a few days ago it was raining and I discovered water dripping from the vents in the kitchen and bath. I took it to my local trailer/rv repair place and paid to have the roof calking all replaced. (I have had work done there a couple times before with good results.) I checked the job when I got home and the calking was semi cured. (I have used similar calking before where it takes many days if not weeks to cure completely to a hard state.) They did the work the day before yesterday and it rained last night and this morning (very light intermittent showers). The invoice specifies Silkaflex - but not which type. The rain doesn't seem to be affecting it. But I noticed that it looks like they didn't even clean the roof before applying the calking and it looks like they applied it right over the old calking. Does this sound right to you guys?

Sikaflex is preferred on several websites for caulking, (Some prefer Dicor) but removing the old caulking and cleaning the area is also recommended. Maybe you should have done it yourself! :)

thanks for the reply EMD. I used to do that stuff myself but I currently have health probs that prevent me. Don't know if it matters but the old caulking was in decent overall shape - never leaked before. The guy said it was just getting to the point of needing fixing. Guess I need to talk to him about it. They are the only repair place around so I hope I don't loose confidence in them.

I ordered caulking on line and spoke to a real person. They had every caulking available. My original choce was Sikaflex. They had it but recommended Dicor. They said it takes Sikaflex a long time to cure and it picks up dust and dirt during that time and dries softer. Also that Sikaflex drying slows with some cleaning chemicals and that is why they also sell special cleaning solution. They did say it was also a very good product but I would happier with Dicor. I bought Dicor self leveling and some eterna bond tape. Did the job myself. Cleaned with mineral spirits first.You can download Sikaflex specs. I did before I bought the Dicor.

IF YOU CAN SHOW THEY DID NOT REMOVE THE OLD STUFF? i,D BE ON THEM IN A HEART BEAT, NO REASON FOR BAD WORK. go gettem.

Recaulking over older caulking is not an issue in and of itself.IF old caulking was in decent shape----not crumbling, flaking off, become chalky...then new over old is OK
