Technical Datasheet - Expansion Joints PVC Movement & Perimeter Joint - MLB Product Description Genesis MLB is a Light Duty PVC Movement Joint designed to protect the edge of the floor covering from light traffic (e.g. foot traffic). One of the flanges which is primarily designed to sit under the floor covering can be removed by hand on site by snapping along the V shaped groove in the extrusion. This now modified profile with one flange is perfect as a perimeter joint providing a 10mm cushion around the entire installation between the floor covering and the wall. Dimensions and Colour Available in 2.5m lengths. 10mm and 12.5mm depths. See Movement Joint Colour chart for available infill colours. 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 Performance 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. To achieve the most favorable performance, please follow the maintenance instructions below. Where to use Movement Joints 1. Ensure the correct Depth of Profile is selected according to the tile depth. 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. Using a suitable Notched Trowel spread Tile Adhesive onto the floor in accordance with the manufacturers guidelines. 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 Property Vicat Softening Point Tensile Modulus Yield Stress Yield Strain Elongation at Failure Flexural Modulus Tensile Impact Strength 3. Firmly bed the adhesive into the adhesive in the correct location - make sure that the adhesive penetrates the holes in the flange. 4. Spread the adhesive over the the anchoring legs and bed the tiles firmly into the adhesive (best practice is for the profile to be approximately 1mm lower than the Tile). 5. A grout joint should be left between the tile and the profile. Test Method ISO 306 ASTM D638 ASTM D638 ASTM D638 ASTM D638 ISO 178 ISO 8256 P.V.C.
