"Used 25 Ltrs of this product so far. Have found the quality to be consistent throughout. Covers well even over previously treated surfaces. It is however easy to overspray if you are unfamiliar with spraying techniques. The best advice I could give to avoid over spraying an area is to do it in several light coats. Takes a little longer but better results. The product comes in 5Ltr Plastic containers a handy size and just the right amount for use with the Ronseal Spayer. Easy to shake to make sure it is well mixed and easy to pour into the sprayer. Overall very satisfied with this product."
