Cutting Cement Board

[ghislain6313]

askthebuilder guy, you rock man.

[kingcahoj]

AWWWHHH!!! THAT WAS EASY!

[gotquickness44]

Better off using HardieBacker.......you score it once and pull up. Done!

[MrSerpent89]

hello i have a custom made reptile cage and for lighting/heating i have a porcelain bulb holder, i have a 60 watt bulb for heat, and i noticed it gets my wood hot and im afraid eventually it might start a fire, this one guy said he put a cement board in between the porcelain bulb holder and the wood, he said it keeps the wood from getting to hot and he said the cement board is much more heat resistant than wood so i would not have to worry about causing a fire, is that true?

[tomasbobby]

You wil find h easiest way to cut cement board is with a cheap disposible hand saw

[AsktheBuilder]

@tomasbobby The folks who are conservationists aren't going to like this method. We already consume too many things each day, and now you want to throw away saw blades?

[msa1985]

@AsktheBuilder is that a rare tool? I've never seen it in home depot.

[AsktheBuilder]

@msa1985 It's not rare. Don't get me started on HD. They only stock a very TINY percentage of the products and tools that exist. Did you know that the footprint of the average HD store is SMALLER than the size of the average lumber company? That shows you how little lumber types and sizes they stock. Now extend that to every single category in a HD. Consumers like you are getting dumbed down by HD each and every day. It's very sad. You have no idea what you're missing.

Tim,

Thank you so much for the informative video! I'm wondering--is there a name for the carbide-tipped tool you used?

Thanks!

[AsktheBuilder]

@echtconservative Beats me. I bought it at a tile store well over 20 years ago.

[dudewashere100]

@AsktheBuilder @echtconservative

its called a Scoring Knife/Blade... you'll find plenty of examples if you google it.

[dudewashere100]

@echtconservative

[MitchellHurwitz]

@echtconservative It's a "Backerboard scoring knife"

[1fishdreamer]

I want to see you cut some round shapes. Thanks

[AsktheBuilder]

@1fishdreamer I want to see some other videos at your channel about what you know, not what you don't know. :->

[rharley5652]

Tim ,.

watching your videos,..I Felt That I was workin with a Journeyman through my whole bathroom remodel job !! I took your floor-tile , mortar & grout videos an applied them to my wall tiling and the job came out perfect ,.I used Hardie backerboard,.1/2 &1/4" ,.great stuff !

Again thanks for all your Videos !!

Keep up the good work !!

[AsktheBuilder]

@rharley5652 Hooray! You can help by spreading the word to all about the videos. I need people to watch them to fund the making of new ones. The same is true for my website. Traffic is what allows me to offer all of this for FREE. So publicize to every person, group, forum, etc. that these videos and my website are out there. Thanks in advance.

[rharley5652]

Thanks Tim,..

I did silicone those corners,. job came out great !!

thanks to your videos!!!!

[AsktheBuilder]

@rharley5652 You're most welcome. You can help by promoting them to all you know. I need traffic to the videos to be able to allocate resources to tape more of them.

[godofwar5234]

My family is in the tile bussiness, and I tip to all of you guys is that before you lay down the cement board, put some thin set down with a quarter notch trial BEFORE you lay down the cememnt board and take a nailgun or screwgun to it.

[HistoryProvesMeRight]

@godofwar5234 i use polyurethane, its holds better

[rharley5652]

hello Tim ,..when useing backer board in a bathroom tub an shower area ,.is it ok to use silicone sealant in the corners to seal the backer board ?

[AsktheBuilder]

@rharley5652 Yes it is.

[rharley5652]

@rharley5652 ,..

Tim this is not spam !!

[AsktheBuilder]

@rharley5652 I'll reply again: I feel it's perfectly fine to caulk the corners with silicone caulk before installing the tile. I've done it that way for years. I don't know who flagged your post as spam.

[madpaddy73]

how fire resistant is it??

could i use it to line the inside of a outdoor fireplace?

[monbagsik]

Mr tim, quick question what kind of tool to use to put hole for the water suppy and shower head?

[AsktheBuilder]

Crude method: Hammer and cold chisel

Fancy method: Diamond studded hole saw

[monbagsik]

i forgot what kind of screw you use to attach the cement board in the wall could you use a regular drywall screw?

thanks for the quick reply Mr. Tim, you are really doin a great job!

[adamalden]

OH GOSH!!! THIS SURE WAS A GREAT BIG HELP! Thanks! I would have never figured this out on my own!!!! Jolly Mr! U r smart!!!

[pachuco5]

Actually, i think i will try that just now.... I'm remodeling the bathroom and those backerboards are just asking for it.

[hurricaneheide]

Thanks Tim! Your videos are perfect for those of us who don't mind a little sweat equity in place of a $400 dollar blade and saw.

[AsktheBuilder]

You're welcome. That's the idea. Many homeowners just can't justify the cost of the expensive tools for the one or two times they might use them.

[cacaman01]

Alright, I'm gonna try it right now, but only because you said so.

[Iluvbadgers]

i dont get it. what will happen when you use a circular saw. i have one and is an abrasive or diamond blade better. please respond. thanks.

[AsktheBuilder]

Vast amounts of dust that contains silica. Google: silica dust health issues

[jocky102]

just wear a mask and your fine

[dalethomasdewitt]

If you really trust those masks for a good seal. The best bet is either hold your breath +and/or downwind or a scuba tank. Lungs are the most abuse organ in the body.

[Eco4life777]

what is the best, attach a backer board to subfloor or apply wood finish before tiling?

[AsktheBuilder]

If I understand your question, the Tile Council has approved both methods for years. Go to their website and see if they are promoting one over the other.

[soaringman]

Hey, thanks for this video. I am doing my shower so I googled how to cut cement board and this video came up. I was going to cut it that way but wanted to make sure

[AsktheBuilder]

You're most welcome!

[thecarpetking]

i cut outdoors with a circular saw, much faster, and cleaner cuts

[wan5446]

there are any suggestion how to render the floor cement..

? I always get trouble when to deal with it..please..

[AsktheBuilder]

If I understand your question, I believe I cover that in great detail at my website. Read all of my columns about shower-pan floors and Cement Board. You will discover them in the Ceramic Tile category.

[ActressAlyssa]

I'm tiling my bathroom floor do I have to use cement board on the floor before I tile or can I just tile right to the wood floor? Could you also give me a few tips for around the toilet? I'm afraid that the flooring is going to be higher than the floor drain. I sure do appriciate all your advice and tips. Thank you so much!

[AsktheBuilder]

I can't give much help it this tiny space. You need to go to my website and read all of my toilet and tile columns for your answers.

[seanseanseanseansean]

I'm not going to be like the others and bother you about masks. The pussies!!!

[fossilman2]

how about making a round hole for the tub hardware

[AsktheBuilder]

Use a cold chisel or a diamond hole saw

[fossilman2]

yeah, thanks that's what i was thinking too, I have a set of those el cheapo chisels will give it a go.

[Skunk980]

does the dust from cinder block and concrete contain silica. please respond. thanks. Alex

[AsktheBuilder]

Yes.

[xXsnitchyXx]

another top vid tim

very usefull for the handyman

when we run your method on site i tend to leave the line maker there that ways i can run the knife fast to start the line and then remove the pice of timber to allow you to apply more pressure

tho on site we use electric shears to cut this board ,hence no dust and no noise ,tho we are prof so we have expencive tools to make our job easy

but tim im always impressed with your vids

[AsktheBuilder]

Thanks! Yep, shears are the way to go but as you know, homeowners can't justify the cost.

[xXsnitchyXx]

yes ofcourse tim ,think my last pair cost me in excess of 400 bucks

your vids are still tops mate ,welcome back

happy new yr mate and all tha best from australia

[AsktheBuilder]

Yep, that is a lot of money to a homeowner. It is great to be back. Happy New Year to you! I love my Australian friends and subscribers.

[Skunk980]

What if you wear a mask. please respond. thanks.

[AsktheBuilder]

Well, I guess that is fine if it is an approved mask, not one of those disposable paper ones. Read the Warning Labels on the cement-board products and see if you are willing to take that risk.

[Skunk980]

Tim, there is a special circular saw blade that has about 4 carbide teeth. It is ment to cut cement backer board, not an abrasive or diamond blade. please respond. Thanks

[AsktheBuilder]

Oh yes, there are any number of abrasive, diamond and carbide blades that will work. What you gain in speed and crispness of cut edge, you lose in dust generation. Don't forget that the dust from cement board contains silica which can cause silicosis.

[stubbadub81]

don't cut by hand if you have an angle grinder and a $10 diamond blade. the seems are flawless, it is the only way. lets see him cut around faucets without damaging the integrity of the cement board. this guy really isn't saving anybody from the pains of self defeat. just wear the safety gear and cut in the yard.

[AsktheBuilder]

Thanks for your comment. The trouble is, not every homeowner has an angle grinder stashed away in their basement or garage. Use a sharp one-half-inch cold chisel and a helping of patience to cut those faucet holes. How would you do it on your jobsite if you lost power? Surely you wouldn't call it a day.......

[viketaker]

yeah i like this method of cutting as opposed to saw cutting for STRAIGHT CUTS also. but, for L cuts or any non-continuous cuts im afraid a saw is in order.

[AsktheBuilder]

Not altogether true. An L-cut can be made without a saw. It is indeed faster with a saw, but can be done with a hammer, chisel and the scoring tool as showen above. Try to be more open-minded when you think of possible solutions. Also, why not tape a video showing your method?

[sisdavid]

It's for putting down for tile

[k45hiz]

What do you use this board for???

[AsktheBuilder]

Under wood stoves, behind wall tile, under floor tile, etc. The beauty in tile installations is it is 100% waterproof. Will never deteriorate. It is also fireproof.

[hammerofharpel]

Does that mean it contains asbestos? I suspect not but I want to ask for my own safety!

[AsktheBuilder]

Oh no! I can't think of any consumer product that contains asbestos. After all of those class-action lawsuits? No way.

[AsktheBuilder]

The reason you do not want to use a saw to cut the board is the dust. Silica dust absolutely is a carcinogen. Do NOT create dust when cutting concrete or cement.

[sisdavid]

It is for putting down before tile.

[slehvslehv]

thanx. that looks easy
