PAINT STRIPPING – WHY?

PAINT STRIPPING – WHY?

Whether you are a professional painter, property owner, D.I.Y. painter, there will come a time when you will need to do some paint stripping. Paint Stripping adds a great deal of expense and time to an already time-consuming job. So, are the benefits worth all the hassle?

One answer   YES

5 Reasons you may need to strip a surface

  1. Paint has a History:
    The paint on your house has its own unique legacy. How long ago was it built and first painted, how many coats of paint were applied at the time, what types of paint were used, how were they applied, how many times has it been painted since the first time, what preparation was done with each repaint, what paints were used for these repaints etc etc. It is very rare that all these questions can be answered definitively and as most of the paint manufactures guarantee state ‘this guarantee does not cover paint failure caused by any breakdown of coatings applied previously.’
  2. Paint has a Memory:
    Paint is designed to be flexible, expanding in the heat and shrinking in the cold, newer technology paints have even more elasticity than their predecessors. Depending on how old the paint is will depend on how old its memories are, to clarify let’s imagine paint expands +/- 10%, the paint gets used to this, and happily will expand and contract to this level.  However, you then apply a nice new technology paint that expands +/- 20%, when this new coating starts expanding it applies unseen pressure on the existing coating, which will cause it to reach a breaking point, more often than not the result is little air-filled blisters that appear on the surface of the paint work.
  3. Paint has a Lifespan:
    Most paints are only designed to last a designated period before breaking down and requiring repainting. If a paint has a lifespan of 10 years but was applied 30 years ago, can it still be trusted?  When dealing with multiple layers of paint, applied at different times, can they all be trusted to still perform past their recommended lifespan and can they perform in conjunction with each other?
  4. Paint may have Lead:
    Lead was still one of the main components of house paint until 1979.  If your house was painted prior to this then it is likely that the paint will have some level of lead, this does not mean to say, if it was painted since then it won’t have lead as many a shed still has plenty of left over tins of paint, that were used over subsequent years. The best way to check for lead paint on your property, is with a lead-base testing kit. Available from most good paint suppliers.
  5. Paint has a Light Reflectance Value (LVR):
    Changing colour can have a major impact on the performance of your new paint job, particularly when changing to a darker colour as these will heat up faster than lighter colours, resulting in greater expansion that will inevitably cause the previous layers of paint to start blistering. ‘Black has a light reflectance value of 0% and absorbs all light. The surfaces are consequently very dark and can get very hot.  In contrast, white has a light reflectance value of 100% and keeps a building light and cool. All colours fit within these extremes.’

Painting a home is a major investment of both time and money, whether you are a professional or a DIYer, we all want a job that will look good and last a long time.  Sometimes the best result is only by starting from scratch. Stripping the paint off means you recreate a new legacy of paint work with no memory, no lead, no expired life expectancy and no unknown history.

No house project is too big or small for paint stripping before painting. Have a look at this before an after example to show the lengths to which we go to get that perfect painted finish!
