Clayworks’ pigmented clay plaster, has a vast number of qualities such as it can regulate interior humidity and temperature, absorbs odour and can buffer sound, it is biodegradable and contains no chemical ingredients making it an ideal option for a variety of applications.
Walling surfaces: Suitable for use on most stable internal surfaces when properly prepared. Surfaces with too much or too little suction, and no mechanical key must first be primed with a suitable primer. Such surfaces include plasterboard or gypsum plaster surfaces. Rough surfaces require a straightening coat of lime or clay. Not to be used in areas in direct contact with moisture or excessively damp areas, although can be used in areas of high humidity, such as bathrooms and kitchens.
Application: Applied in the conventional manner with a hawk and laying on trowel. Can also be applied with a spray machine. Application is similar to gypsum with the exception of the finishing process. A smooth finish is preferred for durability and cleaning. This is achieved by hard polishing with a plastic trowel. However, an open grained, more textured finish can be achieved using a damp sponge to lose trowel marks. This is often a more suitable finishing approach for undulating surfaces.
Finishing: Best finished with Clayworks protective glaze for maximum damage resistance. Can be painted with microporous paint or pigmented protective glaze for an interesting decorative effect.
Drying times: Dependent on ambient conditions in the room, and rates of absorption from the background material. In ideal conditions, the plaster should be fully dry within 24 hours, but can take up to 48 hours. Good air circulation is encouraged during and after application. Low, even heat can be used in cold conditions, but must be used with caution as it can cause hairline cracks in the plaster if it dries too quickly.
Working conditions: Application should not proceed when temperatures fall below 5 degrees centigrade or rise above 30 degrees centigrade.
Cleaning: Wipe gently with a soft, damp sponge, if it has been finished previously with Clayworks protective glaze.
