You probably have a few questions, so we’ve prepared the answers!
WHAT IS BOSTIK 3070?
It’s liquid cork – a flexible compound for filling expansion joints and gaps, mainly around floors, walls, and ceilings. It’s perfect for places where traditional cork sheets just won’t work – here, you can easily fill any gaps without a problem.
WHAT IS THE CORK BOSTIK GUN USED FOR?
It’s a manual gun for applying Bostik 3070 liquid cork, making it easy and precise to apply cork – even in those hard-to-reach areas. It’s ideal for a range of jobs, from small repairs to large installations. You can use it on floors, walls, and ceilings.
HOW TO USE THE LIQUID CORK APPLICATOR GUN?
- First, cut off the tip of the Bostik packaging, then place it into the gun and secure the plunger.
- Cut the tip of the gun nozzle – just enough to allow the cork to flow out in a thin stream.
- Before you start applying, protect the areas around the gaps with foil.
- Now you’re ready – squeeze the handle and cork will start to flow.
- Once you’ve filled the gaps, remove any excess material with a spatula or a silicone smoother.
IS THE BOSTIK GUN EASY TO CLEAN?
Yes, simply wipe the nozzle and cartridge with a damp cloth.
WHAT IS THE LIQUID CORK APPLICATOR GUN MADE OF?
It’s made of high-quality steel and aluminium.
You want to apply natural cork yourself, but have no experience and don’t know where to start? With the Bostik 3070 gun, you’ll manage just fine – even if it’s your first time holding anything like this.

#1 COMFORT AND EASE OF USE
You don’t need to be a DIY expert to apply cork properly. The gun is lightweight, so you’re not battling with heavy equipment while working. This is especially important if you need to apply Bostik overhead or in an awkward position. After just a few minutes, heavy tools can really take their toll – but you won’t feel that here.
Everything is intuitive and straightforward – insert the cartridge, cut the nozzle, and you’re ready to go. A perfect solution if you want to apply liquid cork yourself without the stress.
#2 FOR HARD-TO-REACH AREAS
There’s always a tricky spot to deal with during any renovation. Around doors, pipes, gaps under window sills – all those places can be seriously frustrating. Especially when you’re trying to apply the compound neatly, but your tool won’t let you get into the right position. That’s exactly when the gun makes life easier.
With liquid cork and the gun, you can finally use cork in places you wouldn’t even have considered before. Behind pipes, in corners, in narrow gaps – usually, we give up because it’s just too difficult to reach. Now you don’t have to – you can get it done properly, everywhere.
#3 CLEAN APPLICATION
There’s nothing worse than the mess left behind after a renovation. Stains, streaks, splashes – and a long clean-up afterwards. The cork gun has a major advantage: you work cleanly and precisely, without splattering or making a mess everywhere. The gun also features anti-drip protection, so nothing leaks out.
The liquid cork goes exactly where it should – not on the floor, your hands, or the wall next to it. The whole process takes less time too, as you’re not constantly stopping to wipe things down, clean your hands, or fix mistakes.
