I have tried other brands of polyurethane sealants and always regretted not having spent an extra dollar or two on Sikaflex. I have never seen a failure of this sealant, even if applied outdoors, exposed to the elements for many years. It&#8217;s adhesive properties are amazing. If you put something together with this, it isn&#8217;t coming apart. This is truly a lifetime caulking. Not like that water based modified silicone whatever junk. <\/p>\n<p>It isn&#8217;t the easiest thing to apply, it tends to string out at the end of the bead &#8211; my friend in the industry calls that &#8220;having legs.&#8221; It can be smoothed out considerably, the best I&#8217;ve found for that purpose is WD-40. Wet a finger with WD and it works like a charm. WD also works great for cleanup of this material from hands, caulking gun, whatever. <\/p>\n<p>It comes in a wide variety of colors, Home Depot carries a limited assortment of colors, but the masonry supply place I do business with has them all &#8211; at a higher price. This is a moisture curing material. It does have a shelf life if unopened. Seems like a year, maybe two. The biggest downside to it is once the tube is opened, it needs to be used soon. I&#8217;ve tried a variety of caulking gun &#8220;plugs&#8221; and caps and none worked any better than a pencil stuck in the end. And at that you may get it to last a week in cool weather. A similar material is the <a href=\"http:\/\/amzn.to\/2nc1UiO\">Sikaflex Self-Leveling sealant<\/a>. I purchased this by mistake, and it is self leveling. No amount of effort on my part could get it not to flow to level. In the right place that is a good thing. In the wrong place a disaster. <\/p>\n<p>This is an ideal material for using with a <a href=\"http:\/\/kk.org\/cooltools\/pneumatic-caulking-gun\/\">pneumatic caulking gun<\/a>.<\/p>\n<div class='ctx-module-container ctx_default_placement ctx-clearfix'><\/div><span class=\"ctx-article-root\"><!-- --><\/span>","protected":false},"excerpt":{"rendered":"<p>Best construction sealant<\/p>\n","protected":false},"author":76,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_mi_skip_tracking":false},"categories":[53],"tags":[],"acf":[],"_links":{"self":[{"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/posts\/30633"}],"collection":[{"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/users\/76"}],"replies":[{"embeddable":true,"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/comments?post=30633"}],"version-history":[{"count":1,"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/posts\/30633\/revisions"}],"predecessor-version":[{"id":30635,"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/posts\/30633\/revisions\/30635"}],"wp:attachment":[{"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/media?parent=30633"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/categories?post=30633"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tkdev.kk.org\/cooltools\/wp-json\/wp\/v2\/tags?post=30633"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
