Hi does any GFRC Spray Gun Hopper would work thanks

[brofun]

also..how thick is the finished product? What size fibers are used? thanks..

[lookatmyconcrete]

@brofun The thickness of the product and size of the fibers can vary depending on the project. We have made concrete as thin as a half inch. Our countertops are usually 1 inch thick.

[lookatmyconcrete]

@lookatmyconcrete I'm sorry, our countertops are typically 1.5 inches thick.

[brofun]

did you spray that on a styrofoam base?..or was that a mold that you would remove later? I do vertical concrete and overlays..and would love to learn more about hits..can it be sprayed over existing formica tops?

thanks

[lookatmyconcrete]

@brofun In this video, we sprayed over a mold that is removed after curing. The mix design that we spray is only a decorative facial coat that is non structural. Without the fiber backing it is easily cracked. There are other products on the market for vertical and overlays.

[brofun]

@lookatmyconcrete  ok..I think I understand that..the decorative spray goes down real smooth..then the fiber cement is packed behind it to give it rigidity..is that correct? I have a couple of bathroom vanities that I want to make into gfrc tops. Any other tips are more than welcome!! Thanks.

The mesh used is the same that is used for stucco applications, correct?

[lookatmyconcrete]

@gluemanred No, a GFRC material manufacturere or supplier has all of the materials needed.

Thanks so much! I will be starting my concrete countertops this summer (living in WA state, have to wait until the weather warms up a bit, LOL) -

[lookatmyconcrete]

@pamgotcher If you are not a concrete countertop manufacturer, I do not reccomend GFRC countertops for a home improvement project. It often takes many years to develop usable techniques and mix design.

[pamgotcher]

@lookatmyconcrete Thanks! The thing that was most interesting to me re: the build here was the mesh application. I used a polyesther reinforcing fiber in my bottle wall inserts, and know that it does take some working -

[pamgotcher]

What were you spraying on the mold before you did the press work? Was it color or a mold release?

[lookatmyconcrete]

@pamgotcher The spray is actually a concrete mix that is very similar to the backers but it is lacking chopped fiber.

can you send me the video to omal69@hotmail.com

adn you let me know isf is any fiber i can use or is a special thanks

[lookatmyconcrete]

@omal69 Fiber used in GFRC should be AR (alkaline resistant) chopped fiber.
