High pressure waterblasting prior to painting can dramatically reduce preparation time required.
We use a safe, environmentally friendly cleaning agent to clean away moss, mould, mould spores, dirt and grime. Then the dirty residue is washed away using a high pressure wash. The high pressure wash will also remove a large proportion of any old, flaky paint.
This process does not eliminate the need for scraping and sanding in preparation for painting, but it does provide a stable, clean, oil and dust free surface prior to beginning paint work.
