What is the required thickness for this type of flooring?

A minimum of 25 mm, typically applied in two layers of 12-13 mm each (Clause 7.2).

What kind of base is required before laying the mastic?

A sound, clean, and dry concrete base or other rigid sub-floor is required. The surface should be primed with a suitable primer (Clause 6).

At what temperature should pitch-mastic be applied?

The material should be laid hot at a temperature between 175°C and 200°C (Clause 7.1).

What are the main components of pitch-mastic as per this code?

A binder (like paving grade bitumen or a mix with coal tar pitch) and inert, graded mineral fillers and aggregates (Clause 4).

Practical Notes

Strict adherence to application temperature (175°C - 200°C) is crucial; overheating can damage the binder and under-heating affects workability and compaction.

The base concrete must be completely dry, clean, and free of laitance to ensure proper adhesion and prevent blistering.

Adequate ventilation is mandatory during application due to the emission of hazardous fumes from the hot mastic.
