Sometimes creating mosaics on a surface that is convex or concave, upright or just not flat and level can be very challenging to say the least. But hang in there because the challenge is so worth the reward when your project is finished. Use these tips for apply mosaics to those pesky curved surfaces and you’ll find that those weird surfaces are no hassle at all.
• To make a piece of flat glass fit against a curved surface, nip the glass or tile into small pieces to conform to the curve. By using this technique you can apply glass or tile to almost any object, flat or curved.
• Use a bag of rice, dried beans or an old pillow to rest rounded objects on to prevent rolling during the mosaic process.
• Use thick multi-purpose adhesive or quick dry glue while you work on small areas at a time when adding tesserae to a curved surface to keep the pieces from sliding and to allow the area to dry faster.
• An alternative to the previous tip is to apply your mosaic piece to contact paper and then apply it to the curved surface after applying adhesive, if you are apply a mosaic to a vase or a similar cylindrical piece, tape the adjoining ends of contact paper to hold in place
•If the surface you are using is smooth or slick, try lightly sanding the surface. Wipe the surface with a lint free cloth to remove any dust or debris.
