surface and ensure that the surface is coated evenly and fully
• The surface starts becoming tacky in 10 to 20 minutes.
  
• After the surface develops a proper tack, then apply chat coat of cement–mortar
• Allow the chat coat to settle and start plastering in the regular manner

Coverage: Approximately 100 ft² / litre of POLY-HACK on a relatively smooth surface.

 

Packing: Available in 1, 2, 5, 20, 35, 50 & 220 kg packs.

 

Shelf life: The shelf life is 1 year when stored in original pack in cool and dry place.
