Mosaicists sometimes mix in artist acrylic paint to create custom colors from white grout, but you can also use acrylic paint to “stain” grout after it has hardened (for dry indoor mosaics).
Like the process of staining wood, “staining” grout with paint is a process of wiping on and wiping off. The paint sticks to the rough grout but wipes off the glass tile. Continue reading
In my recent blog article about black and white grout, I wrote the following tip for minimizing the width of grout gaps and working a little faster at the same time:
If tiles only touch at points but not along the length of their sides, then tiles can be positioned very closely and yet still be grouted. Consider working in this way instead of carefully cutting each tile to maintain a uniform grout gap.
I need to clarify what I meant by that.
Uniform Versus Consistent
Sometimes novice mosaicists will carefully cut each tile to maintain a perfectly uniform gap, which can be a little tedious, and worse yet, they make the gap a little wider than it should be because the artist does not have the experience to visualize what it will look like when grouted.
I think it is better to work a little less uniform, and to err on the side of being slightly narrow, even if that means tiles occasionally touch at a point or corner. By better, I mean more efficient, less tedious, and better looking.
All that being said, it is extremely important that the mosaic have the same type of grout gap in all regions. You want to be consistent in your style of gap. You do not want to have loosely executed in one place and tightly uniform in another, nor do you want wide gaps in one region and narrow gaps in another. Continue reading
You can increase visual interest in your mosaic by using variegated colors (multiple colors in patches or streaks) instead of monochromatic fields of only one color. This technique is particularly effective if your design is relatively simple and made from outlined areas of color like a coloring book or cartoon. Continue reading
Black grouts bring out the intensity of tile colors while white grouts overwhelm them. Natalie Knox’s Day of the Dead Skull mosaic is a good example of how well black grouts work and how a light colored backer isn’t a good indicator of the mosaic would look with white grout.
Don’t Be Fooled
If you lay the mosaic out on a white backer and try to use that as an indication of what the mosaic will look like with white grout, remember this:
When the gaps are filled with grout, they won’t have all the contrast provided by empty gaps, which have depth and shadow. A lot of white concrete at the same level as the surface of the glass tends to make the colors look washed out. Continue reading
Outdoor mosaics must be made on concrete or stone or masonry, but that doesn’t mean you have to pour a concrete slab or do some other form of heavy construction.
Flagstones (flat paving stones) and concrete stepping stones are readily available at building material stores and lawn and garden centers. The flagstones are great if you want a natural irregular shapes, and the molded stepping stones are great for square and rectangular shapes.
Of course, thinset mortar must be used to attach the tiles, but that isn’t difficult to do, especially if you lay your mosaic up in advance on mosaic mounting tape or mounting paper.
If that seems complicated, it isn’t. I wrote some instructions for using packing tape and contact paper to lay up a mosaic design.
The last section of this article explains why you shouldn’t use plywood, Hardibacker, or (sometimes) even concrete backer board. Continue reading
Artist Risa Puno recently completed her interactive mosaic sculpture Common Ground for Rufus King Park in Jamaica Queens, NYC, and the project is a great example for discussing materials and methods for mosaic table tops.
No Plywood Backers Outdoors
Plywood is never an acceptable backer for outdoor mosaic table tops.
Humidity in outdoor air can cause plywood to swell, contract, and warp, and even if the displacement is too small to be noticed, it can still cause grout to crack and tiles to pop off. Once grout has hairline cracks, moisture can penetrate underneath, and then there isn’t any hope for the mosaic lasting after that happens.
If you have a wooden table that you want to mosaic for outdoors, then attach a piece of 1/4-inch concrete backer board over the top of the wood and mosaic on that.
Seal your finished outdoor mosaic with a tile and grout sealer and reseal it each fall. Silicone-based gout sealers are wipe-on-wipe-off and easy to apply. Most of the work is buffing off the excess so that the surfaces are slippery. Continue reading
The Mosaic Art Supply warehouse is filled with artist studios in appropriated spaces: the loading dock, the office, the reception area, and mixed-use tables in the middle of the warehouse itself.
In my most recent blog post, I discussed how purchases from Mosaic Art Supply support the arts in a real and direct way. In this blog article, I wanted to show pictures of some of the studio areas in our warehouse. Continue reading
Employees at Mosaic Art Supply are emerging artists actively pursuing their passions.
Support the Arts in a Real Way
Every purchase you make from us supports the arts in a real and direct way, perhaps more so than any donation you could make to an arts related charity or foundation. For starters, we don’t have grossly overpaid directors from the patrician class, and we pay our employees as much as we can afford. More than we can afford actually, but not what they are worth.
Unlike a lot of charities and foundations with overpaid directors, we have never had any unpaid interns.
Artist Angela Bortone
Angela Bortone is a painter, video artist and art writer. She mixes other people’s voices into her paintings and videos. Born in the Dominican Republic, Bortone was raised in Brooklyn and spent nearly a decade abroad in Germany before moving to Atlanta in 2002. She earned a BFA in studio art from Georgia State University in 2010.
Inspiring mosaic table tops with abstract geometric patterns were recently created by artist Risa Puno as part of her public art project Common Ground, an interactive sculpture designed to bring people closer together physically.
The concept of Risa’s sculpture plays on the metaphor of multiculturalism as mosaic, but instead of the folk or children’s artwork usually associated with that theme , there are cleaner abstract designs with color choices that ensure that each table has similar levels of intensity and contrast. The result is that the combined “quilt” is balanced and unified visually. Continue reading
Keira Miller recently made a mosaic bench in the shape of the state of California with a class of 4th, 5th, and 6th graders. The mosaic bench is made from California redwood and is to be auctioned off as part of a fundraiser to benefit their Montessori school.
Note that we do NOT recommend wood as a backer for outdoor mosaics, but if this mosaic had to be placed outdoors, some of the drier regions of California would be ideal. I think the mosaic would do well on a covered porch, and it would be a great addition to a family room or den. Continue reading
