How to apply Screed X C25

Hack and roughen the concrete surface using wire brushes for a better bonding.
Clean the surface thoroughly to remove dust, dirt, and loose particles.
Mark the finished floor level clearly at multiple points.
Wash the surface with water, but do not let the surface dry before screed application.
Open the Screed X bag and mix it with the recommended water to get a smooth consistency.
Mixing shall be done thoroughly until a homogeneous, lump-free mix is achieved.
Do not mix with other products or materials.
Spread the screed uniformly up to the finished floor level.
Maintain a screed thickness of 10–40 mm, with a minimum of 10 mm under tiles.
Over this mortar bedding, Apply neat grey cement slurry (honey-like consistency) at 3.3 kg/m² over an area of up to 1 m².
The tiles shall be laid on the bedding mortar while it is still plastic, but has become sufficiently stiff to offer a fairly firm cushion for the tiles.
Apply a suitable primer(optional) before screed application to enhance bonding between the screed and substrate.
Curing should be done minimum for 3 days.
