<DIV><FONT size=2 face=Arial>I have been told by numerous concrete contractors
that after the stain, a sealer is always applied--one of several possible types.
Then a layer of wax may be applied, as that provides a scuff or scratch layer.
But without exception, everyone told me after staining, they apply a sealer
before any possible wax.</FONT></DIV>

<DIV><BR></DIV>I don't understand why anyone would seal the stained floors.
Waxing is so much nicer, it gives a beautiful warm glow. I did my floors ten
years ago, waxed them
<DIV>and was told to wax them every year, did that once but have never

<DIV><FONT size=2 face=Arial>What do you mean "the concrete was never acid

staining before sealing other than waiting a few days. What is the etching
that should have been done--how is it done, etc.? This could be useful in
further documenting the problems (since ultimately the contractor IS going

<DIV><FONT size=2 face=Arial>Also can you explain more about shot blasting?
You say it's more cost-effective, but how does it compare to grinding as far
as time involved, how much it's going to totally mess up my house, etc.? No
one's mentioned this yet but it sounds like something I should look into,
especially since sealer removal will be required whether I go with more
concrete staining or with tile (or something else I haven't yet considered).

<DIV><BR></DIV><FONT face=Arial><SPAN style="FONT-SIZE: 12px">Non-acid
stains like soy stains or polymer stains only sit on the surface and in
some of the macro-pores of the concrete. Acid stain works by
chemically reacting with the free lime in the concrete and the salts in
the stain, to physically alter the chemistry of the concrete, thus
changing the color. The white you see could be a white base stain,
or, it could be that the concrete was never acid etched before using the
sealer. Acid etching removes the “cream” off the surface of the
concrete. This is the fine white or grey powder that will eventually
dust off the surface. Without removing the cream, any coating or
topical stain will eventually peel off the surface, since its only
sticking to dust. <BR><BR>Grinding and shot blasting are two
different ways to achieve the same end result. It its a large area,
shot blasting will be more cost effective and will require less prep
before the next coating is applied.<BR><BR><BR>Andrew Pace<BR>Green Design

<BLOCKQUOTE><FONT face=Arial><SPAN style="FONT-SIZE: 12px">I have been
told water-based stain--which was used to get the mottled creative
pattern that was intended (without white blooms)--does not sink into the
concrete like acid-stain does. Either way, where the stain and sealer
have pulled up, there's plain white. It's chalky. Numerous concrete
contractors had no idea what that was, telling me my contractor must
have done a white layer of stain first, which I knew was not the case.
One finally pointed out it's calcium carbonate that chemically reacted
to something (the diesel/propane fuel? the exterior stain that was used
indoors [as I later found out]?) That makes sense to me as one gets
white on the finger when rubbing those areas. The white areas are all
white--the stain has completely lifted up. So it does not seem to have
gone down into the concrete--unless there is more under the calcium
carbonate.<BR> <BR>Also I should have mentioned earlier much of the
sealer seems to have disappeared. When put down it was very shiny (as it
was supposed to remain) but now in many areas there appears to be little
or no sealer (this is from work done two months ago), and one contractor
commented the sealer is soft (vs. it supposedly the hardest, most
durable there is per my contractor who clearly misled me in numerous
ways).<BR> <BR>Per the sealer tech rep, the sealer does need to be
removed whether I go with concrete again or with tile. He seems to lean
towards grinding to remove it. Is that the same as the shot blast you
mention?<BR></SPAN></FONT></BLOCKQUOTE>
