Cold Weather Installation

Why does cold weather make cast vinyl difficult to install?

The winter months and colder temperatures create a multitude of problems for vinyl installers. Therefore it is important that we explain some of the physical characteristics of both the film and the substrate that are affected by these colder temperatures.
 
So what are the most common obstacles encountered during a cold weather installation?
  1. The vinyl can feel “stiff”’ and lose its ability to be easily conformed around curves and into recesses
  2. The adhesive can lose a great deal of its tack and won’t bond securely to the substrate’s surface.
  3. The ultimate bond level of the adhesive can take longer to be achieved.
  4. Condensation can form between the vinyl and the substrate, further impairing the bond level of the adhesive.

How can we overcome the effects of cold temperatures?

This is the eternal question that faces all manufacturers of vinyl films. The simple answer is to increase the ambient temperature of the installation environment, substrate, and vinyl. Only then will the film perform as we expect it to. So how is this achieved in cold weather installation?

A successful cold weather installation is more than achievable by following a few simple tips. This fleet vehicle is wrapped in DPF 6100XLP. (Wrapped by Elite Wraps UK)

The Installation Environment

The recommended ambient temperature of the installation area is between 59F – 95F (15C – 36C). Temperatures below this cause the film to become ‘stiff’ or ‘brittle’. Colder temperatures cause the plasticizers in the film to lose their elasticity. It is crucial that the temperature of the environment rises to the recommended levels. The vinyl will then regain its flexible characteristics. These temperature parameters also apply to the substrate. This may mean receiving the vehicle earlier. This will allow the surface temperature to assimilate with the environment. This will help prevent condensation, which will impair the adhesive bond. Placing IR or gas heaters around the vehicle can raise the ambient temperature of the installation area.

Warming the Substrate

Increasing the substrate temperature will also improve the bond between vinyl and surface. When the adhesive is cold, it remains hard and loses an amount of its initial tack. Then, the whetting out process is unable to occur. “Whetting out” refers to the effect of squeegee pressure and temperature, relative to the adhesive. Pressure softens the adhesive allowing it to flow and starts the process of bonding to a high level, and cold temperatures have a huge effect on this process. The low temperatures prevent the adhesive from activating effectively. Adding more squeegee pressure can also improve the adhesive bond during colder weather.

Vinyl and Adhesive

Increasing the temperature of the substrate, environment, and vinyl lessens the time the film needs to firmly adhere to the vehicle. There is no shortcut to this process. By increasing the temperature as explained above, the vinyl will be soft enough to manipulate around curves and recesses. The adhesive will be able to ‘wet out’ effectively. Post heating the entire vehicle will undoubtedly add time to the installation. But it will also ensure that the vinyl is adhering correctly.
