  • Vinegar Cleaning Grout Haze and Pit Stains

    Vinegar Cleaning Grout Haze and Pit Stains

    Glass mosaic tile, particularly vitreous glass tiles have sometimes have a few tiny pits in their surface, and these tiny pits can get stained with grout. Fortunately the pit staining can be prevented by applying a product called grout release before grouting, which is what installers use for large architectural tiling jobs. You can also…

  • Grout Line as Design and Figurative Element

    Grout Line as Design and Figurative Element

    Natalija Moss’s latest Honda Insight mosaic is a great example of stained-glass mosaic where the grout line is used as a figurative element and as an element visual framing. Natalija is a self-taught artist and mosaicist just like me, and she also rebuilds Honda Insights by restoring interiors and rebuilding the battery system with newer…

  • Grouting Dorothy’s Spider Web Mosaic

    Grouting Dorothy’s Spider Web Mosaic

    Artist Dorothy Stucki made a fast-motion video of the process of grouting her mosaic Goddess in the House of Night, from dumping on the wet grout to buffing and hazing. The grouting video is on Dorothy’s Instagram. Dorothy’s mosaic is a spider web complete with spider and ensnared moths and insects.

  • Case Study: Non-Sanded Grout for Mosaics with Incidental Gap

    Case Study: Non-Sanded Grout for Mosaics with Incidental Gap

    For better glass mosaic images, tiny incidental gaps are the way to go. Just forget about grouting and fit the glass as tightly as possible. Or better yet, cut the pieces less precisely and use the slight errors in shapes to form an incidental grout gap. I highly recommend this latter mode of working because…

  • Nonstandard Method for Removing Mortar in Gaps

    Nonstandard Method for Removing Mortar in Gaps

    Natalija reminded me that she used her cordless drill with a mesh disc to remove the hardened mortar, and that cordless rechargeable tools exist. Either we didn’t have cordless rechargeable tools on my home planet, or I was having a stress-induced boomer episode yesterday. One of those two things is true, maybe both.

  • White Grout: The Floral Print Aesthetic

    White Grout: The Floral Print Aesthetic

    Artist Masha Leder‘s mixed pique-assiette architectural mosaics using white grout are so good I wanted to name this blog article “In Praise of White Grout.” I have been hoping more people would email me some photos of their white-grout mosaic artwork ever since I started posting about avoiding white grout in mosaic images, meaning figurative…

  • Imperfection as Grout Gap

    Imperfection as Grout Gap

    The Blue Crab mosaic I recently completed is a good example of how to create a grout gap by making use of imperfect cuts instead of spacing the tiles intentionally. The “imperfect cut” method makes the process of creating a mosaic faster, easier, and less tedious -first in the cutting and placing of tiles but…

  • Choosing Grout Color Using Tile Test Swatches

    Choosing Grout Color Using Tile Test Swatches

    Tracy Kaplan recently emailed us a picture of her FIRST mosaic, and it is nice solid work, impressive even, especially considering that her instructor gave her some problematic advice concerning the grout color.  Tracy’s teacher had recommended a chocolate or nutmeg colored grout, but Tracy wisely considered how a dark brown might cause adjacent tree…

  • Staining Grout With Acrylic Paint

    Staining Grout With Acrylic Paint

    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…

  • Consistent Grout Gaps

    Consistent Grout Gaps

    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…

  • Black Grout vs White Grout

    Black Grout vs White Grout

    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…

  • Grouting Case Study (Plus Mosaic Art Worth Seeing)

    Grouting Case Study (Plus Mosaic Art Worth Seeing)

    Artist Sherri Grasmuck created a mosaic facade of Guatemalan women on her house in Philadelphia that is the perfect case study for choosing a grout color.
