DESCRIPTION
Perma Floor Top is a floor hardening compound based on non-oxidising metallic or non metallic aggregates a blend of ordinary portland cements and activating chemicals. Perma Floor Top is for use on green concrete of industrial floors to achieve high abrasion and impact resistance properties on the finished floors.
Depending upon the selection of aggregates Perma Floor Top is available in 2 grades:
1. Perma Floor Top AI : Based on non-oxidising metallic aggregates.
2. Perma Floor Top QZ : Based on non-metallic aggregates.
PERMA FLOOR TOP AI
A special grade of product based on aluminum oxide aggregates which makes the floor exceptionally hard durable and abrasion resistant. Floors treated with PFT-AI are resistant to oil and grease spillages and tend to be non slippery. Further these floors are resistant to spillages of acids and alkalis. These floors with stand constant spillages of water. Perma Floor Top AI treated floors are ideally suited for, engineering workshops, warehouses, abattoirs, service station etc.
PERMA FLOOR TOP QZ
Perma Floor Top QZ is based on non-metallic quartz aggregates. Perma Floor TOP QZ treated floors are ideal for places where chemical spillages are expected, and where metallic aggregates are not desired. Perma Floor Top QZ is used in concreting of floors for laboratories, chemical factories, breweries, shopping centres, super markets etc.
PRIMARY USES
Perma Floor Top products are designed for high abrasion and impact resistance properties to the concrete floors.
DIRECTIONS FOR USE
After floor concreting when the concrete is firm to take the weight of workman sprinkle Perma Floor Top at the desired rate on the green concrete and trowel it in with metal floats or power trowel. Care should be taken to see that concrete surface is just ready to receive dry shake powder. If delayed too much it will become unworkable and if Floor Top is sprinkled too early it will get mixed with the concrete and loose its utility. Sprinkling of Floor Top should be controlled such that an uniform quantity of the product is sprinkled through out. It may be suggested that broadcasting of Floor Top be done in two stages. The second stage of broadcasting done in a perpendicular direction to the first stage broad cast.
CURING
Curing should be carried out immediately after final trowelling has been completed.

PRECAUTIONS
Floor being a very important utility member of any industrial or commercial unit sufficient care needs to be taken while designing and execution. The following precautions however need to be taken while concreting a floor.
BASE CONCRETING
The base concrete should be well designed incorporating atleast 350 kgs of cement per cubic metre of concrete and water cement ratio to be kept at a minimum to produce low slump concrete. Floor concrete needs to be well vibrated and power floated.
STRESS RELIEF JOINTS
While concreting in bay the size of the bay should be ideally 3m x 4m for 100 mm thick concrete. Concreting bay sizes can be increased with thickness of concrete increasing.
Every 12 meters a crack inducer joint and every 36 metres an expansion joint needs to be introduced. If long bay pattern of concreting is used as in case while using vacuum dewatering machine relief joints should be cut every 10 metres using a concrete saw. This joint is normaly 6 to 10 mm wide and about 40 mm deep. This relief joint should be cut after 24 hours of concreting but before 72 hours. In this method also expansion joint becomes necessary every 36 metres in either direction.
