UsageQuickmast 341 adheres well to most building materials without the need for a primer, as well as exhibiting very good abrasion and chemical resistance along with negligible shrinkage. Quickmast 341 applications include: Patching repair to defective concrete. Bonding: concrete to concrete, steel to concrete, rubber to concrete, natural stone (such as granite, limestone and marble) to concrete , natural stone (such as granite, limestone and marble) to steel. For gap filling and pin holes in concrete For bonding all types of tiles As a base coat for epoxy and polyurethane coating. Materials SuppliedQuickmast 341 is available in 1 and 5 kg packs Coverage
1 kg Pack (0.67 l).
Storage/ Shelf LifeProtect from frost and
store under dry warehouse conditions at temperatures between 5°C and 30°C. Quickmast 341 has a shelf life of 12 months from date of manufacture if stored in unopened, undamaged, sealed containers and stored under good conditions. RemarksQuickmast 341 has a working
time between 60 - 90 minutes at 25°C. Mixed material should not be left
standing for any length of time prior to application, as this will considerably
reduce its working time. Quickmast 341 should not be applied at temperatures below 5°C. When
exposed to temperatures over 35 °C it will have a shorter pot and
working life. Quickmast
341 should never be applied in direct sunlight. |
Technical Information
Application InformationSUBSTRATE PREPARATION
The
surface must be structurally sound, free from oil, grease and other forms of
contamination. Concrete surface should be dry and suitably prepared either by
scabbling or grit blasting to remove any surface laitance. Steel
surfaces should be grit blasted to remove all rust and scale (see the DCP Guide
to Surface Preparation for further details). The
effectiveness of decontamination should be evaluated using a pull-off test. Quickmast 341 comprises two components, a resin base and a hardener, which are supplied preweighed in the correct proportions. Under no circumstances should part mixing be carried out. When required for application, the two components should be mixed well until a uniform consistency and colour are obtained, this should be ideally carried out using a mechanical mixer. Mixing of 1 kg packs can be done by hand but care must be taken to ensure homogenous mixing. In cold weather, mixing will be aided if the containers are stored in a warm environment before use. APPLICATION For bonding concrete
sections, an even coating of product should be applied to both surfaces and
these brought together under light pressure. CURINGAny excess paste which exudes from the joint should be removed and the joint trowelled to a neat finish. The assembled sections should be protected from movement until the resin is set. Where Quickmast 341 is to be used as a bonding primer in the vertical or overhead position, an even layer of Quickmast 341 should be applied to the surface and worked well in to ensure good contact. The material to be bonded should then be placed after approximately 30 minutes at 25oC. (This time refers to the total elapsed time from mixing the product). For patch repairs, Quickmast 341 should be applied to the surface and finished to levels. A smooth surface will be aided by wetting the trowel sparingly with Quickmast solvent. Quickmast 341 can be applied to cracks or in accessible areas by means of a sealant gun.
While the material is wet, brush out any ridges left by the trowel. Quickmast 341 should not under any circumstance ve exposed to water before final set. Quickmast 341 should be allowed to cure for 24 hours at 20°C before being subjected to foot traffic. At
the same temperature, full mechanical and chemical properties are achieved
after 7 days (please consult our Technical Department for details of curing
times at other temperatures).
