FAQ
What is acrylic?+
Acrylic, also known as PMMA (Polymethyl Methacrylate), is a durable thermoplastic polymer. It’s prized for its clarity, strength, and weather resistance – making it ideal for outdoor use.
How do I clean my acrylic letterbox/house number?+
Use a soft cloth dampened with warm soapy water. Avoid abrasive cleaners or scouring pads which can scratch the surface. Dry immediately to prevent watermarks.
Is acrylic weather resistant?+
Yes, acrylic is naturally quite weather-resistant. However, prolonged exposure to direct sunlight and extreme temperatures can cause some fading over time. Regular cleaning helps maintain its appearance.
Can I paint my acrylic letterbox/house number?+
Acrylic itself is difficult to paint directly. It’s recommended to prime the surface with a suitable primer designed for plastics before applying your chosen paint. Ensure the paint is specifically formulated for outdoor use and UV resistance.
How secure are acrylic letterboxes?+
While acrylic is durable, it's not as inherently strong as metal. Consider installing a robust locking mechanism or reinforcing the base for added security against theft.
What size range do these acrylic letterboxes/house numbers come in?+
Sizes vary across individual listings, but you’ll typically find options ranging from standard UK postcode sizes to larger house number formats. Check each product description for precise dimensions.
Are the acrylic letters and numbers UV resistant?+
The acrylic itself is naturally UV resistant, however, over extended periods of direct sunlight exposure, fading may occur. Regular cleaning will help minimise this effect.
What tools are needed to install these letterboxes?+
Installation typically involves drilling a hole in your wall and securing the letterbox using appropriate fixings (not supplied). A drill, screwdriver, and level are usually sufficient.
How do I choose the right size for my house number?+
Measure the width of your property’s address line. Add approximately 5mm to this measurement to ensure a comfortable fit. Consider the font style and spacing when selecting your desired number size.
Are these acrylic letterboxes suitable for exposed locations?+
Yes, they are designed for outdoor use and can withstand exposure to rain, wind, and sunlight. However, we recommend regular cleaning to maintain their appearance and prevent weathering damage.
