The chassis on our Olympic Riviera is in need of a bit of TLC. It needs a good clean up and then painted. Unlike the earlier Olympics the chassis is not possible to remove on the later ones due to the ply floor glued directly to the chassis. As I don't want to lay on my back for days cleaning it with a wire brush I was thinking garnet or glass blasting would be a better option, plus a better job. Has anyone had this type of blasting done. If so did they use garnet or glass, and how high off the ground does it need to to be?
Thanks
Warren

We used garnet as it does not clog the gaps, also the blaster can recycle the glass for another use by laying a tarp under the van. A wire brush cannot get into 90 degree corners. Our frame was then epoxy sprayed, still as good as the day it was done. We also did the wheels & insides of the hub caps. The wheels were removed & the van placed on jacks, I believe the contractor now has a drive over pit.   Before:  The cost of $700 for blasting & painting was worth it to me, also gave us piece of mind that the chassis was solid. We didn't seal the floor as a senior member here suggested moisture should be allowed to dry out. |

Thanks Mustang, it is good to know it is doable. Just have get the caravan high enough and find a sandblaster who is prepared to lay on his back to do the job.

We should keep track of floors that the underside is sealed V the original open grain, to myth bust the reality. So far the only rotted ones seem to have had the underply painted at some stage, from my brief time exploring the issue.
+1000 about paying to have someone do the upside own work!

I've had 3 vans (16ft & 13ft Viscounts & 11ft Millard) sandblasted & primed & top coated by a regional Vic contractor for around $400 - $500 each. Never saw him in operation but I believe he's got a platform set up that he winches vehicles up onto. As for painting the underside of ply, if it's breathable oil based paint it may be fine but probably be best to avoid acrylic house paint as it's know to cause moisture lock and rot issues.... forum.woodenboat.com/archive/index.php/t-92105.html |

When i first crawled under mine & dusted off some road grime i saw perfect timber, i figured that 1975 - 2014 it was not a priority to paint against gravity!  Edit, i knew i should not have clicked on that WB link!  As a side note to the guy dissing industrial paints... In 1972 mate & i painted his family exterior home with *sub latex acrylic, his Dad chose it as it was used to seal flat top roofs on office blocks, he was a building caretaker & got a cheap deal on 80 litres to paint the large 5 bedroom exterior, of a 1920s house with tall ceilings. ( about 4 metres + from garden to eaves) This miracle thing to be used against the advice of neighbours & the local hardware store bloke who still moaned about lead free paint turned out to be amazing! We just hosed & stiff broomed the old flakey paint and as sections dried we started painting ( the coating rep said just whack it on!) Various cracks that the Dad said ignore we discovered that the semi dry gummy stuff on the roller tray edges could be rolled & inserted into the cracks as a filler #win, it would shrink a bit as it dried so a few days later just squeezed in some more if required. Many areas of the old coal stucco had fallen off so again ignoring his Dad to not worry about it we started making balls of gummy paint to match the missing lumps, areas of render that had fallen out we filled with a slurry of sand & coating then added gummy balls when flush = more #wins. Testimony was in 2008 a quick cheap top coat was thrown over what we did, pre sale, as the algercide had prevented any mould on the South side & no new cracks or bits had fallen off, after all those years. *Now known as Premium Elastomeric Water-Based Acrylic Latex Paint |
