Application
Fix laths if required. Allow 25 no metre lengths to the square metre.
Make sure surfaces are sound. Wet surfaces thoroughly. Dub out any large voids using Tradlym Mortar BM2. Allow dubbing out to cure.
First coat
Wet surface thoroughly. Apply 1st backing coat of Tradlym Backing with Hair/Fibre to a maximum depth of 10mm. If application is to laths sufficient mortar must be pushed through the lath to form “hooks” to take the weight of the remaining mortar. Allow to cure (up to 10 days) misting occasionally if plaster starts to dry out. Scratch to receive 2nd coat.
Second coat
Wet 1st coat. Apply 2nd coat of Tradlym Backing with Hair/Fibre and straighten up. Allow to cure again misting if necessary. Scratch with devil float.
Finish coat.
Wet 2nd coat. Apply Tradlym Fine Finish plaster to a maximum depth of 4mm.
Protect all work from strong sunlight. See the Tradlym on-site guide for further advice.
