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 correctly follow a surface, the surface should {first|initially} be smooth and clean. Sand the model utilizing a sanding block and gradually finer sandpaper, with the final 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 prevent the filler from {showing|revealing} through.

Pro Idea - Some professional builders “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 wet cloth to wipe down the model. Some modelers choose to utilize a fine-mist squirt bottle filled with water to moisten the surfaces to be covered. As the surface dries, anchored wood fibers in the surface will “stand.” When dry, sand the surfaces 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 bumpy finish. Vacuum the model completely and prevent touching the model with oily hands.Your model is now {ready|prepared|all set} for covering!



Trim Movie to Size:
Start by covering the bottom of one wing half. Utilizing scissors or sharp hobby knife, cut a piece of UltraCote® a few inches bigger than needed to cover the wing. Remove the support (conserve for later) and put 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 Idea - If the iron you're utilizing does not display the real temperature level, here is a pointer 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 pour a few drops of water on the iron's surface. Adjust the temperature level until the water just begins to boil off. This approach is surprisingly accurate and is generally within 10° (of the precise 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 revealed (an iron sock is extremely recommened). Carefully pull the covering toward the root and toward the suggestion, as you work the iron from the center of the spar to the root and suggestion of the wing. Press carefully with the iron, permitting the heat (not pressure) to trigger the adhesive and bond the covering to the peak. Ideally, 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 outside to the routing edge and then to the cutting edge as revealed, utilizing the iron at 220°F. If a wrinkle establishes, the covering can be thoroughly raised and reapplied.


Covering an Open-Structure Wing:
If covering an open-structure wing, work from the spar toward the routing edge, carefully sliding the iron (set at 220°) toward the routing edge with the iron calling 2 ribs. Utilizing your iron, adhere the covering to the staying ribs, working toward the suggestion and the root. Now finish the open structure leading edge, utilizing the very same approach. 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. Utilizing a straight edge and a sharp #11 hobby knife, thoroughly trim the excess covering from the leading and routing edge, permitting 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 securely with the covering iron.


Wing Idea:
Depending upon the amount of the curvature of the wing suggestion, high heat (as much as 350°F) might be needed to shrink and extend the covering to remove all the wrinkles. Preset the iron to 300°F. Pull and extend the covering around the wing suggestion while using heat with the iron. Keep in mind, UltraCote® can be thoroughly raised and rearranged to assist remove wrinkles. This feature is advantageous, especially when covering dramatically curved wing pointers. Continue working, pulling, and warming the covering around the suggestion until the covering is past the center of the suggestion. It might be essential to increase the temperature level of the iron to achieve higher shrinkage to remove all wrinkles. Cut the excess covering utilizing a #11 hobby knife, then reseal the covering on the wing tip.

Pro Idea - If sealing the covering in tight locations such as corners or fillets, utilizing the Hanger 9 ProTrim Sealing Tool is really valuable and results in a professional finish.


Covering the Top of the Wing:
Utilizing the support 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. Be sure to cut a leading panel, making certain that the adhesive is on the right side. Use the covering to the top of the wing utilizing the very same methods as explained in steps 3 through 6. Be sure that the covering overlaps a minimum of a 1/4" when cutting 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 utilized to use the covering beginning at the spar and working outside. It might be essential to increase the temperature level to 320°F to get rid of stubborn wrinkles. Use the minimum amount of heat essential to tighten up the covering.

Pro Idea - Use heat, not pressure, to shrink the covering taught. If pressure is applied, gouges can be pushed into the wood. Let heat, not pressure, do the work.
Alternate Technique: A heat weapon can also be utilized to shrink the covering. This works particularly well over an open structure. It can also be utilized over a strong structure if a Hanger 9 Covering Glove™ is utilized to carefully push the covering to the surface after heat is applied.


Covering Fuselages and Other Solid Surfaces:
The technique for covering fuselages and other easy flat surfaces corresponds covering a strong wing. Start with the bottom, then sides, and finally the top. First, tack the center of the surface down utilizing an iron set to 220°F.Work outside from the center, bonding the covering to the surface. Cut 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 approach as explained above.

Important: Even if you're experienced in using other brand names of covering, it’s important to read the following directions. UltraCote® includes a unique multi temperature controlled adhesive and shrinkage system that makes achieving professional covering results easy.

Multi-Temperature Control System:
Comprehending the advantages of this system and ways to utilize it will make covering with UltraCote® simple and assist to ensure professional results. When utilizing UltraCote®, there are three essential temperature levels to be mindful of.

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

Pro Idea - Many professional builders mark this temperature level on their covering iron with a marker or striping tape for fast recommendation, as this temperature level is utilized regularly whenever placing on covering.

Shrink On-Set Temperature-300°F (134°C)
At 300°F, UltraCote® begins to shrink. This is called the Shrink On-Set point. After the covering is connected utilizing an iron set to 220°F, the next action 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 optimum diminishing point. Raising the temperature level above this point will not cause further shrinkage.

The rate of shrinkage is not directly in percentage to the temperature level. The chart to the right demonstrates how most of the shrinkage rate happens between 300°F and 330°F. At greater temperature levels UltraCote® continues to shrink however at a much slower rate. The tiniest amount of shrinkage happens between 340°F and 350°F. This is valuable to keep in mind when diminishing and tightening up covering.


Important:As Soon As UltraCote® is diminished to a particular temperature level, a greater temperature level should be utilized to further shrink the covering. For example, if the covering was diminished utilizing 320°F and wrinkles begin to appear/reappear, it will be essential to utilize over 320°F to achieve further shrinkage.

Pro Idea - Constantly utilize the minimum heat essential to get rid of wrinkles when tightening up the covering, hence permitting lots of shrinkage/temperature variety staying if it's essential to further shrink the covering.



Handy Tips

Multiple 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 meet or at the edge of the covering, it is very important to not overheat this location (over 300°F), as this will shrink and misshape the straight edge.

Use a Sealing Iron Sock:
A covering sock placed over the iron is extremely suggested, as it usually prevents the surface of the iron from scratching. The sock takes in heat and will need the user to work slower or to turn the warm up 10%. Nearly all professional builders utilize covering socks. Hangar 9™ deals one of the best that includes muslin on one side to prevent 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 really 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 few days in the desert, the model establishes covering droops due to model shrinkage. It is suggest that you cover the model in a dry environment if possible. Placing the model in a room with a dehumidifier for a number of days before covering the model might prevent the covering from sagging due to model shrinkage.

Painting:
UltraCote® will accept most kinds of polyurethane, epoxy, and vehicle acrylic paints. It’s suggested that the surface be scuffed with 000 steel wool or Scotch® bright pads then completely cleaned with acetone or thinner before painting. Design Dope or butyrate-based paint are not compatible with UltraCote®.

Bubbles and Imperfections:
Sometimes the extreme heat from the sun can cause bubbles and acnes in the covering, especially when utilizing dark colors. To get rid of these, heat the bubbled location utilizing a heat weapon to expand the air under the covering, triggering the bubble to rise. Quickly pop the bubble utilizing a needle then wipe the location utilizing a cold, damp wash cloth. The damp wash cloth quickly cools the location, permitting the covering to re-adhere. It might take a number of attempt to completely get rid of the bubble/blemish, however this approach works great.

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