SURFACE PREPARATION
Concrete
All surfaces should be clean, dry and free from curing compounds, release agents, troweling compounds, standing water, grease, oil, dirt, bitumen coatings and loose or disintegrating concrete. All poured and precast concrete must also have blasted, wire brushed or acid etched to remove laitance.
Surface preparation shall not take place in following conditions:
- At temperature below 5 ºC.
- When the surface temperature is less than 3 ºC above the dew point.
APPLICATION
Material is supplied in two containers as a unit. Always mix a complete unit in the proportion supplied. Once the unit has been mixed it must be used within the working Pot life specified.
1-Agitate Part A and B separately with a power agitator.
2-Combine entire contents of curing agent (part B) with base (part A) and mix thoroughly with power agitator.
3-Mix thoroughly for at least three minutes, scraping the container bottom and side to assure complete mixing. There is no induction or waiting time required after mixing before application.
ABAZONE-290 coating can be applied using good quality rollers or short haired brushes or by airless spray. It is recommended that ABAZONE-290 coating be applied in two coats to ensure complete coverage. Prior to the application of each coat the surface should be examined for signs of pin-holing, etc. Where pin-holing is evident these should be filled using ABADUR MP repair system.
If the over-coating is delayed more than the drying time table, the previous coat must be thoroughly abraded to give an adequate mechanical key and solvent wiped. In hot climate, material temperature should be 20 to 25 ºC prior to mixing; otherwise pot life becomes very short. Do not thin for any reason.
