International Intergard 740

International Intergard 740 is a tough two component epoxy finish coat suitable for concrete that offers good abrasion and chemical resistance in corrosive environments.

Best Uses

International Intergard 740 is formulated as a tough, hard wearing finish for application over properly primed surfaces. Exhibits good abrasion resistance, and affords good protection against spills and splashes of a range of chemicals such as acids, alkalis, solvents, and salt solutions. Suitable for use in a wide range of environments including offshore structures, petrochemical facilities, bridges, pulp and paper mills, and the power industry. This product is ideal for offshore wind farms.

Application

All surfaces to be coated should be clean, dry and free from contamination. Prior to paint application all surfaces should be assessed and treated in accordance with ISO 8504:2000.

Primed Surfaces
Intergard 740 should always be applied over a recommended anti-corrosive coating scheme. The primer surface should be dry and free from all contamination and Intergard 740 must be applied within the overcoating intervals specified (consult the relevant product data sheet). Areas of breakdown, damage etc., should be prepared to the specified standard (e.g. Sa2½ (ISO 8501-1:2007) or SSPC-SP6, Abrasive Blasting, or SSPC-SP11, Power Tool Cleaning) and patch primed prior to the application of Intergard 740.

Concrete, Pre-Cast Blockwork etc.
Intergard 740 is suitable for application to concrete. For the first coat it is recommended that Intergard 740 is thinned 10-15% by International Thinners in order to provide good penetration of the concrete substrate and act as a primer / sealer coat. Concrete should be cured for a minimum of 28 days prior to coating. The moisture content of the concrete should be below 6%. All surfaces should be clean, dry and free from curing compounds, release agents, trowelling compounds, surface hardeners, efflorescence, grease, oil, dirt, old coatings and loose or disintegrating concrete. All poured and precast concrete must also be sweep blasted (preferred) or acid etched to remove laitence.

Plaster, Cement Render, Concrete etc.
The surface should be clean, dry and free from contamination. Remove old, loose or flaking paint. Fill and sand minor defects. Damp patches, oil staining, bitumen bleed, nicotine deposits, efflorescence and rust discolouration must either be treated at source, or better, the cause of such stains/defects removed. Existing mould, algae and other growth must be killed before commencing work. Domestic strength bleach diluted 1:4 with water or a proprietary fungicide solution should be used. Two treatments may be necessary, after which the area must be washed down and scrubbed to remove residues. Ideally, to prevent future infestations the conditions which support growth should be identified and cure sought.
