I buy this regularly and prefer the smaller tube. I goes off rather quickly after opening but this screw tip tube does prolong the life a little. Great being able to get both black and white at BCF

Is very strong and waterproof when applied carefully.Is the best thing also for fixing athletic shoes!

Have used it on several boats, from installing gunwale rubber to sealing bolt holes through the transom and a seal on through hull fittings. Good product. Never had any colour change issues. Sika have all the details on their website. Would be nice if bunnings stocked the large tube as well as the small.

Easy to use and great for outside car seals. I used it for a new clearance light seal.
I purchased this product after a recommendation from a Bunnings member. It was used to seal a patch into the bottom of a Pot so that it could be used as a water feature.The Sealant does the job, but do your homework on the Sika website first to get the best info re preparation and use.
Easy to work with but don't make the mistake of cutting the hole in applicator too small or tube will burst. Sticks like to a blanket, worth picking up a small bottle of meths to get the stuff off your hands and don't over estimate your ability
This is a terrible product. The colour is white when applied but once it dries it turns YELLOW! if you are applying anywhere visible keep this in mind, it made me waste loads of time and money re-buying and re-doing work.
Used to seal around an aircon, works okay.Would have preferred the 310 tube rather than buying multiple 150mlShame about the website and help in-store - both useless!The packaging did not explain "Method of Application" or "Surface preparation".Bunnings website did not provide a link and no pamphlets in-store and retail staff were of no help.
A handy adhesive for many specialised applications. Really important to follow the instructions regarding preparation and application. Works well in the appropriate situation...
I brought it a couple of weeks ago to fix and seal my washing machine drum but let me down didn’t work so brought standard sikaflex works well
