Preparation
The key to any successful installation is the preparation .
Because we are using polyurethane screed we prefer to scabble the floor removing any old coatings and producing a good keyed surface.
The photo on the right shows a wall chasing machine fitted with two diamond blades putting an anchorage groove around the room perimeter.
This groove is also placed around channels or fixed objects and either side of any expansion joints .
The reason for this groove is to achieve maximum bond between material and floor .
All grooves are cleaned out using a hammer and bolster chisel to produce straight edges .
This room required the fall to be increased and after taking level readings we achieved this using polyurethane infill screed.
