Technonicol mastic for flexible shingles #23 (FIXER)

Technonicol mastic for flexible shingles #23 (FIXER)

Application areas

TECHNONICOL mastic #23 is designed for presizing the seams of flexible shingle and other bitumen materials and for adhesion of bitumen materials to brick, concrete, metal, wood, ceramic and other surfaces.

Description of material

TECHNONICOL mastic #23 is a multicomponent material consisting of bitumen, butadiene-styrene termoplastic elastomer or its modifi cations, filler, solvent and technological additives.

Method of application

Clear the surface of dust, oils, ice-buildup and other contamination. Mastic application on a damp surface is not permitted. When applied to porous bases, the surface should first be prime-coated by using bitumen primer. Wait until the primer is fully dried. Carefully mix mastic before application! Distribute mastic using a putty knife on one of the surfaces in a layer 0.5–1 mm thick. Connect surfaces, avoiding the formation of folds and bubbles. It is recommended that special rollers be used for this. Press surfaces until the appearance of mastic from a seam. Application temperature range — from –5°C up to +40°C. Before using at low temperatures let the mastic stand at room temperature for a period of not less than a day.

Storage

Store in a dry place protected against sunlight at a temperature between –20°C and +30°C. Guaranteed storage period — 12 months.

Ensures reliable bonding

Convenient to use thanks to its packaging
