Greenhouse Paint Used to Control Light and Heat
Posted on September 14 2023
Frank D. wanted to grow herbs and vegetables in his backyard and put up a Parlam Greenhouse to do so. The problem was he needed to eliminate all light pollution and reduce the heat from the sun and streetlights. Plus, with the grow lights on at night it really lit up the backyard and the neighbors…
Before - Greenhouse lighting up the backyard.To best control light going into and out of the greenhouse, Frank decided to paint the clear side panels to make them opaque. However, he wanted to retain the clear front and roof for natural light and heat on cold or cloudy days, and to enable him to see the plants when he wanted to. For this he engineered a system using a tarp as a shade that could easily be rolled up and down.
Using ColorBond LVP to Paint a Greenhouse
When it came to painting the sides, Frank found he needed to find a material that would properly adhere to the polycarbonate panels, and ColorBond LVP was just what he needed to paint a greenhouse. First, he applied ColorBond Adhesion Promoter and then white LVP Refinisher. Seeing the white painted panels where translucent and lit up at night, Frank applied black LVP refinisher over the white to block the light, but black absorbed the heat. So, a coat of white over the black was added to keep the light and heat out and provide a white reflective surface on the inside. ColorBond LVP proved to be great for use as a greenhouse paint.
Why Does ColorBond LVP Work Great on Polyurethane Panels?
ColorBond LVP offers a simpler solution to paint over polyurethane and without need for primer. ColorBond LVP is designed to bond to leather, vinyl, and plastic. Since polyurethane is a plastic it’s an ideal surface for ColorBond to adhere. The paint is durable, has a semigloss like sheen, and cleans up easily. ColorBond LVP is also user-friendly as it sprays on uniformly and has excellent coverage to reduce the number of coats that need to be applied. ColorBond LVP comes in an aerosol version and is also available in cans for application with a spray gun. ColorBond LVP looks great, and with 205 hues offered, there’s a wide choice of beautiful color options available.
How to Prepare Polyurethane Panels for Paint
- Clean the panels with ColorBond Prep Cleaner which removes dirt, grease, and other contaminants without leaving a residue that could interfere with paint adhesion.
- Scuff the urethane panels with fine grit sandpaper to provide an anchor surface pattern that’s best for adhesion of the ColorBond LVP.
How to Paint Over Polyurethane Panels with ColorBond LVP
- Apply a light mist coat of ColorBond LVP 12” from the surface.
- Multiple coats may be needed. Allow a 2-minute drying time between coats.
- ColorBond LVP bonds in 10 minutes.
“The finish is uniform, very durable and resists scratching very well” says Frank. “ColorBond LVP was perfect to paint a greenhouse . Also, the customer service was stellar. ColorBond was interested in helping and gave me all the knowledge I needed to be equipped for the job. I’m 100% satisfied and recommend ColorBond highly”.

Congratulations to Frank on a job well done and having the imagination to use ColorBond LVP refinisher as a greenhouse paint.
Of note, CB can be utilized on many types of plastics and can be used in the thermal forming of plastic.
