DESCRIPTION: A pre-blended product that can be used on existing concrete surfaces.
This material is placed approximately 3/8” thick and imprinted with a mat type tool to create
impressions such as stone, brick, tile, or other authentic type surfaces. This product can
be used on exterior floors, driveways, patios, pool decks, and other surfaces for vehicular
and pedestrian traffic.

Surface Preparation: All surfaces shall be clean and free of dirt, dust, paint, sealers,
form releases, curing agents, grease, oil, or any inhibiting mixed material that would
impede the penetration of Unipas Polymer to the substrate pores. Any material that would
cause de-lamination must be removed. Pressure washing, sand blasting, water blasting,
grinding & shot blasting are suggested procedures for removing contaminants from the
surface. On existing surfaces not subject to these conditions, pressure washing and 30
parts water to 1 part acid should be considered for smooth, steel troweled, or formed

Mixing & Application:

1. Bonding Primer: Begin with a properly prepared Saturated Surface Dry substrate.
Apply Concrete Colors Unipas Polymer undiluted over saturated substrate. Scrub
polymer into the surface with a medium to stiff broom or brush. Make sure to
cover all areas that will be receiving the stampable overlay mixture. Allow this
primer to dry to a clear film. Do not walk on the dried primer unless the use of
proper footwear that will not tear the film from the concrete has been attained.
Suggested footwear, rubber spikes.

2. Depending on the desired application, the addition of water and Unipas polymer
is as follows, add 2.5-3 quarts of clean potable water and 2.5-3 quarts of Unipas
polymer to a 50lb bag of Concrete Colors overlayment. Slowly add the 50lb.
mixture of overlayment to the water / Unipas combination and mix for approx. 3
to 4 minutes, until a lump free consistency has been obtained. Place material onto
the surface and screed with a gauge rake set to the desired thickness. Smooth out
material with a fresno, or hand held pool trowels to consolidate the material.
Allow the material to gain sufficient structural integrity to accept imprinting tools for impression work or for smooth trowel if desired.
For imprinted work, a powder release agent or liquid release agent can be used.
After imprinting or other surface textures have been completed, allow 4-7 days for curing

• Do not allow the Unipas Polymer mixture to freeze.

• Apply between the temperatures of 60 – 100 degrees Fahrenheit.

• Allow 4-7 days of curing before opening to vehicular traffic.

• Keep installed material from freezing for a minimum of 48 hours.
