Leotak
Leotak is a cold applied rapid-acting 40% cationic bitumen emulsion. When cured Leotak forms a thin uniform film of bitumen on the road surface which gives an adhesive bond between a bituminous overlay and an existing surface.

For best results, tack coating is strongly recommended when performing such tasks as overlaying with hot rolled asphalt, macadam or when patching or carrying out inlaid work.
Leotak adheres exceptionally well, even in damp conditions. The overlay is held securely in place and the entry of water between road pavement courses is hindered.
- Carriageways
- Footways
- Car parks
Surface to be treated must be free from detritus, standing water, loose materials and oil spillage.
Leotak should be sprayed or hand applied between 0.3-0.6 l/m2 (depending on the texture, porosity etc. of the surface) to give the thinnest film consistent with complete coverage.
Vehicular traffic should be kept off the treated area until the emulsion has fully broken, colour changes from brown to black. When emulsion has fully broken then apply the overlay.
1 x 25kg container should cover approximately 40m2
1 x 200kg drum should cover approximately 320m2
Leotak is available in bulk, 200kg drums, 25kg and 12.5kg containers.
Protect from frost. Bulk material should be circulated before use. Drums should be rolled frequently to avoid separation. For further information please refer to BS434-2 2006 Clause 5.2 Storage.
Leotak is a CE Marked cationic emulsion to BS EN13808:2013 C40B.
