CTi Frequently Asked Questions
How does CTi provide protection from stains, oil spills, salt?
Once the skim coat is troweled on and the colored decorative coat is sprayed, the surface is sealed with an acrylic sealer. This sealer is non-porous and UV protective.
Is there any effect of cold weather when installing the CTi?
No, because there is no water used in the process and the polymer dries in approximately 60 minutes. To speed up the drying process in colder weather heaters are used to warm the surface.
Will cold weather affect CTi?
This CTi system was ASTM tested by subjecting it to a 60 day freeze thaw cycle. This means that it was frozen and thawed 60 consecutive times with no adverse effect. It is stronger and denser than standard concrete and will hold up to cold weather much longer.
Will my concrete still heave in the winter?
Concrete heaving cannot be eliminated. However, once your existing concrete is surfaced with CTi, the Surface will be denser and less porous. Less water will be retained by the concrete and therefore, lessen the effects of the freeze thaw cycle.
How thick is it applied?
The thinner we can apply the mixture the better. Usually between 3/32" to 1/8". The skim coat can be applied up to 2" thick to fill in low areas, level areas, and fill holes. Areas that require fill greater than 2" can be filled with a portland cement gravel mix over a coat of epoxy prior to the skim coat application.
How does the product bond with existing concrete?
We acid etch and power wash the existing concrete to clean off dirt, remove loose aggregate and open the pores. Next, a hand troweled skim coat of polymer and portland cement is applied to the surface as thin as possible. This allows maximum absorption of the polymer into the existing concrete. When the polymer dries it becomes part of the existing concrete because the polymer is absorbed and dries as part of the old surface. The polymer strengthens and makes the existing concrete more dense as the new application and old surface become an integrated piece.
How long has the CTi product been in use?
The CTi manufacturing facility has been producing resurfacing products since 1968. Acrylic resurfacing has been in use since the early 70's. A polymer was added to the process in the 80's to provide a superior bonding process to add strength.
What is the CTi Concrete System?
The CTi Concrete System is a color integrated, modified acrylic polymer, mixed with portland cement that is activated with a modified acrylic resin.
