Stripping observatory concrete floor?
heat gun...
"Richard DeLuca" wrote in message news Hi, Is there an EASY way of stripping latex paint completely off my concrete observatory floor? Right now, I'm using Strip-Ease, and that's a real pain, and will take a couple of days (100 square feet). Then I'll have to rinse the floor with water and then lightly sandpaper. Then I'll start over, but this time with something other than latex. I'm pretty sure I asked for concrete floor paint back then, but it was ten years ago and I'm not sure. Over the years it has bubbled, peeled, and has 'sticky' spots. Any suggestions for a good paint for the floor of a roll-off in the Northeast? Thanks for any help! Starry Skies, Rich |

Starry Skies, Rich Lateral thinking: Cork or ceramic tiles or (clip together) parquet flooring? Floating floor of T&G plywood or chipboard (particle board) would be cheaper. All except the ceramic would be warmer and more comfortable underfoot but prone to moisture. How about AstroTurf? How about carpet? You like cement/ concrete? Self levelling compound on top of what you've got. Chris.B |

Stripping observatory concrete floor?
Cathy wrote in message ...
The stain I mention is a *solid* color latex stain. Its thin, yet creamy and covers quite nicely with a roller. Ive used it over latex paint on wood railings and I have stained already treated and painted decks, already painted concrete patios. It holds up quite well to foot traffic. The first treatment at my home was over older, never done anything to it, concrete. I had a small problem on the porch where water stands, as the original application of the stain bubbled up and started peeling. A quick blast with the power washer to remove the flaking latex stain and I was able to stain right over it... and it holds up, for a year or two, but, I am always going to have the problem of standing water there and this problem will repeat itself. Oh well, another spring chore! Richard DeLuca wrote: Cathy, I'm not clear on what a stain looks like, and whether I can use it on previously painted concrete. Did you put it on a previously painted surface (after stripping) or was this the first treatment on new concrete? ,,,,,,,,,Rich I work Commerical Const. after you strip the floor use one part muratic acid,three parts water to "etch" the floor, before applying epoxy floor paint or stain. We always etch new or old concrete. The stain will be uneven if the floor isn't uniformly clean. I recommend the epoxy floor paint. The epoxy is very violate to breath, but it's the most durable to wear. DL Smallen |

Stripping observatory concrete floor?
Three thoughts.
1. Why paint the floor? There are concrete sealers, similar to the masonry sealers used to seal masonry joints after tuck-pointing. As I understand it, this is the floor on a roll-off. Thus, the floor is covered and is not exposed to the weather -- unless you are in the habit of rolling the cover off during a rainstorm -- which is not healthy for the scope. :-) So, why paint the floor at all? What's wrong with a nice concrete floor? 2. If you need to paint it, look into an epoxy products; as I recall, they come in a few stock colors and can be tinted. Most popular use for these epoxy paints is on the concrete block walls inside schools where they provide a durable surface that washes off readily. Pay attention to the instructions when you apply the epoxy-based coating -- because you are applying only to a small floor, not to 30,000 square feet of vertical surface, should go on easily. 3. I'll bet you put the current coating on when the concrete was new. New concrete is subject to "efflorescence" that goes on for some time -- months to years after finishing. Efflorescence is the chemical process of moisture seeping through the concrete, leaching out the alkaline salts in the concrete, and floating those salts to the surface where they form a fine coating. Take a look at a sheltered concrete wall -- basement walls are good places for this -- that was poured a few months ago -- see the patches of white stuff? Wipe your hand over it then slightly moisten your hand. It burns. Because this is a strong alkali that has leached out of the concrete. And it is death on paint. Back when I was painting part-time, I would get a call from a homeowner whose new home had poured concrete basement walls. First thing he did upon moving in was paint the walls. Now, 12 months later, the paint is stripping off. The only thing to do was strip it -- various commercial strippers take it off -- scrub the wall, tell the homeowner about efflorescence, and tell him to leave the wall alone for another 12 months until the chemistry of the concrete has settled down. Because your concrete is old, you should not have this problem. Before you apply the new paint, the concrete MUST BE BONE DRY AND CLEAN. Do whatever you can do to dry it -- may want to leave the door open, set up a big fan at the end opposite the door, and let it run for a few days to dry it. Finally, go to a REAL PAINT STORE -- one where the professional painters in your area shop. Talk to them. You may also want to browse the web for "painting concrete," "concrete paint," or similar phrases. Just a few thoughts. -- ---- "Richard DeLuca" wrote in message news Hi, Is there an EASY way of stripping latex paint completely off my concrete observatory floor?

Check it out:
http://www.amerimexpaints.com/html/concrete_floors.html http://www.concretenetwork.com/concr...e/painting.htm http://www.vogelpaint.com/PaintingConcrete.html Read the section on new coating -- they recommend a specific type of epoxy coating. In their section on stripping the old paint, they mention "abrasive removal" SANDBLASTING the old paint off -- is that an option for you? You could rent a sandblaster and abrasive. -- ---- "Richard DeLuca" wrote in message news Hi, Is there an EASY way of stripping latex paint completely off my concrete observatory floor?
