Sustainable Low VOC meeting sustainable building project requirements.
Application Test for desired consistency depending on application method to be used. MastaLine is ready to use for hand trowelling. For mechanical tools, if necessary add clean tap water in small amounts and mix until desired consistency is achieved. If mixing MastaLine, note that overmixing may introduce air bubbles. As with all compounds, excessive thinning may cause cracking or increased shrinkage. Do not mix with any other material. Maintain a minimum 13ºC working temperature during application and drying. When using MastaLine for all three coats, joints must be back-blocked. MastaMate Paper Tape is recommended for use with MastaLine. For a stronger joint, use MastaMate Paper Tape and bedding cement for the first two coats, with MastaLine as the final coat. Allow MastaLine to dry completely between coats and approximately 24 - 48 hours before sanding. Sand lightly by hand using 150 grit paper or 180 sanding mesh. When using an electric sander use 220 grit paper. MastaLine will accept most types of decorative finishes. In accordance with AS/NZS 2311 Guide to the painting of buildings, a three coat paint system must be used. This consists of a sealer/undercoat and two coats of paint.
