Garage 9 UltraCote® is a high tech polyester covering that features a unique multi temperature-controlled adhesive and shrinkage system, making it versatile and simple to apply. A trademarked polymerizing process completely merges the color to the polyester movie covering, removing the possibilities of color-layer separation and allows rearranging the covering on your design. UltraCote's distinct capability to both shrink and stretch make it exceptional to other coverings for walking around tight curves and wingtips.
Temp ranges are as follows:

Adhesion to wood starts at 200 to 220 degrees F.
Shrinkage onset starts at 300 degrees F.
Optimum shrinkage is at 350 degrees F.


Surface area Preparation:
The covering task can just be as great as the finish of the surface it's used|used} over. In order for the covering to correctly comply with a surface area, the surface needs to initially|initially} be smooth and clean. Sand the design using a sanding block and gradually finer sandpaper, with the final sanding being performed with 320 grit paper. Vacuum away all of the dust, as specks of dust under the covering will leave unpleasant bumps. Fill gaps and dents with a top quality filler. If using 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 Tip - Some expert home builders “raise the grain” then sand a second time with 320 or 400 grit paper for the ultimate finish. After the design is sanded, utilize a wet cloth to clean down the design. Some modelers choose to utilize a fine-mist squirt bottle filled with water to moisten the surface areas to be covered. As the surface dries, imbedded wood fibers in the surface will “stand.” When dry, sand the surface areas again using 320 or 400 grit paper. Raising the grain now and sanding it off will avoid the grain from raising later on under the covering, creating a rough finish. Vacuum the design thoroughly and prevent touching the design with oily hands.Your design is now check outy|prepared|all set} for covering!

Trim Film to Size:
Start by covering the bottom of one wing half. Using scissors or sharp hobby knife, cut a piece of UltraCote® a couple of inches bigger than needed to cover the wing. Get rid of the backing (conserve for later on) and place the covering with the adhesive (dull) side down, focused over the wing. Set the covering iron to the application temperature level of 220°F.

Pro Tip - If the iron you're using does not show the actual temperature level, here is an idea that will ensure your iron is correctly set.Water boils at 212°F. Allow your iron to heat up at a medium setting. When the iron reaches its stabilized temperature level, thoroughly put a couple of drops of water on the iron's surface. Change the temperature level until the water simply starts to boil off. This method is surprisingly accurate and is generally within 10° (of the specific application temperature level of 220).

Adding Covering to Spar:
Tack the covering to the spar or the peak of the wing, using your iron as shown (an iron sock is extremely recommened). Carefully pull the covering towards the root and towards the idea, as you work the iron from the center of the spar to the root and idea of the wing. Press gently 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 whole surface with a minimum of wrinkles.

Covering a Solid-Sheeted Wing:
If covering a solid-sheeted wing, work from the center of the spar external to the routing edge and then to the leading edge as shown, using the iron at 220°F. If a wrinkle develops, the covering can be thoroughly lifted and reapplied.

Covering an Open-Structure Wing:
If covering an open-structure wing, work from the spar towards the routing edge, gently sliding the iron (set at 220°) towards the routing edge with the iron calling two ribs. Using your iron, adhere the covering to the staying ribs, working toward the idea and the root. Now complete the open structure leading edge, using the exact 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 routing edges. Using a straight edge and a sharp #11 hobby knife, thoroughly trim the excess covering from the leading and routing edge, enabling a minimum of a 1/4" overlap to twist around the leading and routing edge of the wing. Now seal the leading and routing edges firmly with the covering iron.

Wing Tip:
Depending on the amount of the curvature of the wing idea, high heat (as much as 350°F) may be needed to shrink and stretch the covering to eliminate all the wrinkles. Preset the iron to 300°F. Pull and stretch the covering around the wing idea while applying heat with the iron. Remember, UltraCote® can be thoroughly lifted and repositioned to assist eliminate wrinkles. This function is useful, particularly when covering sharply curved wing ideas. 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 higher shrinkage to eliminate all wrinkles. Trim the excess covering using a #11 hobby knife, then reseal the covering on the wing tip.

Pro Tip - If sealing the covering in tight areas such as corners or fillets, using the Wall mount 9 ProTrim Sealing Tool is very valuable and results in a professional finish.

Covering the Top of the Wing:
Using the backing from the wing panel that you simply covered as a design template, cut a piece of UltraCote® to be used to the top of the wing. Be sure to cut a top panel, ensuring that the adhesive is on the proper side. Use the covering to the top of the wing using the exact same methods as explained in actions 3 through 6. Be sure that the covering overlaps a minimum of a 1/4" when cutting the edges and firmly seal the edges with the iron.

Shrinking the Covering:
Now it’s time to shrink the covering. With the iron set to 300°F, apply heat using the exact same pattern used to apply the covering beginning at the spar and working external. It may be required to increase the temperature level to 320°F to obtain rid of stubborn wrinkles. Utilize the minimum amount of heat required to tighten up the covering.

Pro Tip - Use heat, not pressure, to shrink the covering taught. If pressure is used, gouges can be pushed into the wood. Let heat, not pressure, do the work.
Alternate Technique: 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 Hanger 9 Covering Glove™ is used to gently press the covering to the surface after heat is used.

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

Important: Even if you're experienced in applying other brand names of covering, it’s important to read the following guidelines. UltraCote® incorporates a unique multi temperature controlled adhesive and shrinkage system that makes attaining expert covering outcomes easy.

Multi-Temperature Control System:
Understanding the benefits of this system and how to utilize it will make covering with UltraCote® simple and help to ensure expert outcomes. When using UltraCote®, there are three crucial temperatures to be aware of.

Application Tempature-220°F (100°C):
At 220°, the adhesive on UltraCote® becomes active, enabling the covering to be attached to the model.While 220° will completely bond the covering to the design, it is well listed below the temperature level that causes UltraCote® to shrink. This is precisely what's required when first connecting covering to the design to avoid the covering from distorting.

Pro Tip - Numerous expert home builders mark this temperature level on their covering iron with a marker or striping tape for quick recommendation, 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 using an iron set to 220°F, the next step is to shrink the covering. This initial shrinking is performed with the iron set at 300°F.
Maximum Shrinkage Temperature-350°F (162°C)
At 350°F, UltraCote® reaches its maximum shrinking point. Raising the temperature level above this point will not trigger more shrinkage.

The rate of shrinkage is not directly in proportion to the temperature level. The chart to the right shows how the majority of the shrinkage rate happens in between 300°F and 330°F. At higher temperatures UltraCote® continues to shrink however at a much slower rate. The tiniest amount of shrinkage happens in between 340°F and 350°F. This is valuable to remember when shrinking and tightening up covering.

Essential:Once UltraCote® is diminished to a specific temperature level, a higher temperature level needs to be used to more shrink the covering. For instance, if the covering was diminished using 320°F and wrinkles begin to appear/reappear, it will be required to utilize over 320°F to accomplish more shrinkage.

Pro Tip - Always utilize the minimum heat required to get rid of wrinkles when tightening up the covering, thus enabling plenty of shrinkage/temperature range staying if it's required to more shrink the covering.

Valuable Hints

Several Colors:
When applying covering with a second 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 very important to not overheat this area (over 300°F), as this will shrink and distort the straight edge.

Use a Sealing Iron Sock:
A covering sock put over the iron is extremely recommended, as it typically avoids the surface of the iron from scratching. The sock takes in heat and will need the user to work slower or to turn the heat up 10%. Practically all expert home builders utilize covering socks. Garage 9™ deals among the best that features muslin on one side to avoid heat damage and soft cotton on the other side for a soft, scratch-free finish.

Dryer is Better:
Wood naturally takes in moisture.Wood models actually grow and shrink slightly 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 design develops covering droops due to design shrinkage. It is suggest that you cover the design in a dry climate if possible. Placing the design in a space with a dehumidifier for numerous days prior to covering the design may avoid the covering from drooping due to design shrinkage.

UltraCote® will accept most kinds of polyurethane, epoxy, and automotive acrylic paints. It’s recommended that the surface be scuffed with 000 steel wool or Scotch® bright pads then thoroughly cleaned with acetone or thinner prior to painting. Model Dope or butyrate-based paint are not suitable with UltraCote®.

Bubbles and Blemishes:
Sometimes the intense heat from the sun can trigger bubbles and imperfections in the covering, particularly when using dark colors. To get rid of these, heat the bubbled area using a heat gun to broaden the air under the covering, causing the bubble to rise. Rapidly pop the bubble using a needle then clean the area using a cold, wet wash cloth. The wet wash cloth quickly cools the area, enabling the covering to re-adhere. It may take numerous attempt to completely get rid of the bubble/blemish, however this method works great.

Clean Up:
The adhesive can be eliminated from the iron or design using acetone or a mild thinner.
