Best Uses

Axalta Corroless ACO Mastic Rapid Grade is suitable for the use of coating of field joints, repair of damaged coatings, filling of holes and cracks, on steel pipelines and other steel structures. This Rapid grade is specifically developed for use at lower ambient temperatures. For temperatures above 25°C the Mastic Standard Grade should be used, as this Rapid grade will be too fast curing.


All surfaces to be coated should be dry and cleaned as necessary to remove all oil, grease, salts, weld flux or other contamination. Where necessary, remove weld spatter and grind smooth all sharp edges and weld seams.

Steel: blast clean to minimum Sa2½ (ISO 8501-1:2007), surface profile depth 75-100μm. Mechanical tools may also be used, providing a profile of minimum 75μm. Do not polish the steel surface

Overlap onto existing pipeline coating: remove any loose material to establish a firm edge. Feather sound coating and abrade surface to provide a key. Thoroughly abrade to remove gloss, surface contaminants etc. by suitable method (sweep blasting, abrasive disking etc.)

Concrete: remove all laitance and other contaminants by most appropriate methods. Ensure the concrete is dry to a reading of <16% on the Wood Moisture Equivalent (WME) scale. Prime with Corroless ACO LV Sealer.

Designed for application by brush, roller, putty knife, trowel or spatula.
