We seal our Slimtek products with resin creating a seamless, 100% waterproof finish to our signs. Our Acrylic letters with embedded LEDs are absolutely maintenance free! Once installed, the sign is protected against natural hazards and does not require any monitoring, maintenance or cleaning. It is our attention to detail which won our products a UL certificate.

It is also important to know that each Kalisign illuminated sign comes with its Meanwell brand IP65* rated transformer. It is 100% waterproof and air-proof therefore it can be used for outdoor use without concern of deterioration.

*IP65 standard: "total protection against dust and water jets from all directions at the lance (22.5 mm nozzle, 12.5 l / min)."
