CT Presoak GEL



Gelled Concrete Truck Wash Presoak

Description and Use

CT Presoak Gel is the first step of a two step application process for the removal of heavy excess concrete from concrete mixer trucks and construction equipment. CT Presoak Gel is designed to be a presoak concrete softener before applying the second step product called CT Wash. CT Wash breaks the bond between the softened concrete and the surface.

Power penetration and softening action.

Do not allow a prolonged dwell time on glass.

General Preparation
Protect adjacent and surrounding surfaces not intended to be cleaned when necessary.

Surface and Air Temperatures
Excessively high or low temperatures will produce poor results and possible harm. Best cleaning results are obtained when air and surface temperatures are 40° Fahrenheit or above. Do not clean when temperatures are below freezing or will be overnight. If freezing conditions exist, allow adequate time for surface to thaw. If air temperatures exceed 90° Fahrenheit, flash cool the surface with water before applying product. Do not allow products to dry on the surface. Always rinse thoroughly while still wet.

Always test prior to beginning full-scale cleaning operations. Testing should confirm cleaning effectiveness on each type of surface and stain designated to be removed. Testing also determines the desired dwell time and any potential for adverse reactions with adjacent materials. Allow test panels to dry thoroughly before evaluating final appearance and results.

- Use CT Presoak Gel undiluted (straight)
- 4:1 for removing heavy build-up
- Follow with CT Wash straight - 4:1


General Application
Apply the product undiluted via sprayer directly on the areas of heavy excess concrete. (An EC Jet can be used when using a 4:1 dilution). After a soak time of one hour at 50ºF or higher, apply CT Wash without rinsing. Use one or two applications at a 4:1 dilution and allow to dwell for a minimum five minutes per application. Craftsmanship determines the appropriate pressures for rinsing. A thorough rinse job is always recommended, however, our chemistry never requires flooding a wall. Pressures that mark or damage the surface should be avoided. When in doubt, follow the manufacturers recommended P.S.I. for the substrate on which you are working.
