\"caulking<\/a><\/p>\n

We don’t think to look, but sealants (caulking) do expire so check the date before you buy.\u00a0 Most companies will put an expiry date on the sealant itself.\u00a0 When buying a loaf of bread or eggs, usually you can push the date a little if need be, but I don’t advise that with sealants or construction adhesives, especially with silicone.\u00a0 Old silicone has the tendency of not curing properly.\u00a0 What happens is after you apply the silicone, it is still “wet” and never cures.\u00a0 Save yourself some trouble and dispose of old sealants. Usually the sealants are good for about 12 months or so. \u00a0 Some other less expensive sealants like acrylic (alex plus is a good example) have a similar shelf life, however from my experience, you can push it a little longer if you expect little movement in your application as the acrylic tends to set (dry out) rather than stay wet as with silicone.<\/p>\n
