Shrinkage start starts at 300 degrees F.
Maximum shrinking is at 350 degrees F.

 



Surface Preparation:
The covering task can only be as good as the finish of the surface area it's used|used} over. In order for the covering to effectively abide by a surface area, the surface area should initially|initially} be smooth and clean. Sand the model using a sanding block and gradually finer sandpaper, with the last sanding being finished with 320 grit paper. Vacuum away all of the dust, as specks of dust under the covering will leave unpleasant bumps. Fill gaps and damages with a premium filler. If using light-colored UltraCote® (such as white or yellow), use a tan-colored filler that matches the wood color to prevent the filler from revealing|revealing} through.

Pro Suggestion - Some expert contractors “raise the grain” then sand a second time with 320 or 400 grit paper for the ultimate finish. After the model is sanded, use a wet fabric to wipe down the model. Some modelers choose to use a fine-mist squirt bottle filled with water to dampen the surfaces to be covered. As the surface area dries, inserted 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 on under the covering, developing a bumpy finish. Vacuum the model thoroughly and prevent touching the model with oily hands.Your model is now check outy|prepared|all set} for covering!



Trim Film to Size:
Start by covering the bottom of one wing half. Utilizing scissors or sharp pastime knife, cut a piece of UltraCote® a few inches larger than needed to cover the wing. Remove 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 Suggestion - If the iron you're using does not show the real temperature level, here is a suggestion that will ensure your iron is effectively set.Water boils at 212°F. Enable your iron to warm up at a medium setting. When the iron reaches its stabilized temperature level, carefully pour a few drops of water on the iron's surface area. Change the temperature level until the water simply starts to boil off. This technique is remarkably accurate and is normally within 10° (of the precise application temperature level of 220).


Tacking 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 toward the root and toward the tip, as you work the iron from the center of the spar to the root and tip of the wing. Press gently with the iron, allowing the heat (not pressure) to activate the adhesive and bond the covering to the peak. Ideally, the covering will naturally lay flat versus the entire 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 external to the tracking edge then to the cutting edge as shown, using the iron at 220°F. If a wrinkle establishes, the covering can be carefully lifted and reapplied.


Covering an Open-Structure Wing:
If covering an open-structure wing, work from the spar toward the tracking edge, gently sliding the iron (set at 220°) toward the tracking edge with the iron contacting two ribs. Utilizing your iron, adhere the covering to the staying ribs, pursuing the tip and the root. Now complete the open structure leading edge, using the exact same technique. 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 tracking edges. Utilizing a straight edge and a sharp #11 pastime knife, carefully cut the excess covering from the leading and tracking edge, allowing 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 Suggestion:
Depending upon the amount of the curvature of the wing tip, high heat (approximately 350°F) may be needed to shrink and stretch the covering to get rid of 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 carefully lifted and repositioned to assist get rid of wrinkles. This feature is advantageous, specifically when covering greatly curved wing pointers. Continue working, pulling, and warming the covering around the tip until the covering is past the center of the tip. It may be essential to increase the temperature level of the iron to accomplish higher shrinking to get rid of all wrinkles. Cut the excess covering using a #11 pastime knife, then reseal the covering on the wing tip.

Pro Suggestion - If sealing the covering in tight areas such as corners or fillets, using the Hanger 9 ProTrim Sealing Tool is really handy and results in a professional finish.


Covering the Top of the Wing:
Utilizing the support from the wing panel that you simply covered as a design template, cut a piece of UltraCote® to be applied to the top of the wing. Make certain to cut a top panel, making sure that the adhesive is on the appropriate side. Apply the covering to the top of the wing using the exact same techniques as described in actions 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 utilized to use the covering beginning at the spar and working external. It may be essential to increase the temperature level to 320°F to obtain rid of persistent wrinkles. Utilize the minimum amount of heat essential to tighten the covering.

Pro Suggestion - 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 Approach: A heat gun can also be utilized to shrink the covering. This works particularly well over an open structure. It can also be utilized over a solid structure if a Wall mount 9 Covering Glove™ is utilized to gently press the covering to the surface area after heat is applied.


Covering Fuselages and Other Solid Surface areas:
The technique for covering fuselages and other basic 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 external from the center, bonding the covering to the surface area. Cut and seal the edges. About 1/4" or more overlap is recommended when applying the next piece of covering. Diminish the covering, using the exact same technique as described above.

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

Multi-Temperature Control System:
Understanding the advantages of this system and the best ways to use it will make covering with UltraCote® simple and assist to ensure expert results. When using UltraCote®, there are 3 important temperature levels to be aware of.

Application Tempature-220°F (100°C):
At 220°, the adhesive on UltraCote® ends up being active, allowing the covering to be connected to the model.While 220° will fully bond the covering to the model, it is well listed below the temperature level that causes UltraCote® to shrink. This is precisely what's needed when very first connecting covering to the model to prevent the covering from distorting.

Pro Suggestion - Lots of expert contractors mark this temperature level on their covering iron with a marker or striping tape for quick reference, as this temperature level is utilized often whenever placing 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 preliminary shrinking is finished with the iron set at 300°F.
Maximum Shrinking Temperature-350°F (162°C)
At 350°F, UltraCote® reaches its maximum shrinking point. Raising the temperature level above this point will not cause more shrinking.

The rate of shrinkage is not straight in proportion to the temperature level. The chart to the right demonstrates how most of the shrinking rate takes place between 300°F and 330°F. At higher temperature levels UltraCote® continues to shrink but at a much slower rate. The smallest amount of shrinking takes place between 340°F and 350°F. This is handy to keep in mind when shrinking and tightening up covering.


Essential:Once UltraCote® is diminished to a particular temperature level, a greater temperature level should be utilized to more shrink the covering. For instance, if the covering was diminished using 320°F and wrinkles begin to appear/reappear, it will be essential to use over 320°F to accomplish more shrinkage.

Pro Suggestion - Constantly use the minimum heat essential to remove wrinkles when tightening up the covering, therefore allowing plenty of shrinkage/temperature variety staying if it's essential to more shrink the covering.



Practical Tips

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 satisfy or at the edge of the covering, it is necessary 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 positioned over the iron is extremely recommended, as it usually avoids the surface area of the iron from scratching. The sock absorbs heat and will need the user to work slower or to turn the warm up 10%. Practically all expert contractors use covering socks. Hangar 9™ offers one of the very best that features 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 absorbs moisture.Wood designs really 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 few days in the desert, the model establishes covering droops due to model shrinking. It is advise that you cover the model in a dry climate if possible. Placing the model in a space with a dehumidifier for several days before covering the model may prevent the covering from drooping due to model shrinkage.

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

Bubbles and Imperfections:
Sometimes the extreme heat from the sun can cause bubbles and blemishes in the covering, specifically when using dark colors. To remove these, heat the bubbled location using a heat gun to expand the air under the covering, triggering the bubble to rise. Quickly pop the bubble using a needle then wipe the location using a cold, damp wash fabric. The damp wash fabric quickly cools the location, allowing the covering to re-adhere. It may take several aim to entirely remove the bubble/blemish, but this technique works great.

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