At The Spraying Team, we understand that giving your uPVC conservatory a fresh coat of paint can completely transform your space. Whether your white conservatory is looking tired or you've simply decided on a new colour, spray painting offers a cost-effective renovation option.
When a uPVC conservatory ages, the frames often become discoloured. The plastic surface may appear faded, especially with white conservatory structures that have been exposed to sunlight for years. Rather than replacing the entire structure, spray painting provides an affordable solution that extends the life of your conservatory.
Spray painting achieves a smooth finish that's difficult to reach with a paint brush or roller. The spray technique allows for even coverage across all surfaces, including those hard-to-reach areas of all the frames that would be challenging with traditional painting methods.
To spray paint your conservatory properly, gather these essential supplies:
The first and most important step is cleaning. Your uPVC conservatory frames must be completely free of dirt and grime before painting.
Start by washing all frames with sugar soap mixed with warm water. For stubborn areas, use a targeted cleaner. Pay special attention to corners where dirt collects. Use a damp cloth to wipe down all surfaces after cleaning, then allow them to dry completely. Paint adheres poorly to dirty surfaces, potentially leading to a poor finish later.
Examine the silicone around your conservatory glass. Any old silicone that's discoloured should be removed before painting.
Using a silicone removal tool, carefully cut away the old silicone. This task requires patience but is essential for good results. After removing the old silicone, clean the area to remove any residue.
You'll need to apply new silicone after the painting process is complete, so factor this into your project timeline.
Using fine-grit sandpaper, lightly sand all plastic surfaces that will be painted. The goal isn't to remove material but to create a slightly rough surface that helps the primer and paint adhere better.
After sanding, wipe down all surfaces with a clean, damp cloth to remove dust particles. Follow with isopropyl alcohol to ensure the surface is completely clean and free from any oils or residues.
This step is crucial for achieving a professional finish. Use masking tape to cover the edges of glass, as well as any hardware that won't be painted. Take your time with this step – careful masking will save significant clean-up work later.
Cover the floor and furniture with plastic sheeting to protect them from overspray. If your conservatory connects to your house, also mask the adjacent walls and windows to avoid accidental spray paint transfer.
A quality primer ensures the paint adheres properly to uPVC surfaces. Using your paint sprayer, apply a thin, even coat of primer to all the prepared surfaces.
Keep the sprayer moving at a consistent pace and distance to avoid drips. Aim for a light coat rather than trying to achieve full coverage in one go – multiple thin coats yield better results than one thick coat.
Allow the primer to dry completely according to the manufacturer's instructions before proceeding. This typically takes 1-2 hours but varies based on temperature and humidity.
Now for the main event – applying the colour coat. Set up your spray equipment according to guidelines, ensuring the paint is properly thinned if required.
Start from the roof of the conservatory and work downward, maintaining a consistent distance from the surface. Apply the paint in smooth, overlapping strokes to ensure even coverage without runs.
Most conservatories require at least two coats of paint for optimal coverage. Allow the first coat to dry completely before applying the second. Depending on the paint and conditions, this could take 2-4 hours.
After the second coat has dried, assess whether a third coat is needed. For lighter colours or significant colour changes, a third coat might be necessary.
Apply the final coat using the same technique as before, paying attention to any areas that look thin or uneven. This final coat provides the finished appearance, so take time to ensure perfect application for a good finish.
Once the final coat is completely dry (usually 24-48 hours), carefully remove all masking tape. Do this slowly and at an angle to prevent pulling off any paint.
If you removed old silicone earlier, now apply fresh silicone around the glass panels. Use quality exterior silicone sealant and apply it with steady, even pressure.
Weather plays a significant role in the success of your project. Ideal conditions are dry, calm days with moderate temperatures. Avoid painting on very hot days as the paint may dry too quickly, leading to brush marks or an uneven finish.
Similarly, avoid painting when it's cold, as the paint may not cure properly. High humidity can also affect drying times. If possible, check the weather forecast and plan your project for a period of settled weather.
Runs and drips are common issues when spray painting but can be avoided with proper technique. Keep the sprayer moving constantly and maintain a consistent distance from the surface. Apply multiple thin coats rather than one heavy coat.
If you notice runs forming, don't try to fix them while wet. Let the paint dry completely, then sand the affected area lightly before applying the next coat.
For even coverage, use systematic, overlapping strokes. Each pass should overlap the previous one by about 50% to ensure complete coverage. Also, keep the sprayer perpendicular to the surface you're painting as much as possible to avoid edges with thin coverage.
