Preparation & Application

Preparation

As with all concrete repairs it is essential to remove all grease, oil, dust and other loose materials.

Concrete

Concrete substrates must be adequately prepared either by use of a suitable mechanical method such as scabbling, grit blasting or needle gunning, or by such other means as appropriate. Concrete bases for toppings must be carefully prepared to give a clean freshly exposed sound roughened surface.

Old concrete surfaces contaminated with oil or grease require suitable preparation such as steam cleaning in conjunction with a suitable detergent.

Care must be taken to ensure that the oil or grease is removed from the surface and not simply spread over a larger area.

Steel substrates

Steel substrates should first be grit blasted to BS 7079-A1 equivalent to Swedish Standard Specification SA 2 1/2, followed by degreasing with a suitable solvent (e.g. webertec solvent 3) immediately prior to bonding. However, in many instances where corrosion is absent, wire brushing to a clean bright surface may be adequate, but care must be taken not to just polish the rust on the surface.

Priming

The bond of webertec EP mortar will be improved by the application of a bond coat of webertec bonding aid, both of which are moisture-tolerant primers.

In all cases the webertec EP mortar must be applied whilst the primer coat is still tacky.

When applying webertec EP mortar to vertical surfaces, webertec EP bonding aid should be used as the bond coat.

Mixing

For the large packs, the resin and hardener should first be thoroughly mixed to an even colour and consistency before adding the filler. The quantity of the filler may be adjusted to achieve a less viscous consistency, but should never be less than the amount detailed on the packaging.

The small packs have filler is included in resin and hardner components.

Application

The mortar should be applied using a steel trowel in layers of up to 20 mm thick.

Allow initial set (6 hours approximately) between layers. On vertical surfaces the maximum thickness should be 12 mm.

The mortar should be well tamped to ensure proper consolidation and then trowelled to bring up enough resin binder to thoroughly seal the surface.

Feather edging must be avoided. The edges of all repairs should be "toed in" i.e. cut back so the minimum thickness is not less than 5 mm.

webertec EP mortar can be applied to vertical surfaces as well as horizontal.  Weber has a range of cementitious mortars, which may be more suitable to a particular application.

Cleaning

Uncured material may be removed with webertec solvent 3

Clean all tools etc, with webertec solvent 3 immediately after use.
