After Care
About Oak
Wood is a natural material that naturally responds to changes in temperature and humidity by expanding and contracting. While these shifts are typically minor, you may notice small hairline cracks over time—this is a natural characteristic that adds to the wood’s unique charm. Seasonal changes can also cause slight movement in the timber, which is completely normal and expected as part of its aging process.
After Care
Regular care is essential to keep your product in top condition. We recommend treating the wood with Danish oil or a similar timber treatment to nourish and protect it. This helps prevent drying out, discoloration, staining, cracking, and warping, ensuring its longevity and beauty over time.

FAQ's
Can I approve my design before you begin engraving?
Absolutely! We’ll never engrave anything until you’ve confirmed the design. After your order, we’ll email you design options for approval. Feel free to share any preferences, and we’ll refine the design until you’re completely happy. No engraving will take place until you give the final confirmation.
How do I choose my font?
We can engrave nearly any font. We’ll provide a range of font options for you to choose from. If you have a specific font in mind, just mention it in the additional instructions, and we’ll include it. You can also let us know your style preferences, and we’ll tailor the choices accordingly. If you’re unsure, we’ll still provide a variety for you to pick from.
How do I choose the colour for my engraving?
Choosing an engraving colour comes down to both aesthetic preference and how the product will be used.
- White offers the highest contrast, making it ideal for clear visibility.
- Black is a more traditional option that still provides strong contrast.
- Natural / unpainted engravings suit interior and household décor items best, rather than signage.
- Reflective paint has a subtle silver tone and contains light-reflecting pigments, giving it the best visibility at night. This works best with bolder fonts, which will be reflected in the available design options.
You can read more about reflective finishes in our blog post.
If you have a custom colour in mind, please get in touch — we’re always happy to source a specific finish for you.
How do I add a logo or emblem to my order?
Once your order is placed, we’ll be in touch shortly via email to discuss your design. However, it’s very helpful if you can email your logo or emblem to us as soon as possible so it can be included in the initial design concepts.
Please send your image to info@graindesigns.com.
If your emblem or logo is particularly detailed or intricate, there is a chance it may not translate fully when engraved. In these cases, we recommend emailing it to us before placing your order — we’re happy to review it and provide proofs so you can be confident the final result meets your expectations.
What if I’d like different dimensions or a design that isn’t shown in the listing?
No problem at all — many of our products are made completely to order. Whether you’re looking for different dimensions or have a fully custom design in mind, we’d love to hear your ideas.
You’re welcome to explore our Inspiration page and existing product range for ideas, then get in touch to tell us what you’re looking for. We’ll be happy to help refine your concept and bring it to life.
How long does production and delivery take?
Our standard build time is 8–15 working days, depending on current demand. The most up-to-date lead times are always shown in our Shipping Policy.
If you need your order sooner, you can select Express Delivery at checkout for priority production. Once dispatched, delivery typically takes 1–2 working days.
