High solids coatings can offer numerous advantages when compared to solvent-based coatings. Some of these advantages include better durability, faster drying times and little to no emission of volatile organic compounds (VOCs). However, high solids coatings are not a one size fits all solution and there are a few factors that need to be taken into consideration before applying these coatings on your project.
- Cost – High solids coatings are typically more expensive than traditional solvent-based paints. Although high solids coatings require fewer coatings to achieve the same film thickness as conventional paints, extra coats of a less expensive product may still turn out to be more economical.
- Workability – Another factor to consider is that high solids coatings are generally more difficult to work with and require more skill to apply correctly. Incorrect application of the coating can compromise its ability to offer protection to the substrate and affect its overall appearance. Also, specialized equipment may be required to apply the coating, therefore requiring the need for a trained operator.
- Surface preparation – As with all types of coatings, proper surface preparation is needed to ensure optimal coating performance. Inappropriate preparation can shorten the life of the coating, compromise the substrate protection and give rise to unsightly defects. Proper quality control and quality assurance measures are therefore essential to ensure that the coating is being applied to a properly prepared surface.
In summary, it is important to consider the specific application and limitations of the coating you intend to use to ensure that high solids are the way to go on your project.
