A fast History of Caulking and it is Ways to use Home Repairs
When caulking first came out, it would fill small cracks with very little problems, of flaking or checking in the future, but as people began to feel larger cracks, the caulking itself would begin to crack and outside of the edges from the areas that they were suppose to bond to.
Then they came out with silicone caulking, however, you couldn't paint it. There were plenty of contractors who use silicone caulking, since it promised not to separate or crack. This solves one problem but created another. When the painter was finished painting, there were little cracks or checks within the paint that was within the caulking.
Don't disappear yet, they came out with paintable silicone caulking. Now everyone was happy, believe that silicone was hard to neat and use and of course it's environmentally insensitive. Silicone was very successful, but was still being just a little pricey, when compared to regular caulking that was sold in those days.
In the building industry, one thing that sticks out a lot more than others is an, if a method is too expensive, it will not be used that usually.
Then comes the miraculous 15 year caulking, only to be outdone through the Twenty-five year caulking, and then the ultimate 35 year caulking. What's the difference between these? I couldn't really tell you what the difference is, however i can tell you this. Caulking was designed to fill small gap's, usually just one quarter inch and that's when it works the best.
Any gaps that are bigger than that, at less than a half inch wide, should use a polyethylene-based caulking. If you are planning to fill a gap that's bigger than one half inch wide, you should use a filler piece after which caulk between the filler piece and also the edges from the crack or gap.
As always, read the instructions around the caulking to ensure that you may use it on the products you will be repairing or filling. Using the right home repair product to fill the right hole, will prevent you against repairing the same spot later on or at least the near future.
