Lead Paint Removal

Re-painting an older property? - YOU MUST READ THIS AND WATCH THE VIDEO

It's becoming increasingly common when undertaking painting of older weatherboard properties that the existing paint system is no longer able to support the application of a new acrylic paint system. When prepared for re-painting, the paint coating appears sound, however shortly after painting blistering and peeling can become evident. The peeling and blistering goes back through many coats to the original primers when the weatherboard was first painted, often many years before.

The advent of modern acrylic paint systems, with their ability to expand and contract with temperature, places massive tension on the previous coats. These previous coats are often many years old and were never intended to last the 30 plus years they have sat on the weatherboards and broad wall areas for. Old enamel paint is impervious and will not allow the transfer of vapour to the outside of the house, as acrylics will, this means moisture will build up behind the old enamel and create a blister, and if the enamel is already weakened by the new acrylics over the years, bubbling will be worse. The result of this is that any new paint applied to your house will result in your house looking like it has the chicken pox with large blisters everywhere, not the look I am sure you were looking for in a new paint job of your most prized asset. Feel free to call us to come and assess your home and we can advise you the best way to proceed.

Complete Coatings recommends that consideration be given to removing all existing paint coatings from timber weatherboards and any other broad wall surfaces to be painted that are older than 25 years. While this does increase the cost of re-painting, failure to remove the existing coating can result in the failure of the new coating with costly ramifications for the home owner.

Testing for lead should also be undertaken prior to the removal of the coating. It is a common fact that properties up to the 1980's have been painted with lead based paint. Lead in paint, and the contaminated dust and soil it generates is now recognised as a significant source of lead toxicity, and is an important health issue.
Complete Coatings recognises these issues and has researched available options for the removal of lead based paint. We have found a process that not only strips paint efficiently, but is now endorsed by the New Zealand Master Painters Association for the safe removal of lead based paint. The use of water in the sanding process provides many benefits as listed below:

Used in conjunction with our Enviromat it is the safest system for the removal of lead based painted surfaces.  There is no lead based dust and the sanded lead particles are safely collected in the Enviromat with the water passing through the mat.  For this reason it is now the NZ Master Painters preferred system for the removal of lead based paint.

  • Water prevents heat build-up causing substrate damage.
  • Water with the sander means that the slurry from lead based paints can easily be collected in the Enviromat.
  • There is no need for power cables so we don’t need access to the property.
  • It is the most efficient process for the removal of existing paint systems.
