These tiles are an excellent solution to cover up a grotty ceiling without a lot of elbow grease. Easy and quick to install with the added benefit of an instant result. I did consider painting them with a DTM paint but ended up using a clear lacquer which I'm glad I did because it really brought out the detail on the tiles. I had no problems installing the tiles, I was able to use thin nails because the tiles are so lightweight and tin snips to make any cuts. Be warned the edges are really sharp so wear work gloves. Great quality, Great product.
