Hangar 9 UltraCote 10 Meter, Orange

Overview

 



Surface Preparation:
The covering task can just be as good as the finish of the surface it's applied over. In order for the covering to properly abide by a surface, the surface must {first|initially} be smooth and tidy. Sand the model utilizing a sanding block and gradually finer sandpaper, with the last sanding being made with 320 grit paper. Vacuum away all of the dust, as specks of dust under the covering will leave unpleasant bumps. Fill spaces and damages with a top quality filler. If utilizing light-colored UltraCote® (such as white or yellow), utilize a tan-colored filler that matches the wood color to avoid|avoid} the filler from revealing|revealing} through.

Pro Suggestion - Some professional contractors “raise the grain” then sand a 2nd time with 320 or 400 grit paper for the ultimate finish. After the model is sanded, utilize a damp cloth to clean down the model. Some modelers prefer to utilize a fine-mist squirt bottle filled with water to moisten the surface areas to be covered. As the surface dries, anchored wood fibers in the surface will “stand up.” When dry, sand the surface areas once again utilizing 320 or 400 grit paper. Raising the grain now and sanding it off will prevent the grain from raising later under the covering, creating a rough finish. Vacuum the model completely and prevent touching the model with oily hands.Your model is now check outy|prepared|all set} for covering!



Trim Film to Size:
Start by covering the bottom of one wing half. Utilizing scissors or sharp pastime knife, cut a piece of UltraCote® a couple of inches larger than had to cover the wing. Remove the backing (conserve for later) and position the covering with the adhesive (dull) side down, centered over the wing. Set the covering iron to the application temperature level|temperature level} of 220°F.

Pro Suggestion - If the iron you're utilizing does not display the actual temperature level, here is a suggestion that will ensure your iron is properly set.Water boils at 212°F. Enable your iron to heat up at a medium setting. When the iron reaches its supported temperature level, carefully put a couple of drops of water on the iron's surface. Change the temperature level until the water just starts to boil off. This method is surprisingly accurate and is typically within 10° (of the exact application temperature level of 220).


Adding Covering to Spar:
Tack the covering to the spar or the peak of the wing, utilizing your iron as shown (an iron sock is highly recommened). Carefully pull the covering toward the root and toward the idea, as you work the iron from the center of the spar to the root and idea of the wing. Press carefully with the iron, enabling the heat (not pressure) to activate the adhesive and bond the covering to the peak. Preferably, the covering will naturally lay flat versus the entire surface with a minimum of wrinkles.


Covering a Solid-Sheeted Wing:
If covering a solid-sheeted wing, work from the center of the spar outward to the tracking edge then to the cutting edge as shown, utilizing the iron at 220°F. If a wrinkle develops, the covering can be carefully lifted and reapplied.


Covering an Open-Structure Wing:
If covering an open-structure wing, work from the spar toward the tracking edge, carefully moving the iron (set at 220°) toward the tracking edge with the iron contacting two ribs. Utilizing your iron, adhere the covering to the staying ribs, working toward the idea and the root. Now finish the open structure leading edge, utilizing the very same method. If the leading edge is sheeted, then follow the technique noted above under “Covering a Solid-Sheeted Wing.”


Sealing the Edges:
With the iron set to 220°F, seal the leading and tracking edges. Utilizing a straight edge and a sharp #11 pastime knife, carefully trim the excess covering from the leading and tracking edge, enabling a minimum of a 1/4" overlap to wrap around the leading and tracking edge of the wing. Now seal the leading and tracking edges securely with the covering iron.


Wing Suggestion:
Depending on the quantity of the curvature of the wing idea, high heat (up to 350°F) may be had to shrink and extend the covering to eliminate all the wrinkles. Preset the iron to 300°F. Pull and extend the covering around the wing idea while using heat with the iron. Remember, UltraCote® can be carefully lifted and repositioned to help eliminate wrinkles. This feature is advantageous, specifically when covering greatly curved wing tips. Continue working, pulling, and warming the covering around the idea until the covering is past the center of the idea. It may be required to increase the temperature level of the iron to accomplish greater shrinking to eliminate all wrinkles. Trim the excess covering utilizing a #11 pastime knife, then reseal the covering on the wing tip.

Pro Suggestion - If sealing the covering in tight areas such as corners or fillets, utilizing the Hanger 9 ProTrim Sealing Tool is extremely handy and leads to a professional finish.


Covering the Top of the Wing:
Utilizing the backing from the wing panel that you just covered as a template, cut a piece of UltraCote® to be applied to the top of the wing. Make certain to cut a top panel, making sure that the adhesive is on the correct side. Apply the covering to the top of the wing utilizing the very same techniques as explained in actions 3 through 6. Make certain that the covering overlaps a minimum of a 1/4" when trimming the edges and securely seal the edges with the iron.


Shrinking the Covering:
Now it’s time to shrink the covering. With the iron set to 300°F, use heat utilizing the very same pattern used to use the covering beginning at the spar and working outward. It may be required to increase the temperature level to 320°F to get rid of stubborn wrinkles. Utilize the minimum quantity of heat required to tighten up the covering.

Pro Suggestion - Usage heat, not pressure, to shrink the covering taught. If pressure is applied, gouges can be pressed into the wood. Let heat, not pressure, do the work.
Alternate Method: A heat gun can also be used to shrink the covering. This works especially well over an open structure. It can also be used over a solid structure if a Wall mount 9 Covering Glove™ is used to carefully push the covering to the surface after heat is applied.


Covering Fuselages and Other Strong Surfaces:
The technique for covering fuselages and other basic flat surface areas corresponds covering a solid wing. Start with the bottom, then sides, and lastly the top. First, tack the center of the surface down utilizing an iron set to 220°F.Work outward from the center, bonding the covering to the surface. Trim and seal the edges. About 1/4" or more overlap is suggested when using the next piece of covering. Shrink the covering, utilizing the very same method as explained above.

Important: Even if you're experienced in using other brands of covering, it’s important to read the following instructions. UltraCote® includes a unique multi temperature managed adhesive and shrinking system that makes achieving professional covering outcomes easy.

Multi-Temperature Control System:
Comprehending the advantages of this system and how to utilize it will make covering with UltraCote® simple and assist to guarantee professional outcomes. When utilizing UltraCote®, there are three important temperature levels to be conscious of.

Application Tempature-220°F (100°C):
At 220°, the adhesive on UltraCote® ends up being active, enabling the covering to be connected to the model.While 220° will totally bond the covering to the model, it is well listed below the temperature level that triggers UltraCote® to shrink. This is exactly what's required when very first connecting covering to the model to prevent the covering from distorting.

Pro Suggestion - Numerous professional contractors mark this temperature level on their covering iron with a marker or striping tape for fast reference, as this temperature level is used regularly whenever putting on covering.

Shrink On-Set Temperature-300°F (134°C)
At 300°F, UltraCote® starts to shrink. This is called the Shrink On-Set point. After the covering is attached utilizing an iron set to 220°F, the next step is to shrink the covering. This preliminary shrinking is made with the iron set at 300°F.
Maximum Shrinkage Temperature-350°F (162°C)
At 350°F, UltraCote® reaches its maximum diminishing point. Raising the temperature level above this point will not trigger more shrinking.

The rate of shrinkage is not straight in percentage to the temperature level. The chart to the right demonstrates how the majority of the shrinking rate occurs in between 300°F and 330°F. At greater temperature levels UltraCote® continues to shrink but at a much slower rate. The tiniest quantity of shrinking occurs in between 340°F and 350°F. This is handy to remember when diminishing and tightening up covering.


Crucial:Once UltraCote® is diminished to a particular temperature level, a higher temperature level must be used to more shrink the covering. For instance, if the covering was diminished utilizing 320°F and wrinkles start to appear/reappear, it will be required to utilize over 320°F to accomplish more shrinkage.

Pro Suggestion - Always utilize the minimum heat required to remove wrinkles when tightening up the covering, hence enabling a lot of shrinkage/temperature range staying if it's required to more shrink the covering.



Handy Hints

Several Colors:
When using covering with a 2nd color, it’s important that the light color be applied first (under the dark color) to prevent the dark color from showing through. Where colors fulfill or at the edge of the covering, it is important to not overheat this location (over 300°F), as this will shrink and distort the straight edge.

Use a Sealing Iron Sock:
A covering sock positioned over the iron is highly suggested, as it usually prevents the surface of the iron from scratching. The sock soaks up heat and will need the user to work slower or to turn the warm up 10%. Practically all professional contractors utilize covering socks. Garage 9™ deals one of the very best that includes muslin on one side to prevent heat damage and soft cotton on the opposite for a soft, scratch-free finish.

Dryer is Better:
Wood naturally soaks up moisture.Wood designs in fact grow and shrink somewhat throughout various seasons. This can be experienced by traveling from the humid Midwest of the United State to the dry deserts of Las Vegas. After a couple of days in the desert, the model develops covering droops due to model shrinking. It is suggest that you cover the model in a dry climate if possible. Placing the model in a space with a dehumidifier for numerous days prior to covering the model may prevent the covering from sagging due to model shrinkage.

Painting:
UltraCote® will accept most types of polyurethane, epoxy, and automotive acrylic paints. It’s suggested that the surface be scuffed with 000 steel wool or Scotch® brilliant pads then completely cleaned up with acetone or thinner prior to painting. Design Dope or butyrate-based paint are not suitable with UltraCote®.

Bubbles and Acnes:
Sometimes the extreme heat from the sun can trigger bubbles and blemishes in the covering, specifically when utilizing dark colors. To remove these, heat the bubbled location utilizing a heat gun to expand the air under the covering, triggering the bubble to increase. Rapidly pop the bubble utilizing a needle then clean the location utilizing a cold, damp wash cloth. The damp wash cloth quickly cools the location, enabling the covering to re-adhere. It may take numerous attempt to totally remove the bubble/blemish, but this method works great.

Clean Up:
The adhesive can be gotten rid of from the iron or model utilizing acetone or a mild thinner.
