Towards a Comprehensive Understanding of Dirt Pickup Resistance

Calm and serene lake between complex surroundings
The fouling of exterior coating surfaces by dirt is no simple matter. The process is complex, dynamic, and varies in length and time. It also includes a range of confounding particle transport, attachment, and release mechanisms. While complex, strategic, multiscale testing and analysis combined with particle and surface science fundamentals can be used to isolate the dominant mechanisms. In this...

Factors Affecting Sealer Performance on Concrete

It is often assumed that solvent-based sealers give better performance than water-based formulations on concrete because the solvent-based sealers are thought to better penetrate into the concrete matrix. In practice, it can be difficult to measure actual penetration of a sealer into concrete, as dyes and colorants used to highlight the sealer may show different migration properties than the polymeric binder....

Sustainability, Durability, and Ease of Use Drive Exterior Wood Coating Developments

Man installing wood flooring in home
Despite growing interest around the world in the use of concrete and composite materials, wood remains widely used in exterior architectural applications, including siding, decking, fencing, and similar applications. Coatings continue to play an important role in maintaining the appearance and protecting the integrity of wood. “Exterior wood has conveyed quality and beauty for centuries, but that beauty requires significant...

Cationic Stain Blocking Primer Technology

House painting
Most water-based architectural stain blocking primers typically have only moderate stain blocking performance, and they are designed to lock stains in the primer coat rather than block stains. This leads to a major performance difference compared to solvent-based primers. Since the stain is visible in the dry film when a bleeding substrate is coated with water-based primer, the painter cannot tell...
