Specification.
Preparation of previously lime washed surface.
Remove by the most appropriate means, all loose, defective or otherwise suspect material back to a firm edge. Treat all organic growth as necessary, ensuring the surface is clean and and free from all dust, dirt and any other contaminates.
Make good all defective area with a lime based mortar and allow to dry.
All surface must be thoroughly dry, although, it is necessary to lightly wet (dampen) the surface by brush or fine spray to reduce the surface porosity immediately prior to applying limewash.
Painting
Apply each coat (normally 3-4 coats) as required allowing each coat to thoroughly dry out before applying the following coat.
Apply in accordance with selected manufactures recommendations.
Note:
Ensure the material has been thinned in accordance with manufacturers instruction.
Mix the limewash on a regular basis by hand or mechanical means
Dampen the surface prior to each coat being applied and paint small areas at any one time to keeping the wet edge open.
When applying limewash the wet film opacity appears poor but on drying out the full colour and opacity becomes apparent.
Do not apply to none lime based or none porous surfaces in low or high temperatures.
For Limewash to harden and gain strength it is necessary for it to dry out slowly therefore for the first 3-4 hours the applied material should be dampened with a mist coat of water.
Current water based paints are not compatible with Limewash
