@PC Yes I still use it on occasion, it's okay but some of the other foam backerboards are more rigid and have a better texture for holding tile oh, so I'm not married to go board but it still does the job

Are you going to do your own water test on this product set up the way you installed it red guarding seams only? Great vids

[@StarrTile]

I don't feel it's necessary because the goboard is a foam product which will not leak, and the caulking will not leak so it would serve no purpose

[@capt2278]

@@StarrTile hmmm.. just because it says waterproof, would still love to see you test it. And I have seen closed cell foam gain mold. But, I love the idea of finally getting a waterproof board in to the bathroom like we've seen ZIP boards for the outsides of houses now. Bout time.

[@tyedazole1690]

I installed GoBoard in a shower. Great, great stuff. I built a box out of it and filled it with water. I used Kerdifix to caulk the seams. No leaks for 2 weeks. I then put it outside in zero degree weather froze it for several days. After it thawed, it stayed watertight. I have a square of GoBoard that I put over a drywell as a cover secured with a brick. It remained impervious to water and while it discolored due to the environment, it didn't grow any mold. This stuff literally could be submerged for decades and not be affected.

[@warrencogburn2198]

I have used quite a few foam boards over the years. The flex is not a problem when using bigger tiles. I like go board ok and the price at Crossville is less that the rest. The biggest problems I’ve noticed are. Itchy that is because the stuff that is for bonding is falling off. Also I’ve noticed red guard peeling off some which seems to be remedied by damp wiping. I think cement board with waterproofing is best but waterproofing cost to much in time and at 60 those boards are getting heavy lol

[@jayviz]

A truly excellent video! I am building an outdoor cabinet which I want to keep lightweight and I am going to face it with faux stone tile. Do you see any downside to using goboard in an exterior application like that?

Only movement, as with any tiled application expansion and contraction probably more outside.

Very timely video. I just used this product for the first time also. I love how light it is and how easy it is to cut. I have to order it from Lowes as they do not stock in store. The manufacturer recommends using a polyurethane sealant for the joints not silicone and unfortunately it takes 7 days to cure. Other than that I love love love this product and will continue to use. Keep up the great work.

You mean can be painted in 1hr fully cured in 24hrs. ... That is the OSI Quad Max. Goboard has other recommended sealants as well.

[@blipco5]

Per Johns Manville, you are to caulk the edge before installing go board then let it squeeze out as you install it. Not caulk after.

@@nathan187dogg I’m just finishing my bathroom. I spaced the boards 1/8 inch with nails because I didn’t want to deal with the sealant at the same time as hanging the boards. Afterwards I squeezed in the polyurethane sealant into the gaps. The sealant firms up the boards between studs also. And I also used the proper GoBoard screws, they are far superior to everything else.

[@davo912]

WRONG...the preferred method is installing with an 1/8 inch gap around all edges and applying the sealant to the gap after the install .and 1 inch on the sides of the gap.. Go look at their instructions. PLUS they do not recommend the use of silicone sealants..

You do great work love your videos keep cracking down on some of these contractors, I'm also an installer and watch your videos its nice to see someone who actually does thing right. But if you end up using Goboard more often I would recommend using the washers just because of all that weight of the thinset and tile on the walls. I used Goboard on all my shower and I'm just not comfortable with just the screws because it's foam. Or worst case just put and liquid nails on the studs and then put the Goboard on. It's just something I had an issue with on one project. But man you do great work. Oh and check out the Hydroblock system I started using it and I love it, let me know what you think about it.

Yes...any wallboard can be wet shimmed, though you'd probably need to do it the entire length of the stud since it's a bit flimsy

[@holdernewtshesrearin5471]

I like the Goboard as well. I dont get the use of silicone though. If you plan to use Redgard over the Goboard why not simply fill the seams and screw holes with it? Thats all i do. I fill any deep gaps, seams and screw holes with Redgard. Its usually sufficient just to apply it with paint brush but if any gaps are larger than 1/8" ill use a putty knife. Once dry i apply a second medium heavy coat and embed 3" to 6" fiberglass mesh cloth or tape on all seams, corners and around the drain all the way to the edge of the drain opening. Redgard fills 1/8" seams, gaps and 3/8" screw holes/divots just fine and is the recommended process as per Redgard instructions. Its only when someone tries to fill too large a gap or hole that it will crack. If ever filling any gap larger than 3/16" or so i do it in atleast 2 or 3 coats, never applying it more than about 1/8" thickness, preferably less. Along with the fiberglass cloth/tape it has never failed me. Im not questioning your methods, what works for you works for me. Im just curious as to why you would introduce another material and step/process rather than simply continuing with the material and process already in use. Btw im experimenting with a new process to deal with water intrusion at the curb. I have a demo built and currently in testing, going on 2 yrs now. Ill let you know if succesful and show you how to do it. Its a way to eliminate or atleast mitigate any water intrusion from the tile and grout as well as any penetrations such as for shower glass door/surround mounting/pivots etc and can be used on the curb, benches and knee walls. In fact, i might want to get your opinion and input on it. It could be a new system in the works. Stand by!

I wouldn't use silicone only because nothing really bonds to it. If you're going to use redgard anyway, I would have just used that at all the seems and especially the screws. Do they recommend a certain type of mortar be used for setting tile? Just curious, because that would probably add to the overall cost as well. I'm a permabase guy myself. $10.00 a sheet. Install that and 2 coats of redgard with fabric at all seems. To each his own though.

Being foam it must have an R- Factor of sorts? Certainly better the concrete board.

[@GilBatesLovesyou]

Can you "wet shim" with Goboard? I dunno if you've watched Sal's channel and him doing that with Kerdi foam board, but that seems like the biggest advantage of foam boards, not that they're waterproof. What you do is blob thinset on to your studs, position the board however, then screw it in until you hit straight on the level. Kerdi 100% endorses it, I'm skeptical of how well it works, but man that seems like a huge timesaver.

[@andrew12361]

I think this is a year later but the GoBoard installation guide says as "an alternative to furring strips, GoBoard can be wet-shimmed by applying thin set mortar directly to studs." So, I guess you can 👍

Go board is made of polyisocyanurate. Which is exactly what insulation sheets are. Their website says that in the very first sentence.

I was under the impression that quickset would not stick very nicely to silicone... anyone actually tests this idea.... silicone tends to be pretty resistant to adhesives and if there is any water or humidity, over the years silicone tends to mold and shrinks.... I would rather put redgard over the silicone to prevent those cracks that silicone will likely to form over the years.

That's why you must vacuum out the mortar surface very well to get up all the dust before you put the silicone down, and then you push it in and smooth it out, works for me every time, but you are right I waterproof over it anyway

Surprised you used silicone for the sealant as the manufacturer recommends a polyurethane sealant to be used. They sell their brand of polyurethane sealant but it is not available in my area so I use another brand that they have on their list of other approved sealants to be used with their boards. I too put red guard or a liquid membrane on anyplace I used the sealant for an extra safe guard and add an embedded tape with two coats of red guard at the base of the walls/shower pan.

You gotta admit, Isaac with the floats is at the top of the KZbin tile game (among English speakers anyway.) Floats like that are how they do it in Asia and I'm assuming Jamaica, just without lath and straight to concrete or bricks. I wish I floated my walls instead of using Wonderboard, because as you said, Wonderboard/Durock bends too much with your studs, and sheetrock does hang flatter for sure, and in every country but litigation happy USA the liquids like Aquadefense are spec'd for sheetrock. I will say though, you are wrong on the wallboard. Our oldest mastic and subway tiles straight to I'm assuming normal sheetrock job did have some loose tiles at actually about shoulder height where water would hit most, and the sheetrock section near the edge of the tub with tiles on it did disintegrate into nothing, and that was just a normal tub surround, not an embedded shower pan. Mind you the job was probably done in the 70s and lasted into the 2000s, but still.

[@StarrTile]

Actually Issac shows himself screwing up jobs a lot, so I'd never hire him despite his floating walls...which most tilers CAN do but don't because it's time consuming, labor intensive, messy, and antiquated given newer methods. And although floating is common in Jamaica, buildings are block and concrete too. The 40 year old sheetrock/tiled garbage is not what we do anymore, 4x4 ceramics aren't used in showers, we're waterproofing, using better grouts, sealing, better & larger tiles insure our work far outlasts the 40 year garbage despite what backer is used.

The goboard is attached to studs right? Studs, especially on an outside wall, will expand and contract with temp swings and house settling. As long as the caulking is very elastomeric and not sensitive to temp swings, then a crack shouldn’t develop at the joints. You did right by leaving an 1/8” gap at the seams.

You like hardi backer

[@StarrTile]

The only time that I like hardibacker is for a steam shower

[@vincentlenci]

I got go board yesterday from my tile suppier. in northern NJ...im a beginner single handed doing my own and had a2 major strokeshad I known earlier. such a breeze but is itchy! Hardee on the ceiling!!!I will not go thru that again!!

[@loug1612]

you like it because age it’s catching up with you.😂

[@ackackdac]

Your supposed to put the sealant on the edges where goboard meets another sheet!!

[@StarrTile]

Yup... and putting it on the outside also make much better seal 💪

[@unapologetic7900]

Wow, this stuff is really expensive, it's like twice the price of Durock!

[@RealGame101]

Yeah saw some today and was like what the hell

[@wef0711]

It is, but it is about 6 lbs vs 39lbs for a sheet of durock. Worth it for $100 if you're hanging 5 sheets. When compared to Kerdi, its super cheap, lol.

[@ThorD4602]

Yes, but durock is heavy, has annoying mesh in it, not easy to cut and isn't waterproof. So goboard is actually cheaper than durock in all meaningful ways. Try it.

[@stevenperry4941]

I will never use cement board or any other backer board other than the GoBoard!

[@donkeydump63]

I just purchased materials for a bath I'm tiling. My plan was to use go board for the tub surround and shower enclosure and HardieBacker on the rest of the walls thinking it would be cheaper. Little did I know the latter cost $7 more per sheet. That not only makes GoBoard the cheapest backer board but also one of the easiest to install. This one's a no brainer

[@rickhoupt6933]

You lost me when you busted out the garage “Dap” caulk. If you want it to stick and last. Urethane. Why spend extra on the board only to use inferior caulk.

[@StarrTile]

First of all polyurethane is chemically toxic and that alone would stop me from using it, I get enough silicas into my lungs with all my mortar material, secondly and more important it is a sucky product to use around water. I use what I feel is appropriate and that's my choice and it is my warranty

[@rickhoupt6933]

I apologize it’s not Urethane. It’s silyl-modified polyether. Which is JM’s GoBoard pro sealant. I am just not a fan of anything Dap makes. You warranty your work with it so if you stand by it that’s all that matters.

[@MrFuckface2013]

@rick 100% my thoughts too.

[@dr66ss396]

grout is porous, green board is absorbent. If is not waterproofed, it will be wet. I've done several over the years that were saturated (lower foot) when Redgard is not used. A lot of lazy tile guys out there

[@leaguefixesyourmatches8259]

Still using Goboard in 2023?

[@StarrTile]

If I have a need for it.. it has its use and purpose but I don't use it by default

[@jameslewis6567]

great to see your converting to foam, at least partially, with these boards you can use thinset adhesive over the studs before you fit the boards if the studs are out of plumb or not straight, I also worry about the deflection if these boards are subject to impact compared to plasterboard a perfect install but if you do need to use a proper sealant polyurethane or ms hybrid type sealant applied to the board edges as they are fitted and push boards together, silicone or painters caulk isn't really suitable. i wouldn't recommend using a a tube of sealant at all, to much messing around and looks a mess, the proper ms sealant sticks like shit to everything and makes a mess, its also expensive and not a true waterproofing system you could guarantee, its quicker and far better to use a jointing tape with two part cement/acrylate ardex/wedi/schluter etc, job done

[@StarrTile]

I'm only slightly concerned with the deflection in the boards, and you can't really wet shim a board like that and still attached it to the studs because that by itself will cause some type of pushing in, it's almost like if you wet shim you have to wait till the next day... I suppose putting a straight edge on the studs will determine whether I use a stiff wall board or this stuff. To your point about 101 percent waterproofing on a wall, as I mentioned in a video I just don't run into issues when there isn't waterproofing it on them at all so anything we do better will just be insurance, nothing more.

[@jameslewis6567]

@@StarrTile for sure if you wet shim you have to wait for the next day to screw your fixings home. and your defiantly right about the wall getting wet, (excluding some showers I've seen myself that have zero ventilation/shower enclosure goes to the ceiling, causing the shower to constantly be damp) the walls don't get damaged just the lower portion so i suppose the advantage of a board like this is water can not migrate up into the core of the board if it where to touch the shower floor. even if the board is set above the shower floor water can still migrate up the thinset adhesive and or tile and its not uncomment for the void created when the shower board does not come into contact with the pan to fill with water, there is less area for any water behind the tile to escape into the pan and an entire wall surface above where water can potently penetrate, especially where a shower door/profile gets wet and the profile fills with water

[@davemotti8070]

I like dense shield

[@davemotti8070]

Sadly it does get a bit itchy. It cuts easy no issues 15 years. So it works. Also I’m slow to try new products. Especially when liability falls on my head

[@nathanielobleanis7049]

Hey how r u. My name is Nate CEO of Bathroom Bling LLC I. NY and I love to use hydro band board by laticrete. Excellent product. Check it out. Down side only sold by distributors but in my area I have a bunch of them.

Read fair? You mean redgard.. You say something definitive without any proof or evidence to back it up. Put in the search box regard on cardboard, also redgard on sheetrock
