I had a little water damage to my track over the weekend. Some rain water ran along an over head heat pipe and landed on my track in a few areas. It didn't affect the painted areas but it got into the slot in a few areas and caused some swelling. I know I'll probably have to pull up the tape sand it down repaint and retape in a few areas. On the small chance that it might dry and shrink back I figured I would ask. If I do have to fix it though I think I'll take some pics and post a how to repair water damage thread. Maybe make the repaired areas a different color so they look like they were repaired by a 1/32nd road crew LOL
once MDF gets wet, it is ruined. it becomes a host for mold, will no longer hold fasteners well, & becomes structurally weak. in its application in our hobby, once you have machined it, it should be painted on all exposed surfaces to prevent it from absorbing moisture.
Yeah thats what I thought I have two small areas where a little water tracked across the painted road and found the slot. The other area the water found where two boards meet and got between them . Both areas are about a half inch wide and three or four inches long. I don't think it swelled more than a 16th of an inch high but when the cars race over the areas you can see them jump. I'm hoping this weekend I can pull the tape up, sand it down, repaint and and re tape the damage.
While routing one of my tracks I accidently knocked over a extra large Dunkin Doughnuts coffee on the track-it ran mostlyonto the floor but some went right into the slot. It swelled up,but after acoulpe days it had dried and I sanded it and painted the area with Kills primer. No more problem. I think the key is making sure you let it dry totally before you try any kind of fix. Good luck.
if you got a hunk of steel put in the oven for a few min you want it hot but not to hot were it smokes or sets on fire if your steel block is heavy enough just set it on the bad spot if not add wieght to the block, this will draw out the moister and help shrink but you will have to do some repair
I started to fix the water damage last night. I did the work at night because I didn't want to affect rush hour traffic, any one from Jersey will know what I mean . It really wasn't worth posting any pics the swelling went down quite a bit as it dried. Last night I pulled up some tape , sanded the areas down and repainted. I let it dry till tonight and retape.
Could be a bit of a bugger
Tell us about your track, a picture or two would help to understand the situation.
Basic repair would be cut the bridge where the splices could have back-up board under the track that the track surface was screwed down to. A thin blade saw would also be helpful so you don't have to fill so much,
