Joint sealants are typically available in cartridges (either single or dual components). Each cartridge style is designed for specific applications and environments. Generally, cartridges are ideal for small applications such as penetrations, joints, cracks, and many other repairs requiring waterproofing or chemical containment. Partially used cartridges can be stored and reused later. Instant mixing and dispensing of sealants are often performed via a hand, air, or battery-powered caulking gun.   

In this article, we'll discuss:

1. The advantages of using cartridges over other application methods
2. The basic differences between single-component and dual-component cartridge sealants
3. How to set up a sealant dispensing gun
4. How to store a partially used sealant cartridge

Industrial waterproofing projects require a specialized coating system to meet specific coating specifications. The size and scope of work will influence the application method of these coatings. 

For this discussion, we will review factors to consider when spray-applying waterproof coatings on large-scale projects and the types of spray equipment needed to apply waterproofing materials. Projects with an abundance of vertical walls, overhead surfaces, and minimal risk for overspray are generally excellent candidates for utilizing spray equipment.  

Typically, the spray equipment used for waterproofing products can be classified as airless, air-assisted airless, or plural component spray equipment. Always use equipment recommended by the waterproofing material manufacturer.

Cold temperatures can impact the curing of coatings.  Applications at colder temperatures, or below the manufacturer’s recommendations, require experienced contractors familiar with CIM waterproofing products.  To achieve the best results, it is important to pay attention to the manufacturer’s application procedures. 

Identifying termination points and properly terminating waterproof coatings are two critical aspects of a waterproofing system’s long-term success. Whether you are applying the coating system to a roof, floor, tank, or fountain; in hot or cold climates; or to concrete, wood, steel, or any other construction materials, correctly terminating the waterproofing system is essential. 

Termination points are areas where the waterproofing membrane stops or is no longer applied.

With many varieties of elastomeric coatings on the market, it should be no surprise that there are many different application methods to consider. So, how do you choose the best plan for your next project? 

This article will focus on polyurethane, cold, fluid-applied, elastomeric waterproofing coatings. These products can be hand-applied using a brush, roller, or squeegee or with specialized spray equipment. The application method is often predicated by project conditions that influence the contractor's ability to apply the material as a uniform coating at the required thickness.

There's no avoiding the fact that concrete contains moisture, yet a critical component for successful adhesion of a coating system to a concrete substrate is having a dry substrate. Knowing how to test for moisture and addressing the conditions causing it are things all contractors should familiarize themselves with before applying coatings. Consulting with the coating manufacturer and reviewing the manufacturer's technical data sheets are excellent ways to gain this information. 

The construction industry faces many safety challenges as the work environment is always changing in response to the specific job at hand. One of the most challenging environments is working within confined spaces. There are numerous safety regulations in place meant to keep construction workers safe.

Environmental conditions can wreak havoc throughout all phases of a coating’s application, but what happens when the wrong tools are used during the mixing process or the material is mixed incorrectly?  To avoid negative effects of improper mixing, the manufacturer typically provide technical datasheets, application guidelines, and technical support to aid in the completion of a successful application. 

Cooling towers are often considered a challenging environment for coating systems.
