Surface Preparation:
The covering job can just be as great as the surface of the surface it's used|used} over. In order for the covering to appropriately follow a surface area, the surface must {first|initially} be smooth and clean. Sand the model utilizing a sanding block and gradually finer sandpaper, with the final sanding being finished with 320 grit paper. Vacuum away all the dust, as specks of dust under the covering will leave unpleasant bumps. Fill spaces and dents with a high-quality filler. If utilizing light-colored UltraCote® (such as white or yellow), use a tan-colored filler that matches the wood color to avoid the filler from revealing|revealing} through.

Pro Tip - Some expert builders “raise the grain” then sand a second time with 320 or 400 grit paper for the supreme surface. After the model is sanded, use a damp fabric to wipe down the model. Some modelers prefer to use 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 up.” When dry, sand the surface areas again utilizing 320 or 400 grit paper. Raising the grain now and sanding it off will avoid the grain from raising later under the covering, creating a bumpy surface. Vacuum the model completely and prevent touching the model with oily hands.Your model is now check outy|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 couple of inches larger than needed to cover the wing. Eliminate the support (conserve for later) and place the covering with the adhesive (dull) side down, centered over the wing. Set the covering iron to the application temperature of 220°F.

Pro Tip - If the iron you're utilizing does not show the actual temperature, here is an idea that will guarantee your iron is appropriately set.Water boils at 212°F. Permit your iron to warm up at a medium setting. When the iron reaches its supported temperature, thoroughly pour a couple of drops of water on the iron's surface. Change the temperature up until the water just begins to boil off. This approach is surprisingly accurate and is usually within 10° (of the specific application temperature of 220).


Tacking Covering to Spar:
Tack the covering to the spar or the high point of the wing, utilizing your iron as shown (an iron sock is extremely recommened). Carefully pull the covering toward the root and toward the pointer, as you work the iron from the center of the spar to the root and pointer of the wing. Press gently with the iron, permitting the heat (not pressure) to trigger the adhesive and bond the covering to the high point. Preferably, the covering will naturally lay flat against 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 after that to the cutting edge as shown, utilizing 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 toward the routing edge, gently moving 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 pointer and the root. Now complete the open structure leading edge, utilizing the very same approach. If the leading edge is sheeted, then follow the method 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 cut 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 Tip:
Depending on the quantity of the curvature of the wing pointer, 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 pointer while applying heat with the iron. Remember, UltraCote® can be thoroughly lifted and repositioned to assist eliminate wrinkles. This feature is beneficial, especially when covering greatly curved wing suggestions. Continue working, pulling, and warming the covering around the pointer up until the covering is past the center of the pointer. It may be necessary to increase the temperature of the iron to attain higher shrinking to eliminate all wrinkles. Cut the excess covering utilizing a #11 hobby knife, then reseal the covering on the wing tip.

Pro Tip - If sealing the covering in tight locations such as corners or fillets, utilizing the Hanger 9 ProTrim Sealing Tool is extremely helpful and leads to an expert surface.


Covering the Top of the Wing:
Utilizing the support from the wing panel that you just covered as a design template, cut a piece of UltraCote® to be used to the top of the wing. Make sure to cut a top panel, ensuring that the adhesive is on the right side. Use the covering to the top of the wing utilizing the very same methods as described in actions 3 through 6. Make 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, apply heat utilizing the very same pattern used to apply the covering starting at the spar and working outside. It may be necessary to increase the temperature to 320°F to obtain rid of persistent wrinkles. Use the minimum quantity of heat necessary to tighten the covering.

Pro Tip - Usage 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 Approach: A heat weapon can likewise be used to shrink the covering. This works especially well over an open structure. It can likewise be used over a strong structure if a Hanger 9 Covering Glove™ is used to gently push the covering to the surface after heat is used.


Covering Fuselages and Other Strong Surfaces:
The method for covering fuselages and other easy flat surface areas corresponds covering a strong 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 outside from the center, bonding the covering to the surface. Cut and seal the edges. About 1/4" or more overlap is recommended when applying the next piece of covering. Diminish the covering, utilizing the very same approach as described above.

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

Multi-Temperature Control System:
Comprehending the benefits of this system and ways to use it will make covering with UltraCote® easy and assist to ensure expert outcomes. When utilizing UltraCote®, there are three important temperature levels to be aware 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 listed below the temperature that causes UltraCote® to shrink. This is exactly what's required when first attaching covering to the model to avoid the covering from distorting.

Pro Tip - Lots of expert builders mark this temperature on their covering iron with a marker or striping tape for fast reference, as this temperature is used often whenever putting 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 step is to shrink the covering. This initial shrinking is finished 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 above this point will not cause additional shrinking.

The rate of shrinkage is not directly in percentage to the temperature. The chart to the right shows how the majority of the shrinking rate happens in between 300°F and 330°F. At higher temperature levels UltraCote® continues to shrink but at a much slower rate. The smallest quantity of shrinking happens in between 340°F and 350°F. This is helpful to bear in mind when diminishing and tightening covering.


Crucial:When UltraCote® is diminished to a particular temperature, a higher temperature must be used to additional shrink the covering. For instance, if the covering was diminished utilizing 320°F and wrinkles start to appear/reappear, it will be necessary to use over 320°F to attain additional shrinkage.

Pro Tip - Constantly use the minimum heat necessary to eliminate wrinkles when tightening the covering, therefore permitting a lot of shrinkage/temperature range staying if it's necessary to additional shrink the covering.



Handy Hints

Numerous 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 meet or at the edge of the covering, it is essential 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 placed over the iron is extremely recommended, as it usually avoids the surface of the iron from scratching. The sock absorbs heat and will require the user to work slower or to turn the heat up 10%. Almost all expert builders use covering socks. Hangar 9™ deals one of the very 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 absorbs moisture.Wood models actually grow and shrink slightly throughout different seasons. This can be experienced by taking a trip from the damp Midwest of the United State to the dry deserts of Las Vegas. After a couple of days in the desert, the model develops covering sags due to model shrinking. It is recommend that you cover the model in a dry environment if possible. Putting the model in a space with a dehumidifier for numerous days prior to covering the model may avoid the covering from drooping due to model shrinkage.

Painting:
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® 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 Blemishes:
Periodically the extreme heat from the sun can cause bubbles and blemishes in the covering, especially when utilizing dark colors. To eliminate these, heat the bubbled area utilizing a heat weapon to broaden the air under the covering, causing the bubble to rise. Rapidly pop the bubble utilizing a needle then wipe the area utilizing a cold, wet wash fabric. The wet wash fabric rapidly cools the area, permitting the covering to re-adhere. It may take numerous tries to completely eliminate the bubble/blemish, but this approach works great.

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