All surfaces must be clean, dry, and dust-free. Remove loose coatings, old sealant, and mastic before applying. Apply nozzle and cut cleanly at an angle of 45 degrees with an opening slightly larger than the gap to be sealed. Use a standard sealant gun. Apply with steady pressure and keep the gun at a constant angle for best results. Smooth down within 20 minutes of application using a wetted spatula, piece of wood or wetted gloved finger. WHERE TO USE IT? PERFECT FINISH WITH NO SANDING REQUIRED! Sika is your best ally! Review: Good quality caulk - I purchased this caulk for some general house hold cosmetic touch ups before decorating. The price at the time of purchase was very competitive for a known brand. No higher in price than a lower end quality caulk from national DIY/trade counters. It's a nice bright shade and very easily applied. The texture on application is faultless, very smooth and remains malleable for cosmetic touch ups for a fair while after application. That said the product is pretty much set within an hour so fast curing times on projects where time is important. For best application I would recommend cutting the nozzle at about a 45 degree angle and cut to a thickness consistent with the area of coverage. I dare say less is more as there can be a lot of wastage when smoothing. Once applied to your area, mix some water and washing up liquid in a spray bottle. Then spray the affected area and gently rub off the excess and smooth into the final position. The spray will stop the excess going all over the work surfaces. For best result I'd suggest a mastic forming tool but failing that a clean finger is fine. Having worked in the construction industry my working career, I'm pleasantly surprised with this and happy to recommend. Review: It's caulk and it works - This caulk is excellent, dries quickly and supplied at a good price. It does not match Dulux Super Brilliant White one coat wonder paint exactly, nothing's perfect - but if you want to have a laugh read some of the other one star reviews - my favourite is the bead of caulk that must have been put on without the applicator nozzle, a centimetre thick and someone wonders why it slumps and has not set three days later. And if you really want to "crack up" search for the one that is surprised that they can't actually fix a cracked sink with it. ## Features - Contains a mixture of 5-Chlor-2-methyl-2H-isothiazol-3-on und 2-Methyl-2H-isothiazol-3-on (3:1) (CIT/MIT).

I've tried cutting, piercing, everything... Can't get it open!!** A: People could be a little less patronising, some of us don't have an much knowledge of /have never before used hardware tools and products as others :) **Q: If need be, can it be sanded?** A: It doesn't really need to be sanded as it has quite a smooth finish. Just squeeze it into the gap and with a slightly damp fingertip, smooth it out. I always have a damp cloth to just wipe off any excess that goes somewhere I don't want so I don't run into the problem of needing to try and sand it. If you have gaps between the skirting board and wall (like some of mine have), it's great for filling these in, but I always make sure after I have run my finger over it to wipe off any excess that may go up the wall a bit so it doesn't leave any sort of ridge. As it has some flexibilty I find that if you try to sand it, it tends to ball up a bit. Hope this is of some help. Noelene **Q: Can i use it to fill in between liner paper as some of it has gaps in between liner paper.** A: Caulk can be used for all D.I.Y and decorating tasks, great stuff for filling all gaps,holes,cracks, can be painted over, no problem. Hope this helps **Q: what sealant gun's size should I buy for 330ml? 350ml?** A: 350mm ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality caulk *by J***Y on 18 April 2023* I purchased this caulk for some general house hold cosmetic touch ups before decorating.
