I recently used the Valspar waterproof cement sealant to seal the cement in my backyard I recently had refinished. I purchased a 5 gallon bucket at my local Lowes store.
I thought since I purchased the product at Lowes that it would be a quality high end product. I followed the directions on the bucket, but the product failed miserably and did not seal my cement at all. I subsequently have waterstains all over my backyard patio.
I now believe I have not only wasted money on a defective Valsper product, but since the product failed to work properly I may have to spend thousands more getting my cement patio stripped of the Valsper sealant as well as getting it refinished.
