Castlebond Epoxy Bonding Compound is a tough, flexible clear epoxy resin that may be used with any commercially available aggregate or filler to produce an economical hardwearing composite with many uses. It can be mixed with coloured sands or graded aggregates at low ratio to make tough, durable drives, pathways & parking areas. Castlebond can also be mixed with sawdust to produce an intensely hard wood filler or with metal dust to make a repair filler for castings, etc.

+ = Resistant 0 = Not resistant

All chemical resistance measured at 25°C

All surfaces to which Castlebond is to be applied should ideally be clean, dry and free from dust and loose particles. Acceptable adhesion can be achieved on damp surfaces (up to 50% RH). Fillers need not be dry but best results are obtained with clean, dust-free materials, e.g. washed aggregate, washed sand, etc.

Prepare Castlebond by mixing 2 parts of Base with 1 Part of Hardener and stir well for 2/3 minutes (7.5 litre packs are pre-measure). Do not mix more than can be used in 30 minutes.

AGGREGATE SCREEDS: Castlebond screeds may be laid over any firm, level surface such as old concrete, stone, brick or tarmacadam areas. Well-consolidated earth may be sufficiently firm but a layer of sub-base or 'hoggin', mechanically compacted will ensure that no sinkage develops at a later date. After pre-mixing Castlebond resin as above; mix in the chosen aggregate or sand at the appropriate ratio. Up to 20 litres can be dispersed with a spiral mixer fitted to a slow-speed drill. Larger mixes such as drive and car park applications are best carried out with a power mixer such as a 'Crete-angle' or 'Mixall' mixer. Gravity cement mixers are not suitable. Mix until all aggregate is completely coated with resin or with sand mixes until the sand is evenly wetted. Spread immediately and float, trowel or tamp to a level surface. Water & Teepol may be used to prevent mix sticking to tools. For drives & car parks, a minimum thickness of 20mm composite at a ratio of 10:1 aggregate to Castlebond is recommended. For lighter applications e.g. paths, 10 thick composites at ratios of 15:1 or 20:1 can be used.

Clean equipment with acetone or MEK before the material has cured.

The colour of the aggregate or filler will determine the colour of the finished composite. Aggregates are available in various shades and mixed colours can achieve a pleasant effect on drives and pathways.

NOTE: Aggregates are sold by weight. For estimating purposes allow an average bulk density of 1.6 Kg/Litre, i.e. 1 x 40 Kg bag of aggregate equals approximately 25 litres.

This data is provided in good faith for guidance purposes, however due to variations in equipment and local conditions, users should carry out their own tests to ensure that satisfactory results can be obtained.
