Description
CONCRESIVE 1418 is a two-component polyester resin compound consisting of a liquid resin and a powdered hardener filler system in one container. It is a repair, bonding and grouting material.
Primary uses
- Repair of pre-cast concrete units
- Repair of worn or damaged concrete.
- Bedding and sealing concrete units, steelwork, road furniture, etc.
- Fixing tiles, slabs, pre-cast facings, etc.
- Grouting in dowel pins, rag bolts, holding down bolts and starter bars.
Advantages
- Easy to use - economical and fast.
- Simple to batch and mix.
- Versatile - has many applications.
- Mix consistency can be varied at will.
- Excellent adhesion to most building materials (ceramics, wood, metal, stone, concrete, quarry tiles, asphalt, mortar, etc.).
- Excellent chemical resistance.
- High early and ultimate strengths.
- Due to the nature of the resin system, the mechanical and chemical resistance of CONCRESIVE 1418 is constant irrespective of the volume of filler added provided adequate compaction can be achieved.
- CONCRESIVE 1418 has low shrinkage properties and does not shrink at the bonded surface. No shrinkage occurs once hardening has taken place.
- Will cure underwater and at temperatures below 0°C.
- Extra sand can be added for bulk filling.
Packaging
CONCRESIVE 1418 is supplied in 15kg containers. Each container contains resin and adequate powder for normal use.
Action
The action of mixing the powder and liquid components of CONCRESIVE 1418 results in a chemical reaction producing a material of exceptional strength and chemical resistance.

Application procedures
Surface preparation:
Ensure surfaces are free from oil, grease paint, curing compound, etc. remove dust laitance and friable materials by wire brushing, bush hammering or acid etching. It is preferable to abrade and roughen smooth surfaces prior to application of CONCRESIVE 1418.
Mixing:
Mixes normally used vary from 2:1 powder to resin up to 4:1 powder to resin by volume. The resin rich mixes are flowable and the leaner mixes are trowellable. Mixes as lean as 5:1 can be used as space fillers but these will not necessarily develop the full properties.
Pour required quantity of resin into a clean plastic bucket and add powder filler stirring continuously until desired consistency is reached and the mixture is smooth, lump free and uniform in colour.
Do not mix more material than can be used within 20 minutes.
Application:
CONCRESIVE 1418 should not be applied in coats thicker than 20mm. Where repairs are to be above 20mm, it is preferable to apply CONCRESIVE 1418 in layers each with a maximum thickness of 20mm. Apply successive coats after the previous coats have hardened.
When using material of flowable consistency, ensure material is given time to settle and self-level before proceeding. When using material of trowellable consistency work it well into the surface to be prepared. Build up layers ensuring good contact and adhesion between coats. Finishing is best effected by applying a little hydrocarbon solvent, to the trowel. Use clean smooth tools.
Coat thickness depends on location and substrate. A general guide is up to 20mm on horizontal applications, 12mm on vertical applications and 4-6mm per coat on soffits.
