Good sealant, quick delivery

Bought the Gutter Sealant. Arrived fast, took about 4 days to get to Perth. Product worked well for my leaky gutters. Easy to apply. No issues with the order.

Easy DIY roof repair

I ordered the DIY Repair Kit for a small section of my shed roof. The website was clear, and ordering was straightforward. Delivery was quicker than expected, arriving in about five business days. Everything needed was in the kit, including instructions. The Waterproof Sealant applied smoothly, and I used the Geo-Textile Fabric for a tougher spot. So far, no leaks, and it seems to be holding up well after a few rain showers. I had a question about curing time, and customer support replied to my email within a day, which was helpful.

Fantastic RV Roof Sealant!

I used the RV Roof Sealant on my old caravan, and it's absolutely brilliant! Application was so simple, I did it myself. It really sealed up all those little cracks and now I don't have to worry about leaks when I'm on the road. The whole process, from browsing the site to receiving the package, was smooth. I'm definitely coming back for more products for my next project!

Fixed my pond leak

So, my garden pond was leaking, which was a real pain. Decided to try Liquid Rubber's Pond Liner. Found it online, pretty easy to navigate the site. Placed the order, and it got to my place in regional NSW in about a week. Application was a bit messy, but not too hard. Now the pond is holding water perfectly. Happy with how it turned out, saved me from having to get a whole new liner.

Anyone tried returning an unopened bucket of sealant? Was it a pain or pretty straightforward?

N Nina M. 1 month ago

I returned some brushes that I didn't end up needing last month, and it was easy enough. As long as it's unopened, you should be fine.

N Nick Kaur 1 month ago

Yeah, returns were easy, did it last month. Just make sure you still have your receipt/order number.

Hey, wondering if anyone knows how long shipping usually takes for a roof sealant kit? I'm in Perth and need it kinda soon for a project.

S Shane Z. 4 weeks ago

Mine took like 5 business days to get to regional QLD, so Perth might be similar, maybe a bit longer.

M Mia K. 3 weeks ago

Yeah, I think their standard shipping is generally 3-7 business days for most of Australia. Perth is a fair way from the east coast so maybe bank on the longer end of that.

thinking about getting the pond liner stuff, is it safe for fish? don't want to poison my koi.

D Daisy 1 month ago

They have a specific product for potable water tanks, so I'd imagine the pond liner would be fine for fish, but maybe double-check the product page to be safe. It's usually listed if it's aquatic safe.

F Faith S. 1 month ago

I've used their tank liner for a water feature with plants and it's been all good. If it's safe for drinking water it's probably fine for fish, but always best to check product specs for specific animal safety.

Can you use one of those 10% off sign-up codes AND get the free shipping if your order is over $100? Or is it one discount per order?

W Wendy Ito 1 month ago

Nah, I tried that once, coupon codes usually can't be stacked. Free shipping should still apply though.

P Priya Foster 1 month ago

The codes usually just apply to full-priced stuff too, and you can only use one at checkout.

Are they doing any good sales around EOFY usually? Need to grab a bunch of stuff for a big roof job.

C Carly Q. 4 weeks ago

Yeah, EOFY is usually one of their bigger sale periods. Definitely worth waiting a bit if you can.

M Mark Nguyen 3 weeks ago

Black Friday and Boxing Day are also good for sales, but EOFY usually has decent discounts too. Keep an eye out for 15-20% off.

How does this stuff compare to like, Dulux or Gripset Betta? Is it actually better or just another option?

G Greg N. 1 month ago

I found Liquid Rubber DIY much easier to apply than some of the Gripset stuff I've used before. Less fuss, honestly.

W Wendy P. 1 month ago

It's a different beast, really. More eco-friendly than some of the traditional bitumen products. Depends what you're sealing and if you want a more DIY-friendly option.

Are these products actually made in Australia or just distributed here?

E Emma G. 1 month ago

Pretty sure they're an Aussie manufacturer, that's what their website implies anyway.

G Greg 1 month ago

Yeah, pretty sure it's Australian made. They push that fact quite a bit on their site.
