Sikadur®-915

(former MSeal 915)

High strength, free-flowing epoxy grout

The product is three component and easily mixed on site to a pourable consistency. Sikadur®-915 is suitable for an application thickness range of 10-80mm where high flow characteristics are required. Where greater thicknesses are required, pour in two sections leaving 6 hours between each pour or consider the use of SikaFlow®-640.

Product Details

Product Information

Composition

Bisphenol A epoxy resin base is a low viscosity liquid reactor which when mixed with the inert aggregate forms an easily pourable and mobile grout.

Up to 12 months when stored in unopened containers according to manufacturer’s instructions.

Storage conditions

Store under cover, out of direct sunlight and protect from extremes of temperature. In tropical climates, the product must be stored in an air-conditioned
environment. Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging.

Application steps

SUBSTRATE PREPARATION

As with all epoxy resin applications, the quality of surface preparation has a direct effect on the performance and durability of the system. Concrete surfaces should be sound, dimensionally stable, clean, free from laitance, paint, oil, grease, mould release agent and residual curing compound. Metal surfaces or components to be bedded should be free from any rust or scaling. Formwork, if used, should be wrapped in polythene to ensure a clean release.

 

MIXING

Do not split packs or alter the ratio of resin components in any way. Mix with a slow speed drill and paddle. Add the contents of the reactor container to the base component in a suitable mixing vessel, ensuring complete transfer of both resin components.
Mix for one minute before slowly adding the aggregate and continue mixing until a flowing, pourable consistency is achieved. Do not over-mix, as that may entrain air.

APPLICATION

Place immediately after mixing, into the prepared area in such a manner that it has the shortest distance to flow. For longer pours, a suitable head of pressure may be required. Ensure the area to be grouted is not completely sealed, and any displaced air can be expelled. Pour continuously from one end only. Allow the grout to set prior to removal of formwork (normally after 6 hours). Where placement exceeds depths of 80mm, application should be carried out in layers. The second layer is to be applied after 6 hours.

CLEANING OF EQUIPMENT

Clean all equipment promptly with solvent. Any excess cured material will have to be mechanically removed.
