The chilly weather typically places a damper on any protecting coatings project. For one, productiveness is minimal in the winter months than in spring or fall. Painters, irrespective of how skilled, discover themselves hindered by the cold temperatures and the freezing atmosphere. Even tools will not be 100 % optimum when operated in cold weather.
Within the protective coatings business, the cruel winter season is often a gradual time for painting actions, significantly of water storage tanks. And since summer is a vital time when water availability is essential, painting activities are also gradual within the summer time months. That leaves only the spring and fall seasons when coatings exercise can proceed unhindered.
To acquire extra time for painting purposes, contractors try to overcome the challenges of painting water tanks in cold weather, and have made progress on this regard through ambient temperature management, heat loss prevention, and progressive chilly-weather utility techniques and protective coating methods.
Environmental Temperature for Winter Painting
In any season, painting actions akin to floor preparation, actual application, post-application, and curing/drying activities are very dependent on environmental circumstances. Even the storage and disposal of protective coatings are delicate to the circumstances of the work surroundings and more so in wintertime, when the temperature is the toughest obstacle in maintaining the circumstances appropriate for painting actions.
The key to maintaining the right painting temperature in winter is to pipe in additional heat to the facility interior. When the cold intensifies exterior, more heat should be generated inside, to maintain ambient temperatures. For storage tanks, the identical hold true. The tank’s surface should achieve the correct temperature to counter heat dissipation that impacts the performance of cold-cure protecting coatings and the general high quality of the painting utility.
Sustaining Environmental Temperature
The American Water Works Association (AWWA) has an outstanding reference for working with steel storage tanks in cold weather operations. One crucial knowledge contained within the manual is the heat loss chart that defines the connection between the tank’s inside and exterior temperatures, and how a lot heat is misplaced given these temperature ranges.
To stop losing essential heat in storage tanks, there’s a must setup a great insulator. The tank partitions provide some insulation, which is determined by the toughness of the protecting coatings installed in the tank floor. In some cases, thermal blankets or a heat containment system should be setup within the duration of the tank coating exercise.
Heat will also be forcibly added to keep up ambient temperature and compensate for heat loss. This typically requires heating the tank, accruing gasoline and heating costs.
Successful Winter Painting
Chilly-weather painting requires relevant changes in the way protective coatings contractors work, but following the guidelines or guideline below can make tank painting software easier to implement:
- 1. A clear painting implementation plan
- 2. An in depth cold-weather protecting coatings product specifications
- three. A comprehensive listing of tools to be used, from dehumidifiers, heating and containment techniques
- 4. Manpower requirements
- 5. Fuel and other resource costs
- 6. Work schedule taking into consideration disruptive weather patterns
7. A contingency plan when delaying events come up, like inclement weather, tools repairs, longer curing time, and emergency circumstances, among others.
