FAQ
Frequently asked questions
Q: What is the difference between Ultra Clear, Ultraclear and Fulaseal 701 Flexible Ultra Clear?
A: There is no difference - it is the same fabulous product.
Q: What surfaces can I seal with Ultraclear?
A: Lots of people use it to seal gaps and cracks in their homes as outlined in videos under the “How to” tab. Ultraclear can also be used to seal polycarbonate roofing. Due to its water resistance it can be used to seal gaps and cracks in bathrooms and kitchens. It can also be used with fibreglass, glass, metal, plasterboard, concrete, cement sheet, ceramic tiles, brick and timber. It can be used with plastics, but test it first!
Q: Do I need to buy a caulking gun?
A: Yes you do. There are lots of choices for caulking guns at your local hardware store. Make sure to invest in a caulking gun that withdraws the plunger when you let go of the trigger. Some cheaper guns maintain pressure on the tube when you let go of the trigger causing the Ultraclear to continue to spill out of the gun. We do have professional caulking guns for rent in Melbourne .. Learn More.
Q: I've never tried caulking gaps myself yet. Do you provide guides on how to go about this?
A: We do have how to Videos to ensure you get a great finish. Just go to the How To tab, and you should see all the instructional videos you'll need for a successful DIY caulking job. And remember, Ultraclear cleans up in water, so if you do make a mess, it is easy to wipe it off (before it dries) and try again.
Q: How do I make a neat finish?
A: Within a few minutes of application, finish the surface with silicone spreaders, wet spatula or other smooth implement. In some cases, such as with air vents, we find that a damp finger gives a good finish but be sure to wear a disposable glove.
Q: Does it shrink once it is installed?
A: Yes, It can shrink a bit if it has been applied in a thick manner. Just let it dry completely and reapply a thin layer over the top of the existing sealant.
Q: Is this difficult to clean up like silicone?
A: No. One of the reasons we love Ultraclear is that it is a water-based sealant so it's very easily cleaned with water. Just wet a piece of cloth with water, and wipe off the excess sealant from the surface. Whilst it is easy to do, it is important that this is done BEFORE the sealant dries. Once Ultraclear dries it is much harder to remove.
Q: What if I applied Ultraclear without first cleaning the area of application?
A: You will be sealing the dust and other foreign particles in too. Cleaning the area to be sealed FIRST is a critical step to ensure maximum adhesion. Ultraclear dries to a transparent finish. It will lose that transparency if you can see dust and grime sealed in with it and it will have a yellow hue.
If you missed cleaning the surface first before application, and the sealant is not yet cured, you can use a damp cloth to remove it. Once the sealant is cured, you will have to use a knife, scraper, or other mechanical means to remove it.
Q: Can I use this on a metal surface?
A: Yes. Although adhesion to metal is a bit different when compared to timber or cement. This can be improved by light sanding prior to sealant application.
Q: How long will it take for the sealant to cure?
A: Full cure is normally achieved in 5-7 days depending on bead size, weather conditions and substrates. Larger sections of sealant will take longer to cure. Fulaseal 701 Flexible Ultra Clear sealant relies on evaporation to cure; therefore applying sealant on non porous substrates will extend curing time. During warmer weather, the sealant will cure much faster. During winter, you may need to heat the area to ensure that Ultraclear cures.
Q: Can I paint over the sealant?
A: Yes, it can be painted with water based paints once tack free (approximately 30 minutes). If you will be using oil based paint, though, please allow 5-7 curing days before painting.
Q: How flexible is it?
A: Offers permanent flexibility with up to 25% joint movement capability.
Q: Will it go mouldy?
A: It is mould resistant, so great for use in bathrooms and kitchens.

What is draught proofing, and why is it important?
Draught proofing means sealing up all the gaps (big and small) where air sneaks in or out of your home—around windows, doors, vents, chimneys, and even curtains. It’s one of the easiest and most effective ways to improve comfort, reduce energy waste, and lower your heating and cooling bills. Generally draught proofing is the first step in you making your home energy efficiency. The major component of a home’s energy costs is used on heating and cooling. Your home can’t be effectively heated or cooled if you can drive a “mac truck” under your front door.
Will this really make a difference to my energy bills?
Yes! Draught proofing reduces how often your heater or air con needs to run. Less hot air escaping in winter, less heat sneaking in during summer = lower energy use, more comfort, and more savings. In the ecoMaster test house, which was draught proofed more than 20+ years ago, we saved 50% of our $2,500 heating bill in the first year after completing it. And of course, we have continued to save that amount every year.
How do I know where the draughts are coming from?
A walk-through your home on a windy day can help you feel where air is leaking in (like under doors or around windows, chimneys and exhaust fans). You can also check unused heating vents, behind curtains, skirting boards, cornices and picture rails —these are often the hidden culprits.
If you’re not sure where to start, you’ve got three great options:
You can try to track down the draughts yourself, or get a little help with our Find and Fix My Draughts program—designed to guide DIYers in spotting every sneaky gap in their home. Prefer to leave it to the pros? We can connect you with a trusted draught proofing technician in your area for a full in-home assessment. Just get in touch and we’ll point you in the right direction.
What products do I actually need?
That depends on where the leaks are!
- Draught Dodgers for effectively sealing doors and windows.
- Chimney Draught Stoppers block open fireplaces.
- Goodbye Heating Vents seal off unused ducted heating.
- DraftStoppas stop airflow through ceiling exhaust fans.
- Invisible Pelmets help block airflow and heat loss behind curtains.
- UltraClear seals gaps and cracks where one surface meets another.
If you’re not sure, start with either work with the online program Find and Fix My Draughts, follow the Draught Proofing Information Hub one room or hire a draught proofing technician. Or contact us for a referral to a trusted draught proofing technician in your area.
Can I install draught proofing myself, or do I need a tradie?
Most draught proofing products are totally DIY-friendly—especially with the help of our video guides. They’re designed for everyday Aussies, not just seasoned professionals (althought they also buy ecoMaster products). If you’re comfortable using basic tools, you can do this. We indicate where any particular product requires an experienced hand.
