Ами то точно това че е тънко е проблема в случая. По горе писах, това са лепила които трябва да изсъхнат на допир преди да слепиш двете повърхности. Ако едното беше плат как да е, през него може да се изпари разтворителя, но в твоя случай е кожа. Не го ли оставиш да изсъхне на допир няма да залепи както трябва, а ако е много рядко може и изобщо да не залепи.
ей тука ако имаш нерви са различните им лепила според приложението :

Directions for Use
When bonding wood veneers, success is dependent on many variables such as environmental conditions, bonding
process, type of base material, type of veneer, adhesive type and top coat finishing systems to name a few. It is the
user’s responsibility to thoroughly test any adhesive for its suitability in bonding wood veneers. It is also recommended
to follow the veneer manufacturers recommendation and industry guidelines.
Directions For Use:
1. Surface Preparation: Remove all dust, dirt, oil, grease, wax, loose paint, etc.
Wiping with solvent such as Methyl Ethyl Ketone (MEK) will aid in preparing the surface for bonding.*
2. Application Temperature: For best results the temperature of the adhesive and surfaces to be bonded should be at
least 65°F (18°C). If stored below 30°F (-1°C), warm-up to room temperature in a warm room only (do not exceed 120°F
(49°C) followed by thorough agitation).
3. Application: Stir or agitate well before using for optimum results. Apply 2.5 gms to 3.5 gms/ft.2 dry weight to each
surface. Unusually porous surfaces will require more adhesive.
4. Drying Time: The adhesive dries in about 10 minutes. High humidity will slow drying-high temperatures speed the
drying. This adhesive has a bonding range of approximately 30 minutes when applied to both bond surfaces under
conditions of 70°F (21°C) and 35% R.H. If the adhesive becomes too dry, apply another thin coat of adhesive to one
surface, allow to become slightly tacky, and bond.
Relative humidity above 50% can cause blushing (condensation of moisture on surface) and a false bond. To avoid this,
we recommend a force drying temperature of 180-220°F (82-104°C). Force drying will also help remove the solvent
more rapidly.
5. Assembly: Spacers, such as dowels or strips of laminate, may be used to help prevent premature adhesive/adhesive
contact and bonding prior to positioning. Slide out of the spacers and apply uniform pressure, working toward the edges.
A 3 in roller used with maximum body pressure should be used to help ensure adequate contact and bonding, especially
on edges. The use of a pinch roll is preferred for optimum performance. Bonded assemblies may be machined, trimmed,
etc. immediately after bonding.
6. Cleanup: Adhesive residue of 3M™ Neoprene High Performance Contact Adhesive 1357 and 1357-L may be removed
from exposed surfaces with solvents such as Methyl Ethyl Ketone (MEK), or 3M™ Citrus Base Industrial Cleaner.* For
flushing fluid lines use MEK.
*When using solvents, extinguish all ignition sources, including pilot lights, and follow the manufacturer’s precautions
and directions for use.
Като цяло това не е правено за платове и кожи като гледам. Също така понеже е много течно съхне доста бавно, 10 мин му дават. Като му гледам safety data sheet много вероятно е да реагира с пенопласта под кожата, пробвай първо някъде където не се вижда много дали няма да разтвори пенопласта, изглежда доста агресивно.
За твоя случай имат специални лепила, горе във видеото може да ги видиш, но и те рбаотят на същия принцип, пръскаш, чакаш да изсъхне и тогава слепяш.
