Surface area Preparation:
The covering job can just be as great as the finish of the surface it's applied over. In order for the covering to correctly adhere to a surface, the surface must initially|initially} be smooth and tidy. Sand the design using a sanding block and gradually finer sandpaper, with the last sanding being finished with 320 grit paper. Vacuum away all the dust, as specks of dust under the covering will leave unattractive bumps. Fill gaps and damages with a high-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 Pointer - Some expert home builders “raise the grain” then sand a 2nd time with 320 or 400 grit paper for the supreme finish. After the design is sanded, utilize a moist fabric to clean down the design. Some modelers choose to utilize a fine-mist squirt bottle filled with water to dampen the surface areas to be covered. As the surface dries, inserted wood fibers in the surface will “stand up.” 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 avoid touching the design with oily hands.Your design 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. Eliminate the support (conserve for later on) and position 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 Pointer - If the iron you're using does not display the real temperature level, here is a tip that will ensure your iron is correctly set.Water boils at 212°F. Permit your iron to heat up at a medium setting. When the iron reaches its supported temperature level, thoroughly pour a few drops of water on the iron's surface. Adjust the temperature level until the water simply starts to boil off. This approach is surprisingly accurate and is generally 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, using your iron as revealed (an iron sock is extremely recommened). Gently 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 carefully with the iron, permitting 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 outside to the routing edge then to the cutting edge as revealed, using the iron at 220°F. If a wrinkle develops, the covering can be thoroughly raised and reapplied.


Covering an Open-Structure Wing:
If covering an open-structure wing, work from the spar towards the routing edge, carefully moving the iron (set at 220°) towards the routing edge with the iron contacting 2 ribs. Utilizing your iron, adhere the covering to the remaining ribs, pursuing the idea 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 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 firmly with the covering iron.


Wing Pointer:
Depending on the quantity of the curvature of the wing idea, high heat (approximately 350°F) may be needed 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. Keep in mind, UltraCote® can be thoroughly raised and rearranged to help eliminate wrinkles. This function is advantageous, specifically when covering dramatically curved wing tips. Continue working, pulling, and heating up 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 attain greater shrinkage to eliminate all wrinkles. Trim the excess covering using a #11 hobby knife, then reseal the covering on the wing tip.

Pro Pointer - If sealing the covering in tight areas such as corners or fillets, using the Hanger 9 ProTrim Sealing Tool is very helpful and leads to an expert finish.


Covering the Top of the Wing:
Utilizing the support from the wing panel that you simply covered as a template, cut a piece of UltraCote® to be applied to the top of the wing. Make certain to cut a leading panel, making sure that the adhesive is on the correct side. Use the covering to the top of the wing using the exact same methods as described in steps 3 through 6. Make certain 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, use heat using the exact same pattern used to use the covering beginning at the spar and working outside. It may be required to increase the temperature level to 320°F to obtain rid of stubborn wrinkles. Use the minimum quantity of heat required to tighten up the covering.

Pro Pointer - 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 weapon can likewise be used to shrink the covering. This works particularly well over an open structure. It can likewise be used over a solid structure if a Hanger 9 Covering Glove™ is used 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 simple flat surface areas corresponds covering a solid wing. Start with the bottom, then sides, and finally the top. Initially, tack the center of the surface down using an iron set to 220°F.Work outside 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, using the exact same approach as described above.

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

Multi-Temperature Control System:
Understanding the advantages of this system and ways to utilize it will make covering with UltraCote® easy and help to make sure 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® ends up being active, permitting the covering to be connected to the model.While 220° will totally bond the covering to the design, it is well listed below the temperature level that causes UltraCote® to shrink. This is precisely what's needed when very first attaching covering to the design to avoid the covering from distorting.

Pro Pointer - 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 frequently 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 action is to shrink the covering. This preliminary 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 level above this point will not trigger additional 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 occurs in between 300°F and 330°F. At higher temperatures UltraCote® continues to shrink however at a much slower rate. The smallest quantity of shrinkage occurs in between 340°F and 350°F. This is helpful to keep in mind when diminishing and tightening up covering.


Crucial:When UltraCote® is shrunk to a specific temperature level, a greater temperature level must be used to additional shrink the covering. For instance, if the covering was shrunk using 320°F and wrinkles begin to appear/reappear, it will be required to utilize over 320°F to attain additional shrinkage.

Pro Pointer - Constantly utilize the minimum heat required to remove wrinkles when tightening up the covering, therefore permitting plenty of shrinkage/temperature variety remaining if it's required to additional shrink the covering.



Helpful 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 satisfy 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 put over the iron is extremely suggested, as it typically avoids 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%. Almost all expert home builders utilize covering socks. Hangar 9™ deals one of 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 soaks up moisture.Wood models in fact grow and shrink 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 few 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 room with a dehumidifier for several days before covering the design may avoid the covering from sagging due to design shrinkage.

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

Bubbles and Imperfections:
Sometimes the extreme heat from the sun can trigger bubbles and imperfections in the covering, specifically when using dark colors. To remove these, heat the bubbled location using a heat weapon to broaden the air under the covering, triggering the bubble to increase. Quickly pop the bubble using a needle then clean the location using a cold, damp wash fabric. The damp wash fabric rapidly cools the location, permitting the covering to re-adhere. It may take several aim to entirely remove the bubble/blemish, however this approach works great.

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