Shrinkage beginning begins at 300 degrees F.
Maximum shrinking is at 350 degrees F.

 



Surface Preparation:
The covering task can just be as excellent as the finish of the surface area it's used over. In order for the covering to appropriately stick to a surface, the surface area must {first|initially} be smooth and clean. Sand the design using 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 undesirable bumps. Fill gaps and dents with a premium filler. If using light-colored UltraCote® (such as white or yellow), utilize a tan-colored filler that matches the wood color to prevent the filler from revealing|revealing} through.

Pro Idea - Some expert builders “raise the grain” then sand a second time with 320 or 400 grit paper for the supreme finish. After the design is sanded, utilize a damp fabric to wipe down the design. Some modelers choose to utilize a fine-mist squirt bottle filled with water to dampen the surfaces to be covered. As the surface area dries, anchored wood fibers in the surface area will “stand.” When dry, sand the surfaces again using 320 or 400 grit paper. Raising the grain now and sanding it off will prevent the grain from raising later under the covering, developing a rough finish. Vacuum the design thoroughly and avoid touching the design with oily hands.Your design is now {ready|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 had to cover the wing. Eliminate the support (save for later) and place the covering with the adhesive (dull) side down, centered over the wing. Set the covering iron to the application temperature level of 220°F.

Pro Idea - If the iron you're using does not show the real temperature level, here is an idea that will ensure your iron is appropriately set.Water boils at 212°F. Enable your iron to warm up at a medium setting. When the iron reaches its supported temperature level, thoroughly pour a couple of drops of water on the iron's surface area. Adjust the temperature level till the water simply begins to boil off. This approach is remarkably accurate and is normally 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). Gently pull the covering towards the root and towards the tip, as you work the iron from the center of the spar to the root and tip of the wing. Press carefully with the iron, permitting the heat (not pressure) to trigger the adhesive and bond the covering to the peak. Preferably, the covering will naturally lay flat against the whole surface area 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 tracking 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 tracking edge, carefully sliding the iron (set at 220°) towards the tracking edge with the iron calling 2 ribs. Using your iron, adhere the covering to the remaining ribs, working toward the tip and the root. Now finish the open structure leading edge, using the exact same approach. If the leading edge is sheeted, then follow the technique listed above under “Covering a Solid-Sheeted Wing.”


Sealing the Edges:
With the iron set to 220°F, seal the leading and tracking edges. Using a straight edge and a sharp #11 hobby knife, thoroughly trim the excess covering from the leading and tracking edge, permitting 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 firmly with the covering iron.


Wing Idea:
Depending on the amount of the curvature of the wing tip, high heat (approximately 350°F) might be had to diminish and stretch the covering to eliminate all the wrinkles. Preset the iron to 300°F. Pull and stretch the covering around the wing tip while applying heat with the iron. Remember, UltraCote® can be thoroughly lifted and repositioned to assist eliminate wrinkles. This function is beneficial, especially when covering sharply curved wing pointers. Continue working, pulling, and warming the covering around the tip till the covering is past the center of the tip. It might be needed to increase the temperature level of the iron to accomplish higher shrinking to eliminate all wrinkles. Trim the excess covering using 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, using the Hanger 9 ProTrim Sealing Tool is extremely valuable and results in an expert finish.


Covering the Top of the Wing:
Using the support 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 leading panel, making certain that the adhesive is on the appropriate side. Apply the covering to the top of the wing using the exact same methods as described in steps 3 through 6. Be sure that the covering overlaps a minimum of a 1/4" when trimming the edges and firmly seal the edges with the iron.


Shrinking the Covering:
Now it’s time to diminish the covering. With the iron set to 300°F, apply heat using the exact same pattern utilized to apply the covering beginning at the spar and working outside. It might be needed to increase the temperature level to 320°F to obtain rid of stubborn wrinkles. Use the minimum amount of heat needed to tighten up the covering.

Pro Idea - Use heat, not pressure, to diminish the covering taught. If pressure is used, gouges can be pressed into the wood. Let heat, not pressure, do the work.
Alternate Approach: A heat weapon can also be utilized to diminish the covering. This works especially well over an open structure. It can also be utilized over a solid structure if a Wall mount 9 Covering Glove™ is utilized to carefully press the covering to the surface area after heat is used.


Covering Fuselages and Other Solid Surface areas:
The technique for covering fuselages and other easy flat surfaces is identical to covering a solid wing. Start with the bottom, then sides, and lastly the top. Initially, tack the center of the surface area down using an iron set to 220°F.Work outside from the center, bonding the covering to the surface area. 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 approach as described above.

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

Multi-Temperature Control System:
Comprehending the advantages of this system and ways to utilize it will make covering with UltraCote® easy 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, permitting the covering to be attached to the model.While 220° will totally bond the covering to the design, it is well listed below the temperature level that triggers UltraCote® to diminish. This is exactly what's required when first attaching covering to the design to prevent the covering from distorting.

Pro Idea - Lots of expert builders mark this temperature level on their covering iron with a marker or striping tape for quick reference, as this temperature level is utilized frequently whenever placing on covering.

Shrink On-Set Temperature-300°F (134°C)
At 300°F, UltraCote® begins to diminish. This is called the Shrink On-Set point. After the covering is connected using an iron set to 220°F, the next action is to diminish the covering. This initial shrinking is made with the iron set at 300°F.
Maximum Shrinking Temperature-350°F (162°C)
At 350°F, UltraCote® reaches its optimum shrinking point. Raising the temperature level above this point will not cause further shrinking.

The rate of shrinkage is not straight in proportion to the temperature level. The chart to the right shows how the majority of the shrinking rate takes place in between 300°F and 330°F. At higher temperatures UltraCote® continues to diminish but at a much slower rate. The smallest amount of shrinking takes place in between 340°F and 350°F. This is valuable to bear in mind when shrinking and tightening covering.


Important:When UltraCote® is diminished to a particular temperature level, a higher temperature level must be utilized to further diminish the covering. For example, if the covering was diminished using 320°F and wrinkles start to appear/reappear, it will be needed to utilize over 320°F to accomplish further shrinkage.

Pro Idea - Constantly utilize the minimum heat needed to remove wrinkles when tightening the covering, therefore permitting lots of shrinkage/temperature variety remaining if it's needed to further diminish the covering.



Useful Tips

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 satisfy or at the edge of the covering, it is essential to not overheat this location (over 300°F), as this will diminish and distort the straight edge.

Use a Sealing Iron Sock:
A covering sock placed over the iron is extremely recommended, as it typically prevents the surface area 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%. Almost all expert builders utilize covering socks. Hangar 9™ offers among the very best that features 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 takes in moisture.Wood designs in fact grow and diminish somewhat throughout different 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 shrinking. It is advise that you cover the design in a dry climate if possible. Placing the design in a space with a dehumidifier for a number of days before covering the design might prevent the covering from sagging due to design shrinkage.

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

Bubbles and Acnes:
Sometimes the extreme heat from the sun can cause bubbles and blemishes in the covering, especially when using dark colors. To remove these, heat the bubbled location using a heat weapon to broaden the air under the covering, causing the bubble to increase. Quickly pop the bubble using a needle then wipe the location using a cold, wet wash fabric. The wet wash fabric quickly cools the location, permitting the covering to re-adhere. It might take a number of aim to entirely remove the bubble/blemish, but this approach works great.

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