In Shop Kitchen Cabinet Door Spraying vs At Home Tent/Trailer set up & how Temperature & Humidity are KEY Factors for proper adhesion.

In-Shop Spraying

• Controlled Environment: The shop provides a controlled environment with more consistent temperature and humidity, reducing the risk of defects & adhesion in the finish.

• Quality of Finish: Professional-grade equipment can be used to achieve a high-quality, smooth finish.

• Efficiency: Spraying in a shop can be quicker due to the availability of specialized tools and techniques. Transportation however of doors back & forth does add time & cost to projects.

• Safety: Spraying indoors is done with proper ventilation and safety measures in place, minimizing exposure to harmful chemicals created by 2K products.

• Less Weather Impact: No risk of weather-related issues such as dust, rain, humidity or temperature fluctuations affecting the finish quality & it's ability to bond as best as possible.

  
  

Tent or Trailer Setup at Home

• Weather Exposure: Tent & Trailer setups are vulnerable to weather conditions like wind, humidity & temperature, which can lead to imperfections in the finish due to dust, moisture, or temperature changes.

• Accessibility: Spraying at home can be more convenient for the refinisher, eliminating the need for transportation of cabinet doors.

• Cost-Effective: Setting up a tent can be less expensive than using a professional shop, especially for smaller projects.

• Flexibility: Home setups allow for more flexibility in timing and scheduling, accommodating the homeowner’s needs such as faster turn around times.

• Potential Quality Issues: The quality of the finish may suffer due to environmental factors that drastically swing in our region, leading to a less professional appearance.

• Neighbours: Having a tent set up will surely mean exhausting fumes and possible overspray into the area around your home & exposing the smell & any overspray to your neighbours. Where 2K products are concerned the hardener is toxic & one should consider this when exposing this to your neighbours.

  
  

  In-Shop Spraying

  
  

  • Controlled Environment: A shop offers a stable environment with consistent temperature and humidity, minimizing the chances of defects and adhesion issues in the finish.

  • Quality of Finish: High-quality, smooth finishes can be achieved using professional-grade equipment.

  • Efficiency: Spraying in a shop is often faster due to the availability of specialized tools and techniques, although transporting doors back and forth adds time and cost to projects.

  • Safety: Indoor spraying is conducted with proper ventilation and safety measures, reducing exposure to harmful chemicals from 2K products.

  • Less Weather Impact: There is no risk of weather-related issues like dust, rain, humidity, or temperature changes affecting the finish quality and its bonding ability.

    
    

  Tent Setup at Home

  
  

  • Weather Exposure: Tent and trailer setups are susceptible to weather conditions such as wind, humidity, and temperature, which can cause finish imperfections due to dust, moisture, or temperature variations.

  • Accessibility: Spraying at home is more convenient for the refinisher, removing the need to transport cabinet doors.

  • Cost-Effective: Setting up a tent can be cheaper than using a professional shop, particularly for smaller projects.

  • Flexibility: Home setups provide greater flexibility in timing and scheduling, accommodating the homeowner’s needs for quicker turnaround times.

  • Potential Quality Issues: Environmental factors in the region can affect finish quality, resulting in a less professional look.

  • Neighbours: Setting up a tent may lead to fumes and possible overspray affecting the area around your home, exposing neighbors to smells and overspray. With 2K products, the hardener is toxic, so this should be considered in relation to your neighbors.

Conclusion

In addition to the apparent differences in wind and dust control, heat and humidity significantly impact modern 1K and 2K Cross-linking Urethanes.

Nearly every brand, including Italian ones, has specific limits for proper adhesion and curing, ensuring the final result not only looks good but also adheres and performs as expected.

Most brands provide the following guidelines:

The recommended application temperature ranges from 60°F to 77°F (15.5°C to 25°C) to achieve optimal curing, bonding, and durability. Straying from this range can compromise longevity. Seasonal changes are crucial factors.

Humidity is even more critical, with 40% to 50% being ideal. You can extend it to 60% with minimal issues, but exceeding 60% can hinder proper water evaporation, affecting curing more in 2K than 1K coatings due to the hardener's timed setup. High temperatures accelerate this process, and humidity can become trapped between the surface and cabinet door, reducing bonding and cross-linking effectiveness. Consequently, 2K will not perform as intended, lacking the designed chemical and moisture resistance.

The choice between in-shop spraying and a tent setup at home depends on factors like desired finish quality, budget, and convenience. In-shop spraying generally provides better quality and consistency, while tent setups offer flexibility and cost savings but come with higher weather-related risks. Applying these coatings in over 60% humidity will diminish the finish quality regardless of the brand.

Shop environments are much easier to control compared to outdoor conditions where temperature and humidity cannot be effectively managed.

Many businesses offer the at-home system as a premium service, which is faster than a shop system, and they charge more for it than conventional in-shop systems for some reason.

Providing this type of service is clearly limited in Southern Ontario due to seasonal variations.

Ultimately, the tent system has several limitations, which is why we have chosen the in-shop approach since 2008. Having completed over 935 kitchens with our system, we know it delivers the best possible outcome for longevity given the controls we have.
