What it's used for

  • Lining internal stud partition walls in new builds and refurbishments
  • Fixing to ceiling joists as a base for skim plaster or textured coatings
  • Dot and dab application direct to masonry walls as a dry lining solution
  • Infill panels within metal frame systems in commercial fit-out work

Fitting and handling

Store boards flat and off the ground in a dry, ventilated space before installation, keeping them away from damp conditions which can cause the core to soften. Fix to timber studs or metal framing at no more than 600mm centres using appropriate drywall screws, or use a suitable bonding compound for dot and dab to masonry. Once fixed, fill screw heads and joints with jointing compound before applying a skim coat or finish of your choice.

FAQ

What is the difference between square edge and tapered edge plasterboard?

Square edge board has flat, unrecessed edges on all four sides and is designed for use where the full surface will receive a skim coat of finish plaster. Tapered edge board has recessed long edges so that jointing tape and compound can be feathered flush for a seamless, paint-ready surface without full skimming.

Can 12.5mm plasterboard be used on ceilings?

Yes. 12.5mm is a standard thickness for ceilings where joist centres are at 400mm or 600mm. For spans beyond 600mm or where additional acoustic or fire performance is needed, a thicker board or a specialist product should be specified instead.

How do I cut plasterboard cleanly on site?

Score firmly through the paper face with a sharp knife and straightedge, then snap the board away from you over the scored line. Run the knife along the back paper to separate the cut. A plasterboard saw can be used for internal cuts and cut-outs around sockets or switches.

Worked well near the equator
Style: SPF 50
I bought this product because I was going to be in the field for a month, outside, every day, all day, in Tanzania at high altitude. A severe sunburn would be hard to treat in the remote area we were in, but also I am very careful about protecting my skin from aging. I had to have mineral based sunscreen because as a whitewater kayaker I know it’s the only truly water resistant kind and it was going to be sweaty. And since I knew I was going to be putting it on every day, and we didn’t have running water in the field (bucket showers only) I didn’t want it to feel gross. (I really wanted to try the spray but I didn’t want to put anything pressurized in my luggage.) And I had already discovered the Coola face sunscreen (30spf version) which had impressed me with how silky smooth and not greasy it is. Now this IS greasier because it is a higher SPF. BUT I think this product is as good as you’re going to get with the protection you’re getting. Like I said, I’m a white water tiger, so I have used a LOT of mineral sunscreens. This was hands down the most comfortable one I’ve used. And it was effective. I didn’t burn once—only time I did burn was when I forgot to put it on one day toward the end of the trip, when we were out for just a couple hours—and I got the first 2nd degree burn I’ve ever had in my life. That was what this stuff had protected me from, all day every day, the entire trip. I did tan a little but I think that was mostly from the few times I was not covered during short bouts or it was cloudy. For my face I used the Coola 50spf face product.

Love this stuff!
Style: SPF 50
I use this every day and I love how it is frangrance free and creamy. I have a very fair complexion and I will say it leaves a slight white cast but it doesn’t bother me because it almost makes my fairness more creamy looking. My skin texture has improved since wearing it daily and no allergies from it. I highly recommend especially if you have fairer skin otherwise it may leave a cast .

Excellent mineral sunscreen with minimal white cast.
Style: SPF 50
This is one of the healthier sunscreens I’ve found so far. You’re not likely going to find a mineral sunscreen that doesn’t leave some white cast. However, this one rubs in pretty good with minimal cast. You can dab on and rub in fairly easily… as long as you don’t use too much the white cast should be minimal. I am not sure how well this would work on darker skin tones. My arms are a medium skin tone… my legs are more of a light-medium tone. I prefer mineral sunscreens, and this is the best one I found so far and compatible to Supergoop mineral play. If you liked that one, you would likely enjoy this Coola one too.

Would not recommend
Style: SPF 50
I literally never write reviews but felt compelled to write one for this sunscreen because I was very caught off guard by all the positive reviews. This sunscreen leaves the most insane white sheen that never soaks in and gets on EVERYTHING. I put this on and drove to the beach and had sunscreen on my car seat, the steering wheel, the center console, the door, EVERYWHERE! It took forever to clean up and was such a hassle and that was after having let the sunscreen soak into my skin for an hour. Also the sunscreen is really thick and difficult to spread and makes you look ghostly white. Plus, the sunscreen has a really odd odor that reminded me of play dough? That might not be a negative thing for everyone but I found it unpleasant. There are definitely better mineral sunscreens out there. For the price I expected a much better product.

Sticky and white
Style: SPF 50
The sunscreen has a very sticky and thick texture. It will keep you from getting sunburnt, but it will also leave you with a white color.
