Posted this on RVOC, thought it might be useful to Funsters as well:
OK, as promised I am back from my site training at Sika UK and have a vast amount of information regarding sealants and adhesives for the Caravan/ Motorhome and Train carriage building market.
Unfortunately, as I am as thick as pea soup and the technician helping me with my enquiry was a boffin in the extreme, I tended to nod my head in agreement far too often when I should have said "Was that actually English you've just spoken"Link Removed
However, I did remember some of it and wrote most of it down. The technician was also kind enough to give me his direct line number if I have any questions in the future.
If you already understand sealants and adhesives then stop reading now. This is realy for those, like me who know nothing:
Sika adhesives are designed to be used with no other fixation device needed. Correct preparation of the substrate is therefore vital. The correct procedure and products needed for caravan/ RV work:
Pre treatment - Activator 205
Primers - Steel/ Aluminium - Primer 210
Plastic - Primer 206 G + P
Painted Substrates - Primer 209N
Interior Sealant - Sikaflex 221
Exterior Sealant - Sikaflex 521UV
Structural Adhesive - Sikaflex 252
The pre-treatment and primer phase are vital.
Unfortunately, only loctite manufacture products compatible with rubber coated substrates (Roof coatings etc)
I hope this helps. If you need any further help then PM me and I will contact the Sika technicianLink Removed
