When paint fails on a property, 90% of the time it comes down to poor preparation. Painting over mould on schools and houses is a common mistake that the owners don’t pick up on, however paint will start flaking 1-3 years after this has been done. 80% of painters do not waterblast and mould kill surfaces before painting. This one item could extend the life span of the coating for another 5 years and also make the next repaint easier.
In the commercial/residential sector issues with paint are basically unheard of. If however you use a cheap brand of paint, outside of the main suppliers Resene, Dulux or Wattyl, you are taking a huge risk. These paints from leading suppliers are made for New Zealand conditions and using another brand is asking for issues. Swimming pool and industrial coatings is another field, and yes paint issues do occur because of the method used to create them and the raw ingredients imported.
Signs of paint aging:
Key signs of paint breakdown are fading of colours or a chalky look. Once paint starts to fade its breakdown is becoming rapid, and between the major suppliers in New Zealand the difference in the coating after 5 years is massive. Some can start fading after two years, whilst others are showing minimal signs of gloss deterioration 7 years on.
Questions to consider when engaging a painting contractor:
Will they be around in three years time when I have an issue?
Have they detailed out what paint they are using?
Will they be chemical cleaning the property properly?
Are they used by other large clients?
Speak to their references – how did the handle issues?
To sum up- are warranty’s or relationships the lowest risk?
Many companies advertise a warranty but have you tried getting them back? The key to reducing your risk on painting projects is not in getting a long product or workmanship warranty but in employing a company that is reputable, long standing and has a large positive brand presence to maintain. The painting company should form a partnership with you as their client rather than view your project as just another paint job.
