The types of paint remover available
These are usually used to clean walls of any coverings they have had applied to them, and to clean the bare surface under the paints. There are various types of paint remover available to you from most outlets that deal in industrial paint supplies. These can come in many forms that depends on the job you have to take on, the most common that you would likely know is white spirits commercially available to most industries. Caustic paint strippers function by breaking the chemical bonds of the paint and allowing the finish to be removed, the item in question I.e walls, floors or furniture, have to then be neutralised through the application of various chemicals. This can be a simple application of vinegar and water to methylene chloride based chemicals. The application of paints to the now prepared surface should wait first, it is always best to test the PH value of the surface you are preparing to paint, this value should typically be PH7 or there abouts. Also, you should check what type of surface it is you are to paint, if it’s porous, then you should clean again thoroughly before applying, as porous surfaces can bleed over time undoing all the work you have put into the wall painting.
Alternatives to the caustic type
Another method of removing paints is by the application of solvents, as up there, the most widely used is white spirits, this can come in various forms of liquid or gel making it applicable to walls. This operates when applied to the wall and the paint film is penetrated by the active molecules in the stripper causing the paint to start swelling, from the outer layer to the adhesive layer which in turn causes the paint to ‘bubble up’ and start separating from the wall itself making it easier to remove. Another way to remove paint is through a non chemical means, usually by the way of a heat gun. This is largely by the use of an electric gun, gone are the days of using paraffin or gas versions, this heats up the paint causing it to go soft. You are then able to use a paint stripper tool to start scraping away the remaining paint.
