2430 Ulster Flex (10% & 20%)

2430 Ulster Flex is a breathable, low odor, solvent-based, clear, custom blended silicone elastomer for use on most vertical masonry surfaces. 2430's highly UV stable formula provides long lasting protection from acid rain deterioration, minimizes freeze/thaw damage and remains flexible during periods of masonry expansion and contraction. Ulster Flex also makes graffiti removal easier when surfaces are defaced with paints, spray paint, lipstick, crayon and most other commonly used materials.

2431 Ulster Flex is to be used on split face hollow core concrete block only. This higher solids formula creates a hydrophobic barrier, within the block pores, with the same flexible material as the 2430. Due to the different methods used in the manufacture of split face hollow core block, some surfaces may require two coats to effect a weatherproof condition when exposed to wind driven rain. It is recommended that all split face concrete block be tested with one or two applications prior to the start of a project.

Preparation & Application

Protect all non masonry surfaces from dripping or over spray. Provide protection for windows, foliage, adjacent surfaces that are not to receive treatment, vehicle and pedestrian traffic. Take precautions to protect other surfaces from wind drift. Using the method to be used on the project, apply a test area of 10 square feet to calculate the coverage rate per gallon and to determine if there will be any unacceptable color change. For most dense masonry, coverage rates should be between 75 to 125 square feet per gallon. For split face hollow core concrete block the coverage should be between 50 and 100 square feet per gallon. All masonry surfaces should be clean, surface and subsurface dry prior to application. A spray application is preferred but roller applications can be successful as long as there is complete surface saturation. Spray equipment must be clean and equipped with solvent resistant hoses and gaskets. Apply with a coarse low pressure spray creating a saturating 4 to 6 inch run down of the fluid.

Limitations

All masonry surfaces must be free of any agent or agents that will prevent penetration of the fluid. Application should not be undertaken when rain is eminent within 12 hours or if there is frost or ice in the surface. The best results are obtained when surface and ambient temperatures are 40 degrees and rising. Do not alter the product with any other material. Ulster Flex products are not acceptable for application to horizontal, polished masonry and granite surfaces. If the fluid comes in contact with window glass or other non masonry surfaces, remove immediately with a solvent soaked rag. Ulster Flex applications may cause a slight to moderate color enhancement of some surfaces. Testing is recommended, prior to the start of a project, to determine if there are any changes that are unacceptable.
