sand blast patterns on plexiglas - wind deflector for convertible car  -  protective plastic film
This instruction is about how to make a matte pattern that looks really cool for multiple purposes on plexiglass.
My example is the windshield of the Chrysler crossover.
It reduces the draft of the back and looks good.
To illustrate what you can do, I also joined LED ligting.
I certainly don't claim to have invented the concept, but since I can't find any good DIY guides in one place, I decided to share the whole process I came up.
I hope you like it, please leave a comment.
I would love to hear what you think of the tour guide.
This is what you need: 1. A good idea 2.
Organic Glass/acrylic glass.
Some parts of the guide may apply to Lexane, but I don't know. 3.
Enter the pressurized air 4.
Sand spray gun 5.
Basic household tools (
Pens, knives, scissors, etc. )
Cut the template into the desired shape.
If it should fit somewhere, make sure all the installation and adjustments have been made on the template.
Making changes to organic glass is much more difficult.
Get plexiglass/acrylic glass at a local home improvement shop or at a glass dealer.
My comment on not buying thin.
The thin plexi is very small, so it is difficult to form without braking.
I used 5mm of material.
It's usually a good idea to buy something bigger than you need.
Additional materials can be used to experiment and feel comfortable with the process.
Please note that the plexiglass is equipped with a plastic protective film.
Keep it as long as possible!
Acrylic glass is very sensitive.
Please note that it is easy to scratch even if the movie is on it. Handle gently!
Track the template to organic cellophane with an overhead pen or similar tool.
To support and relieve the pressure, put it on a thick piece of foam plastic.
This is important because the material is brittle and it is easy to crack.
Use a normal puzzle with a relatively fine tooth blade, but don't be too thin, because it will produce too much heat. Start cutting.
Press hard so that the saw does not rebound.
The difficult part is not to rush.
If you do, the blade will get too hot and the plastic will start to melt.
If you are as impatient as I am, you can cool the blade with pressurized air.
It's like a charm to me, and one more benefit is to blow all the sawdust away, thus reducing the risk of any sawdust being sawed down and in plastic (has happend).
Don't take a movie from protecive!
Use sandpaper to polish the edges to achieve the desired results.
If the edges start with rough paper, they gradually become thinner.
Remember not to rub too much in one place.
The plastic will begin to melt.
You can do this in one of two ways: 1. Be lazy -
Let someone make a template. I did.
It's actually an opposite sticker.
They keep what is usually wasted and remove what is usually a sticker.
I did it in a car parts store.
Let's say you have stickers.
Remove the protective film from the organic glass on one side.
Apply the sticker carefully.
Press hard around the edge.
Try to avoid bubbles.
They break when sandblasted.
In order to protect the material from any unnecessary blasting, shield it around the pattern as much as possible.
Two layers of normal masking tape work well. or 2.
Track/transfer the pattern to the protective film and cut it off using a surgical knife.
If you have a stable hand, it's not hard to be careful not to put the knife where it shouldn't be, or you will have scratches.
It is possible to remove or reduce scratches, but it is not easy.
This is a different tutorial anyway and has been described many times.
You finally got to the interesting part. Blast away!
Try to explode evenly.
Do it a bit at a time and check the template frequently so it still stays the same.
To check if the entire pattern is matte, use the light on the back.
Continue blasting until you are satisfied with the results or the template can no longer be used.
Stop when the edges are still good and define for the best results.
What to do here is obvious.
Remove all the masking film and protective film. Careful! Rememer -
It's easy to scratch.
Rinse in water to remove any residual sand or plastic debris.
Use a little soap if you want, but stay away from the strong detergent.
Dry with a clean and soft towel. Mount it.
The project is complete!
If you want to illuminate the pattern, please use the led strip at any edge.
