The Karcher RM 542 Outdoor Surface Protector is a 1 litre ready-to-use spray impregnator. It is made for patios, decking, stone and other outdoor surfaces. Use it after you clean with your pressure washer. Clean surfaces take the treatment best.
It forms a durable protective layer. The layer guards the surface against weathering, dirt and moisture. It also has a colour refreshing formula. That restores the natural look of established patios, stone paths and timber decking.
The formula uses 99.9% natural ingredients. The bottle is 100% recycled plastic. So it suits contractors and property maintenance teams who want an eco-conscious product. The spray format keeps the job simple on small areas.
Why buy it? Cleaning only gets you so far, because a bare surface soon picks up dirt again. A protective coat slows that cycle. Pick it if you have just washed a patio or deck and want the finish to last. Follow the label for coverage and drying times.
