After putting it down on outdoor concrete how soon must I have tile installed

Asked by Jaysl November 12, 2020
1
Answer

If tile or stone will not be set immediately after curing, protect the membrane from rain, inclement weather and potential construction traffic damage. If delays longer than 72 hours are expected, cover and protect the membrane from extended direct sunlight (UV exposure). For further assistance please contact us at 1 800 282 8786 option 2.

Can you used red guard on a fiber glass shower?

Answers

This is applied over cement board prior to mortar/tile. If your fiberglass shower is cracked, they sell patch repair epoxy. Red guard dries red in color. Not for use on a fiber glass shower.

I would feel safe to say about 40sq feet, per gallon, I did a 200sq foot room with 5 gallons, but I also pre-taped some cracks with fiberglass mesh, using this as the "MUD"...

Yes the product is designed specifically to handle and seal most surfaces including plywood, drywall and concrete. For 1500 SF coverage I would not worry about expansion joints other than securing tile with edge gaps of 3/4 of an inch. I have installed large format ceramic and porcelain tile with hydronic heat coils 4 years ago and it is still nice and solid. It is not cheap but good stuff.

I usually buy the large bucket, I can get three showers with two coats out of that

getting ready to lay a laminate flooring can i apply this to the concrete for the moisture barrier instead of plastic

Asked by Billy August 14, 2020

Answers

I guess you could use this under laminate flooring to block moisture but it seems like overkill sicne the advantage of this product is that it is thick and allows relative movement (shearing) between under payment and flooring to prevent cracking of brittle materials like tile.

Can this product be laid down directly over old durable flowing or do i need to use a primer first. Also, can self leveling concrete be applied?

Asked by Ray July 28, 2020

Answers

I used this product on concrete floors, Hardy/cement board , and sheet rock without any problems. I'm sure self leveling concrete will not be a problem. I used it in shower enclosures, shower and tub floors before tile installation. Use plenty ventilation the product is very strong. Good luck

what is the spread rate of the red guard?

Asked by alma July 20, 2020
2
Answers

I'm not sure exactly what you mean. From my limited experience with it (one bathroom) I can tell you that it dries pretty quickly. You're not going to be able to "work it" like you can with grout or mastic. Two or three minutes after it's spread it starts to congeal, and while you can scrape it off for a few minutes after that, you can't smooth it out. Think of it as fast drying paint and you'll be OK.

Is there a solvent or someway to get this off of wood?

RedGard Waterproofing and Crack Prevention Mortar will soften with a solvent-based paint stripper. For further assistance please contact us at 1 800 282 8786 option 2.

Like Drylock, this stuff goes on heavy, and you want to put on two coats. It is definitely superior to Drylock, however. If you are doing basement walls and floors, like me, remember to brush all the loose dust away first (with a broom). And you'll want to get a brush to fill in wider cracks, and/or deeper divots, that a paint roller just can't get into. Expect that you will lose your paint roller, because this stuff seals up very tacky! Also, the fumes are pretty intense. I recommend doing this when the weather is nice, and you can open up windows.

Worked perfectly. Applied to the bathroom plywood sub-floor in mobile home. Once product has dried (turns red and there is NO question is dry), we applied self stick tiles. Small gaps filled and there are no air pockets...perfect. We thought the product was too expensive. However, when purchased in the 3.5 gal size, the price was very comparable to most primers/sealers.

RedGuard, the new hot mopping. If you can paint, you can apply RedGuard yourself. Actually, it's easier than painting since you don't have to care about how pretty it looks. We used 4 coats total for 2 bathrooms and haven't had any problems with it, but of course, only time will tell. It dries pretty quickly so we applied the 2nd coat within a few hours. 1 layer for crack prevention and 2 layers for waterproofing. It is a little expensive but you can do it same day vs scheduling with a hot mopper(it's smelly, too). It does dry and harden around the container so keep it clean and don't let it fall in the bucket.
