How To Paint a Trampoline "String" Bed

Seems like an unusual article -- "How to Paint a Trampoline "String" Bed -- most people probably do not realize that this is part of the ongoing maintenance that needs to be done to your string bed to keep it in top working condition and help make it last a long time.

The Manufacturer recommends re-painting your String Bed every 6 – 12 months depending on usage. In extreme use cases -- such as sporting clubs -- repainting may be required as often as every 3 – 4 months.

If the trampoline is permanently sited outdoors, the frequency of repainting will need to be increased. Provided the correct repainting cycle is observed, the trampoline may be left outdoors indefinitely as the coated Terylene string is resistant to sunlight and rain.

PAINTING:

* Wash the bed with a VERY MILD soap and water solution using a soft bristle brush.
* Allow bed to completely dry before painting.
* Insert a pencil between each string intersection to straighten out the weave (even out the “boxes” created by the string intersections)
* Tape off red markings on mat both top and bottom.
* Spread drop cloths all around and underneath the bed – this is a very messy job!!
* Use a good quality acrylic paint.
* Paint should be applied while bed is mounted in frame.
* Apply paint with a roller applicator to BOTH top and bottom of the bed.
* Lightly tap bed with a piece of hose or a push broom to remove excess paint from weave.
* Quantity of paint needed -- 4 liter container should be sufficient for two coatings.

Trampoline String Beds are very expensive -- it only makes sense to upkeep and protect your investment. HAPPY JUMPING!!

How To Measure For A New Trampoline Bed

At some point in your coaching career, you will probably need to replace your current trampoline bed with a new one. If you are going to purchase a "String" Bed you have only two choices -- 6' x 12' and 7' x 14'. These dimensions refer to the size of the bed -- not the size of the trampoline frame. However, if you are going to purchase a Single Poly Black Bed (regular backyard style bed) or the new High Performance Black Poly Bed (HP Poly Bed) then you should do the following measurements to insure a correct fit.

1) Measure the INSIDE FRAME Dimensions (in inches) from spring hook attachment point to spring hook attachment point for the length and the width. (An example might be 101.5 inches wide by 176 inches long).
2) Remove one of your springs and measure the entire length from end to end including the hook. If you plan to purchase new springs, simply note the length of the new spring. (Examples would be 9 inch, 10 inch or 10.25 inch).
3) Count the number of spring hook attachment points that are welded on your trampoline frame. (An example might be 18 on the short ends and 37 on the long ends). In some cases, you will have a "zig-zag" wire that runs the length of your frame.

With this information, we can manufacture for you the correct size trampoline bed to EXACTLY fit your trampoline frame using the springs you have chosen. Often times, you will need a "Custom size" bed. For example, you might need a trampoline bed that is 6' 11" x 14' 2". Yes, a standard 7' x 14' would "fit" but having the exact size bed will make a big difference both in performance and longevity. The cost for "custom" is not much more than for standard and the lead time is just a few days longer.

It is a detail that you will be glad you took the time to do correctly.

Trampoline Spring Information

There are several trampoline springs on the market today, but you need to know the differences in order to make the correct decision when purchasing them. Most non-competitive or backyard trampolines utilize 9 in. springs and nearly all competitive trampolines utilize 10" or even 10 1/4 in. springs.

All trampolines springs have what is called a "Resting Stretch" and an "Active Stretch." The Resting Stretch is defined as the amount of stretch on the spring when it is attached to the trampoline frame and bed and nobody is jumping on it -- it is "at rest." The Active Stretch is defined as the length to which the spring could stretch when an average size person is "actively" jumping. See the chart below:

• 9 Inch Spring -- Resting Stretch of 11 - 12 in. -- Active Stretch of 14 - 15 in.
• 10 Inch Aussie "Jumbo" Spring -- Resting Stretch of 14 - 15 in. -- Active Stretch of 18 - 20 in.
• 10 1/4 Inch Aussie High Performance Spring -- Resting Stretch of 15 - 16 in. -- Active Stretch of 19 - 21 in.

As you can see, there is quite a difference. You will also note that depending on what spring size you choose has an impact on the actual size of the trampoline bed needed to correctly fit your trampoline frame. HAPPY JUMPING!!
