Yes, my caravan is the same... it's been outside through all this weather (and was down in warnanbool for there big wet last week at fun for kids). Just boring old silicon and butyl mastic used in mine though seeya, Shane L. |

Just out of interest, I know some of you have used mastic instead of sika... how long has it been since you used it and how have you found it so far? I have heard mastic only lasts about 5 years before it starts to crack and leak, and sika is great for 20 years (and more) but would be a b**ch to remove... I would like to know if theres a compromise between a removable sealant and long lasting at the same time.

I would like to know if theres a compromise between a removable sealant and long lasting at the same time. Hard to say "how long Mastic lasts", I understood 10 years. I used ribbon mastic on all my windows so removal would be easy. If the surface you are sealing with silicone/sika is not very clean then you may strike a leak, then removing the frame is a problem. As Shane suggests if done right then they should never leak again? Our van is out of the sun & under cover, I do not expect any problems soon with mastic. |

I had to replace the battery box in our modern recently. The mastic was exactly 10 years old and it was perfect still. Soft, pliable and sticky. I could have re-sealed the old box with it and it would have still been watertight I reckon.
I have to admit to being a bit of a convert, now. I used Z-Bond Ezycaulk butyl rubber to replace it, hopefully its as good.

Morning all
what about a paint on sealant for the underside of the plywood flooring as mine has split and is starting to peel,not bad for a van that is only 8 months old.
Cheers

I'd be going back to the manufacturer...
Assuming you can't, for some reason, I've sealed plywood on boats with west system epoxy resin. Its a runny liquid that you can brush on. Alternatively if the splits have movement in them then you'll probably need something flexible that will stretch, perhaps a paint-on waterproofing membrane, as used in bathrooms, roofs or swimming pools.

Gidday Micko
You need to go back to your dealer and speak to them before you do anything to your van. I assume you are covered by a warranty, you need to becareful what changes you do as they may impact your warranty.

Morning all what about a paint on sealant for the underside of the plywood flooring as mine has split and is starting to peel,not bad for a van that is only 8 months old. Cheers Micko Sorry to hear about that Micko, many of us here have plywood floor undersides more than 40 years old, mine looked almost brand new when i cleaned off the road grime, after buying it. I decided that unsealed must be good so did not bother sealing/ painting it. A few years later most dramas appear to be mosture contained. In your case i guess the wrong ply has been used! As anyone who has left out furnature etc has seen that split/ curl due to a lamminate glue that is not water resistant, or in the case of marine ply water proof. Deffo back to where you bought it. Re comments about seling it the drama is that moisture has already broken down laminates, so even if you went the penetrating epoxy route ( Everdure/ West number not remembered etc) a better than 50/50 chance of higher layer starting to become unstuck later, however the current bad bits will be nicely glued to their companion layer. Thinking about beating gravity should be a clue about sealing depth & even if you removed the floor or turned the caravan upside down the penetration will not go past 1mm, so if that ply floor is 12mm or more, a lot of grief still to be had! |

Thanks for all the input , our manufacturer is very dismissive of a very very long list of defects that continue to appear so don't know where this will finish but will keep pushing them for a result
Cheers

I had a viewer comment on one of my youtube Millard caravan resto videos and he said he worked building caravans in the past and highly recommends using Strip Caulking Tape. May try this on my next van. Example: www.caravanrvcamping.com.au/strip-caulkingCheers, |

Micko I have kust gone thru a "Warranty" experience, my issues were a little outside the box. You can get the appropriate response but you must be persistent, you must follow the warranty guidelines, as soon as you do any unauthorised repairs you will void your warranty and any chance for legal action against your dealer/supplier. They will string you along but you need to be persistent, document every communication you have with them. Accc will provide advice regarding your rights and actioms contact them link to ACCCPm me if you want more Bobt |

 I did the roof with Cartridges of butyl mastic lots of them and have the strip caulking to do windows door four seasons hatch and vents. I have a patches to do they are going to be done with a sika style adhesive as they will never have to be removed I hope but i should be right if I seal it correctly clean dry surfaces to start with.

One of the few good things to come out of cheap imports was the $1 shop hardware section selling superglue and sealants/ adhesives. Sellys had no choice but to at least sell something that half worked, rather than the extensive blame the handiman spiel, that lasted a few decades. Anyone ever seen Sellys, anything, used on a building site (non owner builder)? |

Remember the secret with slogans is the translation. *Trade Grade = Handimen may buy this twice. *Professional Grade = no trade folks go near that product! *Jobs and growth = we are selling more assets to overseas goverments who will use this investment for their citizens to work here on 457 visas! I am growing my karma portfolio for when i leave politics In 1976, where i worked, we had Dow Corning next door, we used used a lot of silicone, Selleys tried but never made the grade (medical for use internaly in humans) A development in batteries ( Lithium Gold) meant we could almost half the size of the implantable devices and our R&D crew (boffins) hooked into sino acrylic tech. This new fangled glue solved a lot of issues for weight, reliability and function. The one we used was made by Kodak! Later "that mob that works" tried to get the gig... well it stuck fingers together ok but during burn in testing, would have random fails from 2% to almost 30%. Shame as supply would be easier & cheaper but the stuff we used had a 100% pass rate, over the five years i kept in contact! (2 working there & 3 with mates/ managers, pre sell out to overseas as our goverment had a treasurer that was interested in chasing Aussie high tech manufacturing overseas for his wheat & wool PM!. |

So i wonder what the difference is between the 521 and 291? If both are adhesives I would prefer the 291 given its marine grade. As mentioned before, sikaflex has soooo many variations its just confusing. I re-read this thread and i really like the idea of your butyl rubber sealant in a cartridge that you used... ie its going to get into the valleys by squeezing out. Exactly the same as when i used the sika 291, but in this case it can be removed. How is it holding up? |

You will need to ask me in 20years time It's obviously still as good as the day it was assembled being only ... what 12months ago Being made with modern chemicals, I doubt it will dry out anywhere near as quickly as the stuff used in the 70's (especially when protected from the sun with foam seals). seeya, Shane L. |
