The Stucco can be applied on new interior plaster as well as on to sound previously painted interior surfaces. Always ensure the surface is prepared in accordance with normal practice before you apply this stucco. The following considerations must be taken into account prior to application of Fossilcote Interior Stucco.
Surface and Preparation
- On new Plaster that’s chase mark free and shrinkage crack free, apply directly to substrate and always dampen the wall for better curing prior to applying Fossilcote Interior Stucco. On a new Plaster with patching and chase marks, apply one mortar bind slurry coat as per data sheet, followed by one coat Down to Earth Textured Primer and then apply Fossilcote Interior Stucco.
- On previously painted surfaces, if high sheen sand with 40 grit sandpaper and apply one coat Down to Earth Textured Primer then apply Fossilcote Interior Stucco.
- On Unsound previously painted surfaces e.g. Lime washed, patched and repaired walls remove all chalky loose material by wire brush, sandpaper or mechanical sander, and then apply one mortar bind slurry coat as per data sheet. Then apply one coat Down to Earth Coarse Aggregate Primer.
Application and Spread Rate
Fossilcote Interior Stucco will cover approximately 18-20 sqm. Per bag onto well finished conventional plaster. It will not perform as it should if applied more than 3mm thick. Use 4 – 6 liters of water per 25kg Bag to achieve a stiff buttery consistency, which does not slump.
Fossilcote Interior Stucco is applied to a thickness of 2 – 3mm by steel trowel, and then allowed to stiffen. Stiffening will occur in approximately 30 minutes in normal conditions. Remember in cold weather, stiffing time can double and on prepared painted surfaces, drying will take longer as hydration only occurs from the exterior. After stiffening, finish the product off with a wet steel trowel. Do not flick more water onto the surface. Use short 30 – 50cm random movements with the trowel.
When applying Interior Stucco with fleck there are two ways to expose the added fleck. You can do so by either finishing with a sponge float to remove the “fat” from the surface and expose the fleck, or by sanding with 220 grit water paper once the Stucco is dry. When dry, lightly sand with 220 grit water paper to remove any surface imperfections which may be caused by the applicators trowel. Wipe off all dust with a damp cloth. Finally, apply two coats of Fossilcote Mattseal to enhance washability.
