Guidance for Fabric Covering Lay-Out
Recommended job for two or three persons (to complete the covering
process).
Description.
We recommend you use the Ceconite system for covering your Foxbat.
Other systems may be suitable if you have a preference. However, in our
experience the Ceconite team provide a very high quality product and are
extremely helpful. They are also familiar with the Foxbat’s covering
requirements and provide a kit of materials (with Foxbat specific
instructions) that is likely to incur the minimum of waste.
There is nothing particularly unusual about covering a Foxbat, it’s basically
a standard “fabric over aluminium ribs” technique, and almost everything
relevant to covering a Foxbat can be found in Ceconite’s excellent
Instruction Manual. No respiratory apparatus is required when applying the
adhesive although skin contact should be avoided. Full instructions for use
are provided with our covering kit.
Fabric Covering Process
As a general guide, here are some basic instructions for covering the
Foxbat – however, refer to the Ceconite Manual for full details.
1. Scour and degrease aluminium-cement-fabric contact points. Use scratch
pads and fresh cloths or paper wipes from paint shop to avoid
contamination with silicone.
2. Brush neat cement onto contact points (two coats).
3. Lay pre-cut Ceconite fabric on job so that it lies naturally without
wrinkling or excessive sagging. There is no need to stretch the fabric
tight at this stage. Ample fabric is supplied with your kit but take note
of the cut pattern illustrated in the build manual.
4. Brush a 9:1 MEK/cement mixture through fabric at contact points around
the perimeter of job (but not the inner ribs at this time). This MEK mix
will soften the previously applied cement (see #2 above). Use a light
rubbing action with a finger to help draw the cement up through the
fabric weave. Allow the cement to dry.
