dirty-concrete-6.jpg
2 MB,
Moving into a small industrial space to do some glass art and production. The easy answer for any other use of the space would be paint/vinyl garage floor style coverings. Can't do that though because if the glass falls on those types of coatings (glass hits the floor all the time) it will burn/fume.

The floor has seen many previous uses including automotive so there are motor oil splotches everywhere. It's been pressure washed by the landlord, but still looks pretty bad.

I'm going to try some dish-soap scrubbing and potentially bleach/H2O2 but don't want to ruin my chances of using some other sort of coating. (I've ready you shouldn't use acid cleaners if you're going to use and acid-stain, but don't know if that type would work in this situation)

So, does anyone know of:

- a non-flammable/meltable surface covering for floors?

- a way to renew large areas of concrete to like-new

- a stain that can take the heat and mask the other discolorations.

Thanks /diy

Is there some reason you're doing this other than aesthetic value?

As for solutions, maybe cover the floor surface of the work area with some heavy-duty plastic tarps, and then build some kind of clay or ceramic playform on top of that? It should be heat resistant enough, and you can just smash it up when you have to vacate the industrial space.

A pressure washer with medium (like sand stuff). it's like sand blasting the shit clean.

>>983124

That's the main reason, I'll be teaching classes and having customers come in who might be spending thousands of dollars (lets hope) on the shiny things I've made there. Presentation goes a long way to those types of people. If they think I'm slumming it in my workspace, they won't as easily be able to justify the cost.

>>983126

Thanks, I have a pressure washer, unsure if it's compatible with anything non-liquid, but I'll look into it.

Hey /diy/ I'm currently building a monitor arm out of an old IKEA Desklamp.

My plan was to get a cylinder the same diameter of the old lamp part so I can mount it the same, but where could I get a cylinder with a certain diameter from?

I want to increase my knowledge of chemistry. My high-school chemistry class was optional and now I regret not taking it. What are some experiments that could help me learn about different things chemistry related.
>inb4 thermite and gunpowder or anything related to ammonia or dangerous
Also it would be better if they don't require labs or very powerfull ovens.

First step on the road to chemistry is learning to make fluorine gas. After that you could try making chlorine tri fluoride.

DIY chemistry is not socially acceptable anymore. Most reactions are profoundly complex anyway so you'd be better off at least taking a community college run-down in the interest of not poisoning yourself or others but chances are you won't have access to chemicals or instruments anyway. If you don't have the drive to at least pick up a book concerning some particular reaction or any of the voluminous writings of chemists i wouldn't bother with any of the above.

get rid of all that shit before a dinosaur lays eggs in it. go buy a dozen or so concrete blocks and make a new u-shaped ring. dick it out so it's about 6" deep in the middle. depending on how much you use it the bricks will begin to crack so you'll have to spend a few bucks a year replacing the dead ones. you might want to make it a couple bricks high as well, up to you

What kind of tools do you have? Do you have an electric drill, a hand saw, a tape measure, screws, sandpaper, etc...? Do you have scrap wood lying around? I don't think it would be very comfortable to rest my hands on un-sanded plywood or MDF.

I am looking to get into screen printing so I can actually make money off my art.

What is the most cost effective screen printer that I could buy and what are some good guides to learn how to do it?

There is one on amazon that looks like a beginners kit for 99.99, but I don't know much about screen printing so I don't know if it is good.

Bet your art sucks.
>>
some stuff I found experimenting with t-shirt making

most cost effective screen printing is buy the screen material yourself and build a wooden frame from scrap wood .

you can buy stuff that you can paint your design onto the screen then cover whole screen with another type of solution which will turn your screen into a stencil . screen fluid?? something like that

discharge paste is interesting stuff, if you paint or print it onto black fabric allow to dry and then iron it will remove the colour from the fabric where you have painted . this can be useful for designs or you could for example lay loads of discharge paste on a t shirt and then print onto the lightened part with another colour .

if you do art have you come across " lino printing " ? this is where you carve a design into a piece of linoleum and then put ink on it and put onto paper . I did this in art class and it turns out you can use it on fabric pretty well . the good thing is that youre piece of lino is re usable so it may take time to make but it will last forever

think theres stuff on instructables as well . have fun
>>
The kit itself doesn't matter as much, you can even build one. The fact that the inks are nearly 30 per tub of quality is going to be costly depending on the complexity of your designs, so maybe stick to black or simple tones for now. Also how are you making your screens? Emulsion, modge podge, etc?

I'm looking to grow a few herbs and vegetables on my balcony, both to consume and to make the place look a bit better.

Should I go to the work of building a vertical garden or am I better off with just a small couple of grow beds?

Any tips or experiences you'd like to share?

>>>/out/743345

I found that with vertical growing you needed to compartmentalize the levels individually. You can't allow water to flow from the top to the bottom. Otherwise, it becomes very dry at the top and always soaking wet at the bottom. Keep the vertical distance of the soil to about 2.5-3 feet or less.

Before you go making too many beds on your balcony, you gotta understand that they are built to undergo a certain load, dirt, water, that shit is a heavy perminet load so you don't want to build anything that's too big, spreading it out so that some is on the wall in a vertical garden and having a few small planters on the balcony itself, just don't go overboard and have a full vegetable garden spread out over your entire balcony

What are you looking to do?

These look pretty dope already IMO, though you might want a handrail.

Carpeting onto concrete steps is pretty easy, there are adhesives and hardware made for it. People argue over which is more safe (carpeted or bare surface), but it's really personal preference.

Yeah, I'll definitely need handrails, but the staircase is pretty slim, so would need to be some smaller version.This is a fat shaming staircase.

Hey /diy/, I'm building an AR-15 lower out of an 80% receiver and need a few tools to do it.

First I need a drill press, I'd prefer to buy the cheapest one possible that will suit my needs as I have no other use for it. It needs to be able to drill through 7075 aluminum, the drill bits come with the kit so don't worry about those.

Second I need a router to finish it, also as cheap as possible while still being able to mill through 7075 aluminum, recommendations?

Thanks

Not sure if serious and just wanting a gun that isn't registered, or trolling, but the answer is at least a two parter. 1) If you use the cheapest tools, your results will look cheap. 2) Any drill press will handle the aluminum your talking about, haven't heard of using a router, though it might work; and to procure these el cheapo brand tools Google is your friend, friend.

You can rent tools these days, if you're going for cheapest method, look around at big hardware chain stores and see if they have the tools you need to rent, they can probably teach you how to use them too.
