Decorative Paint Tinters: Pros and Cons

Considering paint tinters? Les Baker weighs up the options.

The advantage of this product is to be able to use a common medium for tinting paints, either solvent or water based.

However, to make them work together the binding agent for the pigments has to be a surfactant (detergent/shampoo etc.) These products are used to emulsify oil spills in water, for example, to negate the old adage that “oils and water don’t mix”. The downside is that the surfactant has no integrity once it is incorporated into a paint film. The more that is used, the weaker the paint product becomes.

Decorative Paint manufacturers want to provide a wide range of pastel options for the consumer and in doing so, have to limit their use of Titanium Dioxide (white pigment) to thereby reduce the quantity of tinters that are needed to achieve the result. As the strength of the colour rises, so does the reduction in Titanium Dioxide.

These paint colours are then tinted from a “light tint base” (instead of a white base.) As the intensity of the desired colour increases, the base changes from “light” to “deep tint base”, meaning the Titanium Dioxide level is again reduced, and so on.

In the end, comes the statement. “Not recommended for exterior use”, or more blandly “Interior use only”. Commercially, this provides a range of decorative options that are acceptable and others that are not. However, when performance is the dictate, paints with in-house milled pigments will always be a better option. These usually are referred to as “standard” colours. This range can obviously be intermixed to achieve other shades, without affecting the design performance level… and are not compromised in integrity.

Ideally, binding the pigments into the resin matrix locks in the performance. On the other hand, a loose lattice of pigment and surfactant can only produce an inferior amalgam.

To add a further dimension of concern, most manufacturers of paint products, now “farm out” their tinter requirements to external operators who produce “Colourants”. At that point the paint manufacturers’ reliance is on the quality of those suppliers.

Norglass... devoted to educating people in paint

With 56 years experience in the surface coatings industry, which embraces paints, glues, clears and more, I have learnt one thing… you can never have too much knowledge about what product to use where.

A can of paint to most people is an unknown. They know it is a liquid and has colour and smell but that is where it ends, the rest is embroiled in the promotional hype.

Having lectured to countless people across the South Pacific Basin over 40 years, I quickly learned that explanations had to be in layman terms i.e. a varnish is a paint without the pigment (in simplistic terms), and consumers could relate to that. At venues across Australia I have had audiences sit for up to 4 hours, to try to get a better understanding of what product they need to suit their project, or solve their problem. As an example, a farmer who uses a stock crate to transport his cattle wants a paint product for his road train that is resistant to urine and faeces, or a consumer that needs a fish pond coating that won’t hurt the fish… getting the right information is the only solution.

That’s why at our Norglass website we have hundreds of pages of easy to understand guides and data sheets to walk the consumer through the minefield of mis-information… backed up with a Technical Advisory Service to fill in the blanks. It’s not just about knowing what product you need, it’s about having all the information so that you can save on money and labour. Rectifying a problem that has been wrongly assessed will usually be 3 to 4 times the original outlay… and that’s your money.

Winter is the best time to bring an old favorite back to life…

Whether you have a 40 foot yacht or an old wooden dinghy, the winter months are the perfect time to drag her out of the ocean & give her the once over she deserves.

A bit of elbow grease, the right product, advice & a systems approach will help the average “Do It Yourself” amateur achieve results every bit as good as the experts.

Because of the hundreds of variables over different types of boats and the climates & conditions they are exposed to, how to begin a repair & the technical details around it are vast. Getting it wrong can prove very expensive, however the right product and simple common sense advice will help avoid those DIY disasters that are all too common.

  • As a first step to achieving great results, make sure you understand the material you are working with, and the conditions in which you generally use your boat. Your boat may be made of timber, fibreglass, aluminium, steel or other, and each surface will react differently to the climate & conditions in which it is used. Established Marine brands, such as ours have informative “how to” guides on all surfaces available via this website. This will help sort out what your initial approach should be and the products required for the repair.
  • Don’t mix various paint company products. Where possible stick with the one brand all the way through for better, more cohesive results.
  • Preparation is key. Read surface preparation instructions carefully, these are on the label of the products you are using. If you do not understand the instructions, only take qualified advice, rather than accept hearsay advice. You can call our technical support line or speak to a qualified person at the store you purchased the product from.
  • Do not substitute solvents, use what is recommended. If using a 2 pack paint do not alter mixing ratios.
  • Do not cut corners or skip stages, use the number of coats recommended, and wait the recommended time between coats. Be aware of the conditions you are painting in, temperature and humidity can alter the characteristics of the paint.
