Treatex Hardwax Oil ULTRA Clear Natural - Stair Parts


Protect and enhance the natural beauty of wood with Treatex Hardwax Oil ULTRA. Using over 40 years of experience in the timber and wood finishing industries our Hardwax Oil ULTRA was developed to be user friendly, quick drying, easy to maintain but above all to provide a hard wearing and attractive finish. Treatex Hardwax Oil ULTRA is manufactured on a base of natural sustainable raw materials: jojoba oil, linseed oil, sunflower oil, beeswax, candelilla wax and carnauba wax. Suitable for all types of internal joinery including floors, stairs, doors, furniture and kitchen worktops.

    Can’t fault the service at all, always on time and reliable. Deliveries are always well communicated. I had a little issue this morning, the driver waited 10 minutes for me, helped unload. One of the few suppliers that make our job easier. Thanks guys

  • Catherine Booth Catherine Booth – in the last week

    We have ordered 2 sets of staircases from Stairbox. We liked the first one so much and the customer service and delivery were excellent so we decided to order a second. Once again the product, service and delivery were excellent. I would highly recommend this company.

    Carl Mason came and delivered our order. Unfortunately I was in a meeting and wasn’t able to help him with unloading etc. Carl very kindly unloaded everything and put it when I requested. He was very friendly and professional and it wasn’t a issue that I wasn’t able to help. Would definitely recommend
