Question

What is the difference between water-based and solvent-based products?

Answer

Solvent-based products typically contain high levels of Volatile Organic Compound (VOC) and were traditionally for use on wood and metal surfaces, giving a glossy finish but associated with longer drying times and a strong smell, However, water-based products have typically low levels of VOC and have come along way over recent years, with many companies offering a water-based paint equivalent to a solvent-based option.  The benefits of a water-based product includes quicker drying times, less smell, and easier cleaning up with brushes and rollers being able to be rinsed with water rather than white spirit, making the whole decorating process more environmentally friendly.

Washing solvent-based paint from brushes required the use of white spirit or solvent-based brush cleaners, which in themselves release VOCs when used, and are difficult to dispose of because of their hazardous nature. Therefore, using water-based paints, where brushes can be washed in soapy water, can further reduce the environmental impact of decorating.
