CLEANING & PREPARATION
Surface preparation is by far the most important step
in your SpreadStone™ project. For optimum long–term
performance, the surface should be thoroughly
cleaned and dry, free from dust, dirt, loose flaking,
oils, poorly bonded or glossy paint, glue, surface
sealers, efflorescence and other contaminates.
APPLICATIONS OVER CONCRETE:
Surface should be level and in good condition. Chip away any loose or flaking concrete
and skim coat any rough or uneven areas with a quality leveling compound. Try to get
the surface fairly smooth to ensure that deep pitting, bumps and other
unsightly flaws do not transmit through your finish later. This is also the time to
mend any cracks in the concrete surface. These should be fixed with an appropriate crack
repair or cement patch product. If you have a troublesome, recurring crack in the surface
you may wish to look at the option of saw-cutting it relieve pressure in the slab. Hairline
cracks generally do not need to be repaired prior to application of SpreadStone™ if the
slab is stable. Allow all repair materials to cure as directed.
EXTERIOR CONCRETE PREPARATION
If the concrete is new, very smooth or efflorescent (whitish-colored mineral salts coming up
through the concrete surface) etching will be required. Otherwise this step can be optional.
Etching is a fairly simple process and only takes a few minutes to perform. To mix an
etching solution, first pour some water into a clean pail and, second, follow by adding
about half as much muriatic acid into the water (always in that order to avoid acid splashback)
and stir gently with a suitable mixing paddle. (Wear protective clothing, gloves
and eyewear and follow all safety precautions as provided by the muriatic
acid manufacturer. Avoid breathing vapors. Etching should be performed in a
1) Wet nearby soil, flowers and shrubs and other objects immediately prior to etching to
protect them from the etching process. 2) Carefully pour the mixture gently onto the entire
surface. Step away from the area to avoid breathing any vapors and allow it fizz for a few
minutes. 3) When fizzing stops, gently rinse away etching solution with a garden hose.
Washing is the most important step. You must remove all embedded dirt, dust and
powdery etching residue, etc. from the surface for reliable bond. For this stage
you must perform one or both of the following two options:
OPTION 1 - Using a stiff deck brush, vigorously scrub the area with a strong TSP (trisodium
phosphate) solution. If etching was performed previously, this is also helpful in neutralizing
any remaining acid residues. (If there are grease stains present, these should be washed
using a strong degreaser soap applied at 100% strength onto the grease spot, scrubbed
and thoroughly rinsed.) For most reliable cleaning, combine this step with
“Option 2” which follows.
Option 2 - (Recommended for best long-term durability) Use a power washer to
clean the concrete surface. For the most reliable cleaning this option is best. Use a unit
with at least 2400 psi pressure and clean the surface with slow sweeping movements
holding the spray tip about three inches from the surface. You will see a big difference in
cleanliness of the area using this method.
Allow a minimum 28 days cure before application.
NEW MASONRY COATINGS
Allow at least 48 hours cure before coating application. Longer in cool or damp conditions.
APPLICATIONS OVER WOOD
SpreadStone™ bonds well to wood. As with concrete, however, the wood must be clean,
stable and in good condition prior to application of your preferred coating. The surface to
be coated must be free from common and sanding dust, dirt and other contaminates
which may block or weaken adhesion. This is especially true with exterior decking surfaces
which are subject to precipitation and climactic changes. If a pre-existing paint coating is
on the surface, the following measures will apply:
If the paint is showing signs of weakness (peeling, flaking, bubbling, etc.) you should sand the
surface and remove it completely. Remove any sanding dust and/or paint debris with a vacuum
and follow with a wipe-down using a damp (not wet) sponge.
With the surface completely dry and clean, apply an “alkyd” wood primer. When the alkyd
primer has cured fully (see product directions) you may begin application of your SpreadStone™
If the painted surface is sound, scuff the entire painted surface with 140 grit sandpaper,
remove all sanding dust / debris and apply SpreadStone™ as desired.
If the floor is new construction, we recommend
that you use at least 5/8” tongue and groove
plywood fastened solidly to joists with galvanized
screws (for rust resistance).
Scuff the surface well with coarse grit
sandpaper to create a better bonding surface,
thoroughly vacuum the sanded area to remove
all resulting dust, coat the entire surface with a
quality alkyd primer and allow to cure fully.
Next, seams where plywood sheets meet
should be treated to help isolate movement as
1) Caulk all seams using paintable exterior grade
flexible acrylic caulking. 2) Push caulk into seams
and make flush with surface. 3) When caulking is
dry, apply a generous coat of DAICH Primer over the seam area. 4)
Embed fiber (drywall type) mesh into the wet material usuing your
fingers or a scraper. Use 2 to 3 staggered overlapping strips.
5) Finish with a final thin smoothing coat of DAICH Primer over the
mesh and allow to dry before continuing with general application.
Another option for isolating movement is applying a “mesh and
scratch coat.” This is a process by which a galvanized metal mesh
(lath) is stapled or nailed down to the existing primed plywood followed by application of
a polymer-enhanced masonry coating over the mesh/wood substrate until a smooth
surface is achieved. (Before performing this step we suggest you seek
knowledgeable detailed instruction from a qualified source.)
Wipe down the surface with a damp sponge to remove dust. If there is paint on the wall,
lightly scuff the surface with a medium to light grit sandpaper then vacuum or wipe off
sanding dust with a damp sponge.
Provided that the surface is not moving and structurally sound, laminates can provide an
acceptable substrate for SpreadStone™. As always, however, care must be taken to ensure
that movement does not occur where there are seams in the surface, which could result in
hairline cracking. To prepare a laminate surface for coating, the area should be thoroughly
scuffed with a course grit (40 to 60) sandpaper (to add good surface bonding tooth) and
then cleaned of all dust, dirt and sanding debris. Use this technique when preparing
for applications over laminate countertops as well.
Provided that the surface is not moving and structurally sound, interior vinyl flooring offers
an acceptable bonding substrate for SpreadStone™ To prepare a vinyl surface for coating,
the area should be thoroughly scuffed with a course grit sandpaper (to add good surface
bonding tooth) and then cleaned of all dust, dirt and sanding debris. If installing over
vinyl tile, it’s important to ensure that the tiles are firmly adhered to a stable
floor with little or no movement to ensure that hairline cracks do not appear
where tiles meet. Otherwise, measures will have to be taken to eliminate
INTERIOR CERAMIC TILE
Provided that the surface is clean, dust-free, not moving and structurally sound, interior
ceramic tile can provide an acceptable bonding surface.
If the tile has a shiny, high-slip veneer, it should be removed through surface abrasion or
with an “etching” product that can be used to remove the shine.
Next, scrub the surface thoroughly with a strong TSP solution, rinse thoroughly until
clean and allow to dry fully. If adequate drainage is not available, a wet/dry vacuum will be
necessary to lift water and debris from the surface. If you wish to conceal the old grout
lines, you will need to fill them with a suitable masonry material to create a uniform
surface prior to application of SpreadStone™.
Alternatively, you can apply a suitable masonry skim coat over the entire cleaned area
to add a completely new and porous application surface.
*Floor movement stabilization/isolation methods mentioned here are only suggestions toward achieving correct
surface conditions prior to application and are not a guarantee as to final results.We recommend that you seek
additional expert advice and choose the best preparation strategies based on your specific situation.
SpreadStone’s versatility lets you experiment with a variety of techniques to
achieve just the right combination of texture and color - and create a look that
suits your unique taste.
The most common application tool used is a steel trowel - which we will
outline here - but you can also try tools like brushes, standard and textured
rollers, sea sponges, brooms, etc.
With SpreadStone you can go with a one-color application and rely on the
interplay of texture and shadow to complete your finish - or blend a variety of
When applying multiple colors, the technique employed is generally “wet-inwet,”
in which varying tones are mixed together directly on the application
surface as you move along, to produce interesting marbling effects and attractive
intermediate tones. The darkest and/or strongest colors are often applied first as a
thin base coat, followed by lighter “mix colors” to produce a sense of depth in
Remember: these are just guidelines. Feel free to experiment and find ways to
create your own unique effect.

Daich Coatings dealer for a copy of our instructional video or view it online at
TYPICAL TROWEL APPLICATION
1) Stir SpreadStone thoroughly prior to
application 2) Stir SpreadStone tinted to your
preferred base color and, in manageable areas
within your reach, apply a thin layer of the
material over the surface (no more than 1/16”
thick) with a straight-edged steel trowel.
3) Next, lightly skim your highlight colors into
the wet surface as desired, taking care not to
overmix them into the base and lose your
preferred tones. Vary the degree of mixing -
more in some places, less or not at all, in
others. 4) On vertical surfaces a plastering
“hawk” can be used to limit spillage during application. Pull
product in an upward motion. 5) With colors mixed to your
liking, add a stipple texture to the surface by lightly patting it
with the flat side of your trowel or a large damp sea sponge.
6) Next, with the smoother tool that came with your
SpreadStone, lightly skim over and randomly “knock down” the
tips of the stippled surface. This action will dictate the degree of
final texture in your SpreadStone finish. The more you knock it
down, the smoother and more marbelized it will be. 7) For
increased or more rapid texture smoothing, or to slow drying
time, use a spray bottle to lightly mist SpreadStone with water
just prior to “knock-down” 8) For best control and longer
working time, do not apply under hot sunlight. 9)Work
temperature should be between 5º C and 40º C during
installation and for a full 24 hours after application. In outdoor
applications, SpreadStone is usually dry to the touch within 60 minutes (3 to 4
hours indoors). When complete, allow curing for 24 hours - longer in damp, cool
or unventilated conditions - prior to sealing.
TILE & FLAGSTONE EFFECTS
1) If using a patterned tile or flagstone effect for your finish, begin by troweling a
thin skim coat of SpreadStone tinted to your desired grout color over the entire
area (between 1/32” to 1/16” thickness). This first coat is also a very effective
surface “primer.” Allow it to cure until the next day - unless you are working
outdoors in windy, dry and warm conditions which may speed drying
considerably. 2) Using tape as a stencil, tape out a groutline pattern in your
preferred tile or stone size and pattern over the dry base coat. For typical tile
effects, use 1/4” Daich Coatings “Tile Grout Tape.” For flagstone effects, use duct
tape and trim away the straight edges with a utility knife for an irregular
“natural” appearance. 3) Carefully apply SpreadStone in your desired finish over
the taped surface. Take care not to dislodge your tape stencil as you
move along. As a precaution, you may wish to brush on a very thin coat of
base-colored SpreadStone over the stencil lines to “tack” them down before
general application. This light application usually dries very quickly and should not
delay your work. 4) Apply SpreadStone to your liking and, when it has cured for
24 hours, peel up your stencil to reveal your grout pattern.
Sponging offers a great way to accentuate the texture in your
SpreadStone finish, while very effectively camouflaging any
areas that may not look exactly as you had planned. It also
adds more visual depth while giving you the opportunity of introducing “clean”
(unmixed) highlight colors. 1) Apply SpreadStone in your preferred color onto a
large sponge. 2) With varying hand pressure, randomly drag the sponge across
the textured SpreadStone surface and highlight to your liking. It is best to begin
with lighter pressure when your sponge is freshly loaded to avoid applying too
much color in one place. Sponging should be performed before grout stencils are
Tint washes also effectively accent surface texture, but will not
hide imperfect application like sponging can. Tint washes can
also create beautiful translucent effects when applied over
white or lightly colored SpreadStone textured surfaces.
1) Mix one tablespoon of DAICH powdered tint with between
2 and 4 quarts of water as desired. Stir until uniform. 2) Distribute the mixture
randomly over your dry SpreadStone surface using a sponge or string mop, and
allow to dry fully. Perform tinting before grout line stencils are removed.
Sanding is an effective option for refining the overall surface appearance and
texture after SpreadStone™ has dried fully - especially with interior applications.
It removes unwanted rough spots and can lend a more blended appearance.
When performed after tint washing, sanding also has the interesting effect of
“shaving” off part of the tinted finish and re-exposing the original color in the
surface for a rustic highlight.
1) Use 80 or 100 grit sandpaper mounted on a pole sander and draw it
uniformly over the dried installation surface area. 2) Remove all sanding dust and
debris before application of sealer.
** Avoid breathing sanding dust. To perform sanding, use a quality
fitted NIOSH-approved dustmask (N-95 rating or better) when sanding
and for removing resulting dust. If vacuming, use a unit equipped with
a filter rated for use with fine particulates).
SpreadStone™ can also be applied to floor and wall surfaces using an air
powered hopper pistol assembly. Product can be sprayed in a uniform stipple
pattern and knocked down for partial smoothing and attractive textural designs.
Alternately, SpreadStone™ can be sprayed in a light speckled pattern over a
basecoat to create a granite-like or terrazzo appearance. Experiment to refine your
technique before doing an actual installation and see what you can achieve!
With your SpreadStone™ installation completed and cured, its time to roll on a
protective coating of sealer to help keep it clean and water-resistant.
Two sealers can be used with SpreadStone™: ”Acrylic Sealer” and “High-Build
A) For most exterior installations where a more textured, matte finish is desired,
choose Acrylic Sealer.
B) For interior floors, shower areas, garage floors, countertops and higher-traffic
exterior surfaces subject to more dirt, High-Build Clear is best. It effectively fills
deep surface texture with a clear acrylic film that helps block dirt intrusion into the
finish for easiest cleaning where rain, garden hoses and power washers are not
availailable or suitable. Multiple coats can be applied (24 hours between coats -
longer in cooler weather) as desired until your preferred degree of smoothness and
cleanability is achieved. ** IF YOUR GOAL IS A VERY SMOOTH SURFACE, DO NOT
RELY SOLELY ON MULTIPLE COATS OF HIGH-BUILD CLEAR. SPREADSTONE™
SHOULD BE APPLIED MORE SMOOTHLY BEFOREHAND - OR AT LEAST SANDED TO
YOUR PREFERRED SMOOTHNESS IF THE SURFACE WAS ALLOWED TO DRY WITH
**REMEMBER: As surface smoothness is increased, slip resistance and
resulting foot traction decreases.**
With your surface prepared, you are ready to unlock your
creative taste with SpreadStone. Using the following
directions – and a bit of practice – you should soon be
achieving beautiful results.
APPLYING ACRYLIC SEALER
1) In clean footwear, sweep or wipe away any dirt or foreign objects
that may be on your new SpreadStone™ surface (leaves, bird
droppings, etc.). 2) Pour Acrylic Sealer into a paint tray and apply a
uniform coat onto the entire area using a lint-free 10 mm nap roller.
Apply a second coat 24 to 48 hours later. 3) Avoid stepping
on the surface while it is tacky. 4) Rope off the sealed area to allow
curing and discourage foot traffic for 24 hours. 5)Wash the surface,
allow it to dry and re-seal the following year.Afterward, sealing every
one or two years is adequate for ongoing maintenance.
APPLYING HIGH-BUILD CLEAR
1) Sweep or wipe away any dirt or foreign objects that may be on your new
SpreadStone™ surface. 2) Pour High-Build Clear into a paint tray and apply a
generous uniform coat onto the entire area using a lint-free 10 mm nap roller or
paint brush. First coats usually show significant absorbtion.
Greater film build will occur with coats that follow. Apply
additional coats every 18 - 24 hours (longer in damp or
cool conditions) until desired result is achieved. (Surface
may be used between coats provided that the area is kept
clean.) 3) Do not step on the surface while it is tacky. 4)
Rope off the area to allow curing and discourage foot
traffic for 24 hours.
