We respectfully request that this information be
Required Reading for Homeowners,
Business owners, Builders and Subcontractor for the
concrete slabs we are asked to stain.
Concrete
Stained Floor Requirements
1.
The finished outcome of a concrete stained floor
or concrete overlay floor is directly the result of the care
and responsibility taken by the builder and subcontractor that
work on the slab before the arrival of the concrete straining
crews. As our crews cannot be onsite to ensure the care of the
concrete floor it should be covered during the entire
construction process.
We recommend that the slab not be covered with
plastic after the pour is made as this will leave some
very interesting marks in the slab that are not very
appealing (or maybe they are). Masonite or plywood can be
used until the slab is “dried in” and then two layers of
roofing (heavy gauge rosin paper) paper can be used for
the duration of the construction process provided that
the subcontractors are all informed not to spill
adhesives, paints, solvents, oils, varnishes or stains on
the slab. Ha-Ha, what a joke cover the floor thoroughly,
nobody cares
about your floor except you, trust
me.
A.
If this is new construction here are the
instructions for the concrete to be poured:
1. A quality batch of concrete should consist of
at least a 5 sack mix with no fly ash, retarders or
chloride accelerators. The slab should be lightly power
troweled to give a slick finish without creating too many
“burns” in the concrete surface. This will give you a
beautiful look and at the same time ensure that the
concrete is readily stainable. The concrete should be wet
cured using curing blankets for at least 7 days while
keeping the concrete at all times wet during those 7days.
ABSOLUTELY NO CURING COMPOUNDS ARE TO BE USED! The use of
curing compounds will result in a slab that is either
impossible or very difficult to stain and will be a very
large additional cost to remove.
The paper should be
taped together and the tape should not be applied
to the concrete floor for any reason. This will act as a
barrier (stain resist) to the stain when applied.
The mistaken
spilling of the contaminants will just add to the cost of
the staining process because these are very hard if not
impossible to remove and are not very attractive if
exposed during the staining process.
The concrete floors are to be clean swept and
removed of all building materials, furniture, equipment,
and fixtures and the paper covering the floor. Our fees
do not include the removal of these items and fees will
be assessed for us to remove them. Sorry our insurance
does not cover these items.
2.
If the above listed procedures are not adhered
to the stains, chips in the concrete floor and imperfections
will all be readily apparent but fear not sometimes but not
always these all add character to the slab and of course we are
after an aged mottled “old world” look so this may just add to
the character.
3.
That being said the Owners, Builders, and
subcontractors are solely responsible for the condition of the
concrete floor prior to our crews commencing work. No liability
is accepted or implied on our part for the condition of the
floor. We insist that all parties listed above take
responsibility for the floor prior to our arrival. A copy of
these instructions should be given to the GC and all the subs
and make them sign off on having received them. That way when
you back charge them for possible additional charges from us or
other contractors they can’t say “We didn’t
know”.
4.
We use extended release tapes and plastics to
mask the baseboards and the walls. We do not however accept
responsibility for paint peel off during the removal of the
plastic and tape at the end of the process. Staining is an
extremely wet process and as such water and stained water can
make their way under tape and onto baseboards and trim.
Builder’s grade paint is very often what we would consider
below grade and often does not stand up to these
conditions.
5.
Anything that will not allow the stain to come
in contact with the concrete surface is what we refer to as a
“resist”. All glues, adhesives, pipe dope, sealers including
curing agents etc. fall into this category. For instance your
painter has taped his plastic or drop cloth to the floor and
when pulls up the tape it leaves behind an adhesive residue,
Yes I am repeating
myself it is that important. This will cause the stain to
show the tape spot on the floor and take the stain differently
in that area.
6.
If your plumber puts in a sprinkler system or
regular plumbing and drips pipe dope on the floor you will see
those spots as well. If the painter doesn’t cover the floor
well and the overspray of the paint gets on the floor it may
show as well even though it appears all the paint has been
removed.
If you are going to cover your floors with paper
make sure to use at least builder’s grade paper and at
best rosin paper that can be found in the roofing dept.
Tape the paper to itself and DO NOT TAPE IT TO THE FLOOR
(repeating
again). Overlap the paper approximately 4 inches and
that should give you good coverage. Most large rolls of
paper come with about 432 sq. ft. of coverage with
overlap you can figure around 350-375 sq. ft. coverage
per roll. I would also recommend you place cardboard or
Masonite on top of the paper. Do not use plastic as this
will not let the concrete “breath”.
If you want a beautiful concrete floor this is a
small expense to consider when you live with these
beautiful floors for at least a few years. Take the time
to do this step and it will pay dividends beyond the
small amount of time and money it takes to do
it.
7.
Heavy furniture can scratch the surface
especially if you might have nails where your pads might have
previously been located on the bottom of the legs so be sure to
check. We recommend felt pads, magic movers or similar items
which are durable and relatively inexpensive.
8.
Your concrete stained floor needs to be vacuumed
or dust mopped periodically and an occasional damp mop using a
neutral cleaner which can be purchased at Home Depot. That is
all that is required to maintain your floor. You will need to
apply a floor finish 1-2 times a year which will take 15
minutes and 30 minutes to dry. Compare that to 4-6 times a year
to clean your carpet. A Swiffer works great!
9.
The staining process requires running water,
preferably an outside faucet and two 110 volt outlets. The
electrical outlets need to be within 200 ft. of the furthest
point of the slab where we will be staining.
10.
Our prices are based the actual square
footage of the building. Just as an architect, designer
or appraiser would measure, wall to wall, that is how we
measure. Why do we measure this way, in short we have to
tape off all the walls within that area and that is a lot
of extra work.
11.
Our prices do not include excessive
cleaning of the concrete floor, protective covering of
the slab upon completion, post construction cleaning or
any other service not listed on our Estimate/Proposal. We
do everything in our power to create beautiful and
cost-effective floors and a little assistance from
yourself and the GC goes a long way.
12.
We fully expect to have to do a little
touch-up here and there. We will schedule that upon
completion. There is no charge for minor touchups but
there will be a charge if there are areas that we have to
totally redo due to abuse from other
contractors.
13.
For floors that have been completed in an
overlay all of the above conditions apply. In addition an
extra day or two should be given before heavy traffic is
allowed on the floor.
14.
Scheduling is critical to our performance
and the outcome of your project. Please contact us 3-4
weeks in advance in the fall and winter and 5-6 weeks in
advance during the spring and summer. We want to make
sure that we have enough time to give your project the
attention it deserves so we ask to be notified well in
advance of your project.
We realize that project scheduling changes as
projects changes, especially with commercial projects, we
just want to be kept in the loop so we can make sure we
have an adequate amount of time to complete your project
as well as our other clients.
15.
After completion and inspection of the
concrete stained floor it is the responsibility of the
homeowner, business owner, general contractor and/or
builder to protect the stained concrete or concrete
overlay floor.
16.
Concrete acid stains and pigmented stains
react chemically with the free lime in the concrete or
overlay. Concrete acid stain color charts will show what
the typical concrete slab or concrete overlay will render
but due to the differences in concrete slabs from company
to company and area of the country, concrete slab colors
may vary. This is why it is best to do a sample on the
concrete slab itself.
It is a little different with a concrete
overlay. You first of all with get a more consistent
color and this color will be more vivid and in most cases
more dramatic. This is because the mix is consistent and
we are using white Portland cement in the mix as opposed
to grey Portland cement in normal concrete.
17.
These are a few contractor mistakes that
we cannot remedy in most cases so be sure to make all of
your contractors are aware of these
conditions.
·
Contractors normally use Sharpies or Marks-a-Lot
permanent ink markers – These are an ABSOLUTE
NO-NO!!!
·
Electricians normally use spray paint to mark
areas where outlets will go-this paint does not come easily or
sometimes at all
·
Sheetrock and drywall contractor are notorious
for making the biggest mess and for some unknown reason they
expect everyone else to clean up after them-WE WON’T so get
them to cover your floors
·
Painters are kind of like drywallers they spray
their paint pretty much wherever they want and when they roll
they’re not much better, you need to tell them to cover the
floor or they won’t. If they are spraying the cabinets with
urethane or varnish it will get on the floor also – Again ask
them to cover up the floor.
·
Carpenters like to use red caulk for their caulk
lines- ask them to use orange
·
Plumbers that are installing sprinkler system in
commercial spaces will use oil to cut the pipes and when they
install them they drip that oily water on the concrete which
will leave a stain, they’ll tell you it won’t but trust me it
will. Also the pipe solvent they use is clear and won’t show
until the floor is stained and then there is nothing that can
be done about it.
·
Concrete contractors use curing agents on the
concrete to hold in moisture during the hydration
process(curing process) these curing agents block the stain’s
penetration into the concrete- WET CURE THE CONCRETE - DO NOT
USE CURING AGENTS
18.
Remodeling Projects-
Many folks want to rip up their carpets and tile and
linoleum and think they can just stain the concrete-It’s
just not that easy. Under your carpet, tile or what ever
are a bunch of potential problems that just might not let
you stain the concrete. This is sometimes when an overlay
might be the answer to the question.
A.
Carpet or Tile- When removing you can be face
with two possible problems
1.
Tacks strips are sometimes used to hold down
your carpet in this case when you pull up the tack strip you
will create holes in the concrete because the tack strips are
nailed into the concrete and they always pull up a little
concrete when you rip them out.
2.
Carpet adhesive may have been used on the floor
for your carpet or the padding or indoor-outdoor carpet which
was very popular in the past. In the case of concrete staining
all of this material will need to be removed. We manufacture a
carpet adhesive remover called Glu-B-Gone which works extremely
well for this situation. A razor scraper in 4” or 8” will come
in handy for this situation.
Even in the case of great adhesive removal you
may be left with a bit of residue in the pores of the
concrete. This may not be visible until you stain the
concrete floors. You just need to be aware of this
condition when you make your decision between stained
concrete floors and stained concrete overlays.
3. VCT tile glue can
be dealt with in the manner described above
for
carpet adhesive removal. You may need to use a different
adhesive
remover such as Twin-Chemicals Stick-M-Up water based
adhesive
remover.
4.
Porcelain or ceramic tile is a whole different
ball game. When you remove the tile you are left with the grid
marks of the tile where it has stained the concrete. It other
words the grout for the tile has allowed all the materials that
stained it through to the concrete. You are left with a surface
that can be “stained” but you will see the grid on the
concrete. There are specific faux techniques to take your eye
away from the grid, but the marks will remain. To date we have
never found any cleaning agent that would completely remove the
grid. Our Dyna Blue (mild acidic detergent) can sometimes
remove up to 75% of the grid but not always.
In this case a concrete overlay is a great
alternative to concrete staining. You can create any look
you want and contrary to what many “concrete stainers”
say overlays can be troweled just as smooth as concrete
and will allow for the “aged marble effect” you may be
looking for. You can even get a
textured concrete floor with an overlay which you cannot
do with concrete.
5.
Older Concrete Floors- Many warehouses that have
been converted to lofts and many old residences have concrete
that is 30-40-50 years and older. The concrete may have lost a
lot of the free lime from the surface (which is what the metal
salts in the stain react with) and may not be a good candidate
for concrete floor staining.
While tests can be done
on the concrete to determine the viability of staining
for that surface many times an overlay can be used in
this situation. If you are bound and determined to stain
the concrete you have there are products such Scofield’s
“Enhancer” which can add some of the ingredients
necessary to stain back into the concrete. This can work
on some concrete slabs but not all.
6.
Paint Overspray- While this is definitely a
project stopper in the case of a stained concrete floor, the
project can be saved when using and overlay. You will of course
need to remove all the paint and we will use a liquid polymer
on the concrete to ensure adhesion.
7.
Exteriors- Concrete that has been poured at
different times can render different hues of stain color even
when sprayed at the same times. This is because concrete coming
from different companies has different ingredients such as the
amount of fly ash dissimilar brands of Portland cement and so
forth. You can even have different ingredients coming from the
same company at different times of the year.
We hope this “Required Reading” has given you
some insights into the possibilities and even some of the
limitations of concrete floor staining and the advantages
of concrete overlay when concrete staining is not the
right fit. Yes I do realize that I have repeated myself
about several things within this document, they are that
important to the success of your project.
You can still have your stained floors in the
case of concrete overlays but there are several
surprising things you will find with concrete overlay
floors; the floors are warmer on your feet than tile, you
will get brighter and more vivid colors with the overlay,
you can have textured floors which resemble stone or
marble, are much less expensive and require a heck of a
lot less maintenance than real marble.
