Technical Datasheet - Expansion Joints Aluminium, Brass or Stainless Steel Joint - MCA, MCB, MCS Product Description These expansion joint profiles offer 9mm EPDM expansion core vulcanised to Aluminium, Stainless Steel or Brass side plates, ideal for use with flooring surfaces which are laid using the thick bed or vibrating floor procedure and where there are special requirements in terms of edge protection, movement absorption and resistance to external influences, acids, alkalis or weathering. The profiles can be installed with or without screed anchors depending on the application area. Stainless Steel grade 304, Aluminium 6063,Brass CZ108. Dimensions and Colour Available in 2.5m in lengths See Movement Joint Colour chart for available infill colours. Anchors included @ 300mm intervals. British Standard BS 5385 recommends that a Joint should be able to absorb 20% of the width of the Joint in movement accommodation; these Joints far surpass the minimum requirement. The movement Joints fit this criteria for expansion and compression on a lateral basis. Check that the thickness of the covering/ flooring to be laid corresponds with the height of the selected profile. Verify the necessary length and cut the profile to the required measurement, using the proper tools. With a toothed-spatula, spread the adhesive on the laying surface. Apply anchors to profile where applicable. Support the profile to ensure position when screed is applied. When screed has dried, proceed with the laying of the floor, the profile should never protrude. Where to use Movement Joints Movement Joints must be installed in certain areas and positions to prevent tiles debonding from the Substrate, industry guidelines suggest that the maximum field should be no more than 10m in each direction but in practice, depending on the individual applications it tends to between 5-8m. British Standards (BS) 5385 covers the requirements and methods for movement joints applications. Part 3: 1989-Section 3-19.1.1 states the building designer should assess the magnitude of any stresses and decide where movement joints should be located taking into consideration all the relevant factors. Movement Joints must be installed directly above any changes in substrate or movement joints/Gaps in the substrate To achieve the most favorable performance, please follow the maintenance instructions below. 1. Regular maintenance of the Profile will help prolong the life of the product. A build up of dirt and grease can prove hazardous and also affect the appearance of the profile. 2. Firstly, any excess dirt should be removed by using a quality vacuum cleaner or a soft bristle brush. A harsh bristle will mark the material. 3. The profile should then be cleaned by using a soapless, neutral detergent in warm water on a damp cloth. They should then be rinsed with clean water, again using a soft, damp cloth. 4. Polishes will reduce anti-slip properties and solvent cleaners are not suitable
