Colours
Note: In order to limit minor colour variations from batch to batch, it is advisable to use product from the same batch on large
open areas. Batches may be factory blended on request.

Surface Preparation
Concrete surfaces must be clean and mechanically sound and free of laitance, nibs, dust, grease and oil. Wet abrasive grinding is generally used on concrete floors, the final prepared surface must provide an open textured finish typically like 80 grit sand paper. Any holes should be filled with an adequate mortar, e.g. sand/cement gauged with duralatex and laid into a duralatex/cement/sand slush. Surfaces do not need to be dry as long as they are free of standing water. Bone dry surfaces must in fact be lightly dampened with water to prevent too rapid suction of water from the coating.
The surface must provide a minimum of 25 MPa compressive strength and 1.5 MPa tensile adhesion strength.
Pot Life
Mixed abecote® 337 has a pot life of some 90 minutes at 20 ºC. While unused material may still appear workable after this time, it must under no circumstances be used.
Coverage
8 – 10 m²/L/coat on smooth surface. Minimum recommended number of coats: prime coat plus 3 top coats.
Application
Mixed abecote® 337 may be applied to the dampened substrate by water pre-moistened brush or roller or by airless spray using a ±500 µm tip. Ideally any first coat should be applied by brush. As soon as a coat is touch dry, a subsequent coat may be applied. Unless the treatment is required to provide chemical resistance, an additional two coats are normally sufficient. Chemical resistant work or floors always requires three coats. Drying time will depend upon temperature, humidity and ventilation. If working indoors or in confined spaces, ensure adequate ventilation. Outdoors, the wet film is liable to wash off in rain or be damaged by frost.
abecote® 337 may be over coated at any time. Ensure that the surface is clean and free of contamination and chalking. Over coating, without intercoat adhesion problems, may be carried out with abecote® 337 itself or solvent-borne or solvent-free epoxies or other compatible coatings.
USE AS A CONCRETE MEMBRANE
abecote® 337 can be applied to green concrete as a curing membrane, after which it becomes a protective and decorative coating. In this application it acts as protection during subsequent construction, this also applies to floors. When final decoration and protection of the surface is due for application, the surface need only be suitably cleaned and repaired to take whatever final treatment may be specified. Consult a.b.e.®’s Technical Division for advice.
Cleaning
During brief interruptions of work, equipment should be immersed in clean water. At major stoppages it must be washed with soap and water or with abe®super brush cleaner. Cured abecote® 337 is almost impossible to remove.
Protection on Completion
Protect against traffic and spillage until cured. Most epoxies chalk and degrade in extensive sunlight.

Handling & Storage
All abecote® 337 related products have a shelf life of 24 months if kept in a dry, cool store in the original, unopened packs. If stored at high temperatures and/or high humidity conditions, the shelf life may be reduced.
Bonding / Priming
On porous surfaces dilute abecote® 337 as the primer coat with up to 10 – 15% clean water and pre-dampen the surface to obviate suction.
Mixing
Pre-stir base and activator. Add the entire base to the activator and stir for at least 5 minutes using a flat paddle. It has been found that mechanical mixing gives better dispersion than manual mixing. A suitable mixing method would be a slow-speed electric drill (approximately 200 r/min) fitted with a paddle.
