What is it?
Leocatic Spray is a 60% Bitumen content, cold applied cationic emulsion. Leocatic Spray is particularly useful for the construction and maintenance of footways and other low stress sites.
Where to use?
- Surface dressing
- Stabilising footpaths
- Bond coats
Leocatic Spray is ideal for surface dressing lightly trafficked sites such as footways. Depending on site conditions it may be necessary to apply a double surface dressing wherein two binder and chipping applications are carried out in quick succession.
On sites subject to low stress it may be economical to prepare, in situ, a combined binder/surface course by means of an application of Leocatic Spray into the interstices of the aggregate after the latter has been spread on the foundation and compacted. Leocatic Spray is particularly effective where the stone layer is open or wet.
When repairing potholes and deep depressions, the area to be treated should first be cleaned of all loose material and cut out to a regular shape with all the sides vertical or slightly undercut. The bottom and sides of the hole or depression should be thoroughly coated with emulsion. Clean aggregate should be placed in the hole to a thickness slightly greater than its depth and well rammed or rolled. The minimum amount of emulsion required to coat the stones should then be poured on (excessive amounts of emulsion may create 'fat' spots in the road). The patch should then be covered with clean 10mm or 6mm chippings and again rolled or rammed.
Protect from frost. Drums should be rolled frequently to avoid separation. For further information please refer to BS434: Part 2: 2006 Section 5; Clause 5.2 storage
