INSTALLATION 13 External Angles Using a 4” taping knife, apply a 50mm wide band of GTEC Joint Filler or GTEC Allset Xtra on each side of the angle. 14 External Angles Bed the tape onto the corner. Once bedded, cover each side of the tape with a 100mm band of GTEC Joint Filler, feathered out onto plasterboard face. When set hard, apply a second coat of GTEC Joint Filler, feathered out 50 to 60mm beyond the edges of the first coat. 15 External Angles When set hard, apply a finishing coat of air-drying compound or GTEC Allset Xtra, feathered out 50 to 60mm beyond the second coat. Now allow to dry fully. 86 THE INSTALLATION HANDBOOK 2008
Lafarge GTEC Taping and Jointing System Lafarge GTEC Taping and Jointing System is used for the seamless jointing of plasterboard to walls and ceilings. Applications • Jointing of tapered edge plasterboard. • Jointing all flat, internal and external corner joints. • Jointing GTEC Profiles with plasterboard. Benefits • Continuous walls and ceilings created with ease. • Stronger joints than other alternative methods. • Fast setting and drying times, allow quicker decoration. • Only a small amount of material required on site compared to wet plaster. Good Site Practice • Store jointing compounds and tapes in dry conditions, protected from damp and extreme temperatures. • When mixing powdered jointing compounds always leave to stand for the recommended time indicated on packaging. • Always ensure joints are fully dried before decoration. • Lafarge recommends the use of a coat of GTEC Universal Sealer prior to decoration. • Never use air-drying jointing compounds under GTEC Joint Filler or GTEC Allset Xtra. • Always ensure compounds are used in the correct sequence. Jointing Compounds All GTEC jointing compounds finish white, are exceptionally smooth to work with, and easy to sand for a very fine finish. <strong>The</strong>re are six types: (a) GTEC Smartmix Vinyl based pre-mixed jointing compound for air-drying applications. Suitable for bedding tapes and finishing joints by the Premier or similar automatic taping tools or by hand. GTEC Smartmix is a three coat application system. (b) GTEC Smartmix Xtra is a lightweight, air drying pre-mixed joint cement for hand or mechanical jointing. 2 coat application. (c) GTEC Joint Cement is an air drying joint cement for hand or mechanical jointing. 3 stage application. (d) GTEC Joint Cement Xtra A lightweight air drying compound for bedding tapes and finishing joints, either by hand or using a machine. GTEC Joint Cement Xtra allows the jointing operation to be completed in two stages. (e) GTEC Joint Filler a setting compound for hand jointing. Not suitable for finishing. (f) GTEC Allset Xtra is a setting compound for hand jointing with low shrinkage. 2 coat application. Joint Tape GTEC Joint Tape is a white, perforated, cross fibre paper tape. hand or mechanically applied, which provides a superior level of joint reinforcement. External Corner Protection <strong>The</strong>re are two types: (a) GTEC Flex Tape is a cross fibre tape reinforced with rust resistant steel strips. Bedded into position using GTEC setting compounds. No waste - cut to the required length using Tin Snips. (b) GTEC Tape-Ons are paper tape beads reinforced with galvanised metal, provides clean, crisp angles, wax coated to reduce paper burr. Pre-formed to 90°.
