Any residual surface water should be removed prior to commencement. Care should be taken and the work scheduled to ensure the water does not run onto areas of recently applied Matex PRCH less than 12 hours old. Under severe drying conditions repeated soaking may be necessary to ensure the substrate is still saturated at the time of application.

MIXING:

Use 6 to 7 ltrs of water for every 25 kg bag depending on consistency required. Mix using a slow speed heavy duty drill machine fitted with a paddle. Mix for approximately 3 minutes till a uniform mixed consistency is obtained. Part mixing can be adopted provided correct water to powder ratio is maintained.

Applications Thickness is 1 mm up to 5 mm can be applied in one layer.
