Your little house tile sign has been made using a commercial grade UV print technology designed to provide a durable lasting print. Our tiles are mounted in custom made galvanised or powdercoated steel frame also designed to keep its condition outside. It is important however to ensure that the sign is kept away from harsh chemicals or abrasives. If your number requires cleaning, simply wipe gently with a clean damp cloth. If you have any questions or concerns regarding cleaning please reach out to us here so that we can provide support and direction.
