    Can I use Seal-Krete Original All-Purpose Waterproofer on the exterior of my home before repainting? The stucco is chalking and I want to ensure that the paint properly adheres to the stucco.

    Seal-Krete Original is an excellent primer/sealer when repainting both residential and commercial properties. It binds chalky surfaces and can be applied over oil-based, as well as water-based paints and coatings. Seal-Krete Original can also be added to water-based paints to improve the spread rate. It contains a high quality resin and improves the quality of the paint. Four to eight ounces per gallon is recommended when mixed with the topcoat of paint.

    I’m the president of the Historic Committee in my community and we’re looking to preserve several of the original brick buildings in the downtown area. Some of the bricks are crumbling due to moisture over the years. Can we use Seal-Krete Original All-Purpose Waterproofer to preserve these important landmarks?

    Yes. Seal-Krete Original has been used for more than 25 years to protect and preserve America’s landmarks. The buildings should be properly cleaned and free of any efflorescence before sealing. Fragile, loose, and missing mortar joints will require tuck pointing prior to application of Seal-Krete Original.
