Uses Construction Adhesive is suitable for bonding a wide range of common building materials such as: „ Timber, metal, cementitious and plaster sheets to timber or metal studs „ Plywood and particle board flooring sheets to floor joists „ Metal sidings to metal or timber studs „ Metal, timber, and other sheet or plank materials to concrete, plaster, or other rigid surfaces „ Polystyrene foam and some plastics „ Most bonding applications where a high strength, gap filling, one component adhesive is required Advantages „ Easy and economical to apply „ Fast setting „ Eliminates the need for screws or nails „ Provides a tough permanent bond „ Good gap filling properties „ Bonds to most building construction materials Description Construction Adhesive, a one part gap filling synthetic rubber adhesive. It is a carefully formulated blend of synthetic rubber and resins, inorganic fillers, colouring and preservative compounds borne in a specially selected blend of organic solvents designed to be compatible with and bond strongly to most common building materials. Construction Adhesive is suitable for bonding plywood, particle board, hardboard, decorative laminates, metals, concrete and most composition boards to themselves or to each other. Construction Adhesive is supplied in cartridges for ease of application. Technical Support Parchem offers a comprehensive range of high performance, high quality repair, maintenance and construction products. In addition, the company offers a technical support package to specifiers, end-users and contractors, as well as on-site technical assistance. Properties Form: Non slump paste Physical or chemical change: Solvent loss Slump resistance: Good Permissible open time: Dependent on surfaces and ambient conditions. Up to 10 minutes when used as ‘wet stick’ method. Up to 30 minutes when used as contact adhesive Service temperature range: Up to 100°C Chemical resistance: Resistant to water, dilute acid and alkalis, mould and fungi Application Instructions Surface preparation All surfaces should be clean and dry. Loose dirt and contaminants should be removed by wire brushing. Painted surfaces should be roughened, oil or grease should be removed from metal surfaces using Solvent 10 and timber should be dressed and substantially free from twists. Damp timber surfaces can be bonded, provided no free water on surface, however this may modify drying time and early strength properties, so Construction Adhesive should not be used as a contact adhesive on these surfaces without initial testing. Application Apply directly from cartridge to give the required bead size. Flooring is usually bonded using the “Wet Stick” method and wall panelling may be applied with this method or by the more common “Dry Stick” or contact method. Apply Construction Adhesive to the base material, using 5 - 8 mm beads for fixing wallboards and 8 - 12 mm beads for flooring. Note that smaller or larger beads than those specified may be suitable where there is an exact fit of components or where large gaps are obvious, however initial testing is recommended to ensure suitability. Beads should be continuous for full length of studs or joists. Where applying to a flat sheet surface, space beads 200 - 400 mm apart. Only sufficient adhesive should be applied at one time to fix one panel or board. Locate panel onto base material as soon as possible to ensure adequate transfer of adhesive, then proceed as follows.
