Spray Painting Plantation Shutters
image from here
This is why, a couple of years ago, while we had moved out of our house to have it renovated, I was on the lookout for some second hand ones on gumtree or ebay. Well I found some. Here they are. These,
The seller said, oh, you just need to spray paint them, you'll be fine. So off I went with them under my arm.
Two years later my husband is doing it, hooray!
Here are his top tips for successful spray painting:
Important: Safety First! Wear a proper facemask suitable for spray painting & make sure it seals well to your face without any gaps.
- Sand the surface with 120 grit paper.
- Hang the item using temporary screws and string so that contact points are minimised.
- Blow off dust with an airgun & wipe down all surfaces with microfiber wipe.
- Get some water based undercoat & mix it up, pour some into a spare tin or sealable container. Add 10% water & mix.
- Fill the airgun with the diluted paint. Set the air pressure to around 40psi. Adjust the settings by test spraying onto the side of an old cardboard box. Set the quantity of paint by adjusting the knob at the back of the gun. Set the ‘fan’ of the spray pattern by adjusting the knob near the nozzle. Its good to have a nice wide fan to make the coverage more even.
- Start spraying! Try to do the tricky areas first. Shutters have A LOT of little nooks & crannies & it took a few goes to work out what areas to do first… You should keep the gun moving as you spray to ensure you get a good coverage without any runs. It’s a balance between having a rough finish where the paint drops have not flowed together with each other and having too much paint which runs. Its not easy, but practise & learning as you go will get you there.
- Allow to dry for 2 hours or more. Empty the paint back into the container & clean the gun with plenty of water. You need to strip the gun down every time otherwise you will find that all the pigment settles into the nozzle and blocks it. Even if you think you know better & think ‘I know I’ll wrap the nozzle in a some moist rag to stop it drying out’. No, it won’t solve the settling in the nozzle problem…
- Repeat with the top coat. Use a water based paint suitable for timber.
You need to have plenty of reflecting light to see how the paint is going down as you are spraying. Use work lamps on either side of the work piece. You will need to position yourself so that you can see the light reflecting off the paint, its harder with white paint as its not so easy to see the reflection.
Cover anything in the garage /workshop with dropsheets. A few minutes spent doing this will save your prize possessions getting covered in spots of paint!
This is the aircompressor and below is the spray gun. The gun is gravity feed. Gravity feed guns need lower air pressure to achieve vacuum. Spraying with lower air pressure has the advantages of less overspray, less waste and greater control for the painter.
The gun is being held in a vice to keep the cup upright. The gun is not by any special maker. It is just a cheap one.
So here is the first one almost finished. I just love it so! They are going to look amazing when installed too. Can't wait.
