Exposed concrete does not require a choice between reliable waterproofing and a refined architectural finish. A coordinated coating system can preserve the performance of the waterproofing assembly while adding durable, intentional color to visible surfaces. 

Winter is here, and you may have surfaces that need coverage despite the cold weather.  It is important to understand the environmental conditions and limitations of cold weather application before proceeding with the application of any coating.

Review the cold-weather fluid-applied application instructions for detailed application guidelines. However, the application guidelines alone will not paint the full picture. Follow along for professional advice on applying in the (cold) field.

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. 

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.

The most common method employed to tie into an existing hot rubberized asphalt system is to use more hot applied asphalt. This involves using hot kettles and can present some jobsite challenges, such as mobilization issues, safety concerns and foul odor. Cold-applied membranes can address all these concerns. Consult the manufacturer of the cold liquid-applied membrane to verify approval of application procedures. Manufacturers may be able to offer case histories, detail drawings, and application guidelines to help provide technical support needed for tie-in methodology.

Most methods, however, will include the steps listed below.  

It’s common knowledge that colder temperatures can impact the curing of coatings. To achieve the optimum performance properties of the coating, special attention to the manufacturer’s application guidelines is needed.

Applications at colder temperatures, or below the manufacturer’s recommendations, require experienced contractors who are familiar with CIM products.
