Smart Tips For Cold Weather Coatings Applications That Will Save You Time

Posted by Maribeth Taylor on Feb 8, 2018 11:30:00 AM

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 manufacturer’s recommendations, require experienced contractors who are familiar with CIM products. 

Smart tips for cold weather applications:

  • Plan ahead. Air and surface temperatures will affect the working and cure times of the coating.
  • Monitor temperatures. On cold, rainy, and windy days, the dew point and wind-chill, can account for moisture in the air as well as moisture formation on the substrate.
  • CIM coatings should be applied only when the substrate temperature is no less than 5°F above the dew point.

How to Dry Concrete Prior to a Coating Application

Posted by Jeff Raglani on Jan 15, 2018 1:30:00 AM

Coatings fail to bond to concrete for two reasons:   

  1. Lack of sufficient surface profile.
  2. Moisture in the concrete

Today, most coating manufacturers require concrete substrates to be dry (<5% moisture content) with low vapor transmission (< 3-5lbs per 1000 sq. ft./24 hours) before applying most types of membranes. This applies to both new and existing concrete substrates, although each may have its own set of moisture-related problems. For example, a 90-year-old poured-in-place partially buried concrete tank may face an entirely different set of circumstances from a newly constructed concrete slab with a steel tank mounted on it. Ultimately, the concrete needs to be dry prior to coating.

Don’t Let Environmental Conditions Ruin Your Next Coating Project

Posted by Maribeth Taylor on Oct 2, 2017 11:00:00 AM

Environmental conditions can wreak havoc throughout all phases of a coating application.  To maximize the longevity and performance of the coating, we need to monitor environmental conditions, utilize proper testing equipment, and maintain daily field logbooks to stay on the path to coating success!

Environmental Effects on Coatings

Environmental conditions refer to the air and surface temperatures, relative humidity, dew point, and wind speed; each of these can negatively impact the coating if not properly monitored. 

  • Air and surface temperatures are the first conditions to check when assessing the potential for effects on the working and curing time of the coating as well as moisture formation on the substrate. It is equally important to verify that temperatures arein line with the manufacturer’s product recommendations.
