health issue-acid stain-infloor heating
hallo
i have to combine in floor heating system with acid stain concrete and i need to know any health contraindications because of any chemical or other particals that can harm the health ( inhale or what any components)...and if i have to use for sealing water based sealer
thanks
hallo
thanks for the response
i'm meaning the sealers/coatings, overlayments if can harm our health because of possible??/ swinging particles that spread in the room??
I'm sorry, but I am just not following you line of thought .... "swinging particles" (what?)

If an overlay is to be applied they are liquid polymer into a modified cementious materials, or water into a dry mix that has dried polymers alreay incorporated into it ... either a self-leveling micro-topping is then floated out or an overlayment is troweled in place (but again, unless they are being mixed indoors there is nothing that is a particle that will be floating out in the air.

As for stains and sealers ...this is to "infinite" of generic terms due to there being different formulas, components, types, etc. ... some are environmentally friendly and classified as non-hazardous, others are not ... again, you need to be more specific.

For actual factual information suggest you acquire the manufacturers Technical Data/Specifiction Sheets for all materials that are being considered for use ... read them, along with the Material Safety Data Sheets for the individualized materials.

Person probably had asthma or some respiratory illness and is concerned about particulate becoming entrained in the air as a result of thermal activity in the floor. After the instalation of the decorative treatment including the sealer, all components become unreactive to a conventional heating system. There should not be any issues to worry about except the normal day to day dust in the air. I came across a client who was paranoid about any residue from the toppings that dripped into the furnace heating duct. She had them tested for "contaminants" and found none. Her fears were for the health of a baby with serious health problems. She thought the topping material might be triggered by the furnace heat. Strange.
Any industrial product used inside a home presents some health concerns during the installation. After the installation however, there should be no health concerns whatsoever.
Overlays: They come in powder form and need to mixed with liquids. During the mixing dust will be generated and cover adjacent areas. Easy remedy is to do all the mixing outside of the home so there is no dust brought in.
Acid Stains and sealers come in liquid form, typically the contractor will protect all areas that will not be treated with stain or sealer. After the installation there should be no areas with stain or sealer residue left.
Some sealers are solvent based and have very strong smell and /or irritating vapors, some acid stains have very strong acid odor as well. Proper ventilation during and after application is necessary to ensure there is not fumes left in.

Many manufacturing product used inside a home presents some health concerns during the installation but don't worry because the contractor will protect all areas that will not be treated with stain or sealer. After the installation there should be no areas with stain or sealer remains left.
Living in Nebraska I have done a ton of these. I have never had any issues and I sealed with various solvent based sealers.
I did however have an issue when one of the kids' sawcut control joints too deep and when tubes were pressure tested fluid shot up from 4 different places........ He did not work for me much longer!!!!!
There is one sure thing in this business ... unforeseen problems can, and will, occur, with hindsight being 20-20 vision. I feel your agony as to the spewing up/out of water.
One of my personal "dah" moments came on a exterior patio (house had walls on 2 sides, no cover, and mulberry trees that had badly stained the concrete over the years). I had sealed it with an aliphatic urethane (they take hours longer to dry than a PAP which takes only 30 minutes to an 1 hour to dry/cure). They took their dogs to a relatives house while work was being done and everyone knew to "stay off the patio" until the job was completed in order to deter any type of accidental incidents. I failed to notice a dryer vent that blows out the side of the house over the patio ... while the aliphatic urethane was drying they did some laundry ...I'm sure you can guess what happened 
... an area about 5' long and 3-4' wide had a substantial amount of dryer lint (that was being blown out of the vent) stuck all over the urethane sealed surface (so much of it that you could hardy see the color of the decorative concrete surface beneath it. The lint was well bonded down into the urethane 
and took a lot of tedious work to sand off the lint without damaging the decorative concrete surface beneath it. Word of warning ... if you are ever working on a patio that has a dryer vent that will blow out over it make sure you tell the homeowner to NOT use the dryer while there is anything that is not dry/cured (be it overlayments, stain/dyes, sealers/coatings, etc.) or you will be in the same boat.

Are you asking if the reative acid staining process itself it hazardous in some way until which time it has dried (ie: air contamination/fuming/etc) ... or, are you referring the the types of sealers that environmently safe to be applied over them (in reference to solvent free, meeting the criteria of the USDA & FDA). I'm not understanding as to what radiant heat has to do with your question; however, various types of decorative concrete, sealers/coatings, overlayments & microctopping, etc are applied over radiant heat floors (being either the pipe type that are incorporated when the concete is poured/finished) or within cementitous polymer modified cementitous overlayments (either the wire or mesh heating type). Can you please explain your question or concern in a little further detail.
