When you’re buying Parking Lot Stencils, there are (3) things to look for:
1) The material that the stencil is made from.
2) The thickness of the stencil itself.
3) The overall dimensions that the stencil offers. And I mean all of them, not just “overall height”.
So first, referring to #1;
Parking Lot Stencil Material.
I’ve seen parking lot stencils being advertised as “made from quality”, and then there’s this fancy word for cardboard.
I’ve also seen them made from “counter top” material.
The best material is Low Density Polyethylene Plastic, ( LDPE )…not High Density Polyethylene, ( HDPE ). It’s the favorite material among parking lot striping companies. Here’s why;
A) It’s strong, unlike cardboard. It’s more flexible, unlike counter top material.
B) It’s also too easy to clean. Spray the stencil. You’ll have a bit of “over spray” on the stencil itself. Let it dry. Then, bend the flexible, LDPE and the dried over spray pops off.

Or you can peel it off and it looks like a giant potato chip. Now your stencil is “like new again.”
If you spray a cardboard stencil, the over spray soaks in. You cannot clean it easily and then hope to re-use it for years to come.
If you spray a stencil made from some type of counter top material, two things may occur.
1) It’s too rigid to bend. If you do try to bend it, be ready for it to break.
2) If the counter top material is rough, instead of smooth, the over spray will grip it tightly and won’t let go. You cannot clean it back to “like new again”. After a while the over spray will build up and effect the quality of your work.
Bottom line, buy LDPE. It’s more flexible than HDPE. It’ll lay to the contour of your parking lot. It’ll last. It’s too easy to clean…etc…etc.
NEXT; Parking Lot Stencil Thickness.
I’ve seen 10 Mil thicknesses and 30 Mil thicknesses. I’ve seen 60 Mil and 125 Mil.
10 Mil is about (3) pieces of paper, thick. 30 Mil is about (10) pieces of paper, thick. There are a few things to consider, here.
1) If it’s too thin, like 10 Mil, it may not stay where you need it to. ( I hope the wind doesn’t blow! )
2) When the actual paint hits the stencil, be prepared for the stencil to “flutter” and / or simply move. It’s not heavy enough to do the work. Also, these aren’t heavy enough to lay completely flat. If they’re “wavy” at all…again…they do not possess the weight needed to simply lay flat. Paint will spray under the areas that are above the pavement and affect the quality of your work.
3) If you have to slide a “thin” material stencil out from under another stencil…the small “bridges” that hold the letters or symbols to the surrounding plastic will eventually snag onto something and tear. This makes for more trouble. Be careful.
The best (2) thicknesses are 60 Mil and 125 Mil.
60 Mil parking lot stencils are for occasional use. Schools that stripe or paint their own stencils can use these. A part time parking lot striping company or the maintenance department of a shopping center or hospital will find that these are fine. Just take care of them.
125 Mil is for the professional parking lot striping company. Let the over spray dry. Peel it off. The bridges are tough. This thickness will last, seemingly forever.
NEXT…Parking Lot Stencil “Overall Dimensions”.
This is actually quite simple. There are two things involved. One is the overall height. The other is the height, width and brush stroke of the individual letters. Now I’ll say it backwards; look for the height, width and brush stroke of each letter. THEN there’s theoverall height which will tell you the edged distances.
Let’s start with the overall height.
The first thing you’ll almost always notice is an advertisement for the “overall height”.
When you see overall height, it’s referring to the total height of the piece of plastic that the lettering or symbol is cut from.
Here’s what that means; let’s say the stencil is a NO PARKING stencil with 12″ tall letters. Let’s say the “overall height” is 16″. That means there’s only 2″ of plastic above the top of the lettering and 2″ of plastic below the bottom of the lettering. Again; if you add a 2″ edge distance on top, with a 12″ lettering and another 2″ edge distance along the bottom, you’ll arrive at the 16″ overall height.
I like an 18″ overall height. Here’s why; it’s not just about over spray protection, it’s about strength.
1) If you’re not too confident about spraying the stencil, a 2″ edge distance is scary.
A 3″ edge distance isn’t as scary. ( On a 12″ NO PARKING stencil the overall height would be 18″, not 16″. )
2) If you want these to last any amount of time, a 3″ edge distance offers much more strength than only having a 2″ edge distance.
NEXT; the actual height of the lettering is probably going to be decided upon by you. Common parking lot stencils have 12″ and 24″ tall lettering. However, again, this is up to you.
NEXT; The Width of each letter is important. I like anywhere from 8″ to 9″ wide for a 12″ tall letter. ( The “W” is simply wider than the “V”. ) I also like a 12″ width for a 24″ tall letter, such as STOP. It’s about having a balanced look and taking up the given space so the stencil can best do it’s job.
LAST; The Brush Stroke. Pretend you’re painting the letter using a paint brush. How wide is the paint brush? Is it 1″ wide? Is it 4″ wide? That dimension is the called the brush stroke. On a 12″ tall letter make sure your brush stroke is at least 2″ wide. On a 24″ tall letter, I like a 3″ to 4″ brush stroke. It needs to be seen. A “narrow” STOP may not work as well as a 24″ tall, 12″ wide, STOP with a 4″ brush stroke.
Bottom line; if you’re shopping for Parking Lot Stencils, look for three things. ( Ok, maybe four things. )
