Brush Graining. Health and Safety. Environment.
Cleanliness and unrestricted work area is most important to create as far as possible a dust free environment.
As solvents and rag are used it is important that all used rag/cloths are spread out flat after use to allow the solvents to evaporate. Not doing this could lead to combustion and fire.
Surface preparation
Ensure all loose defective material is removed back to a firm edge. Fill all surface imperfections with a suitable wood filler/surfacer and then thoroughly rub down with suitable abrasive paper preferably wet to leave a smooth, sound finish.
One or two coats of an oil based ground coat in the appropriate colour should be applied and when dry sanded down with 1000 grade wet or dry to remove any surface nibs, rinsed with clean water and allowed to dry.
Apply selected scumble in accordance with the manufactures recommendations and after completing the required grain design and when dry apply one coat of selected clear satin varnish.
Note: All wet material should be strained before use to remove any contaminates and before use all surfaces should be tack ragged down to remove any surface dust.
