Apply a coat of Spectra 2in1 Multi Primer (Interior/Exterior). For best results, fill up dents with suitable Nebulon Exmpire Wall Putty applied in thin layers. Wherever application of spot putty or full putty is resorted to, a coat of Spectra is recommended as an undercoat on top of the putty for eliminating the patchy appearance in final coats. Nebulon Distemper is supplied as a thick paste, and water is to be added slowly to the paste while stirring to obtain brushing consistency.

Normally 500-600 ml of water is required for 1 kg of distemper. However, the amount of water needed will depend upon the porosity and texture of the substrate. Apply 2-3 coats by brushing, keeping an inter-coat interval of about 4 hours between successive coats. Shades of your own choice can also be made by tinting it with Universal Stainer. The tinting process must be carried out before thinning.
