If you're thinking of using Recycled Blocks to save money you want to keep in mind that the old blocks need to be cleaned, sanded and are often not equal in size, making fitting time longer. Not all adhesives will accept the black bitumen that is present on most blocks. We have a special technique for fitting such blocks. You may not save money due the extra work involved and materials. However, old blocks can mean a rich finish as older wood was grown and managed quite differently than today's timber. It is also quite possible to find blocks made from timber that are not available today, such as exotic red woods or English Oak. It is recommended to seek professional advice on such projects.
