Hardboard tends to make a good foundation for your mosaics as extended as you restrict the dimensions of the general mosaic, limit the tesserae dimension, and do not screen the mosaic in a moist atmosphere. Stay away from hardboard for outdoor purposes because of the possible for deterioration. Assuming your tesserae are the measurement of a quarter or less and the all round size of your mosaic is less than 24″x24″, I have identified that one/8-inch thick hardboard provides an satisfactory foundation. If your tesserae are modest, it’s stunning how versatile the mosaic is, even with grout, which indicates it can face up to some warping ahead of the grout cracks or glass parts pop off. If your tesserae are big or if you include massive items of stained glass into your mosaic, the thickness of your foundation need to be higher simply because the mosaic are unable to endure as considerably warping (i.e., the thicker the wooden, the a lot more resistant to warping). For case in point, suppose your mosaic is 24″x24″ and you use a single piece of yellow stained glass to signify the vibrant sunshine lighting up the entire world. Suppose the sun’s diameter is ten inches, which can make up a good chunk of the mosaic. It is easy to see how a small warping can pressure that solitary piece of glass creating failure (i.e., breaking, popping off). It truly is like ceramic tile on a concrete-slab basis. As the concrete cracks and moves, pressure is applied to the ceramic tile and, if the tension is wonderful enough, the tile breaks. Consequently, you need to think about the tesserae dimension when picking the thickness of your mosaic’s foundation.
Over the several years creating many wall mosaics that are 24″x24″ or considerably less, I have found that my favored foundation is 1/8-inch hardboard. It is the dim-brown things that pegboard is manufactured from but without having the holes. It truly is slippery sleek on one aspect and tough on the other. I use this materials only for dry, indoor, wall mosaics that will not be exposed to dampness. I use this content because it is: one) Relatively slim, two) Fairly lightweight, and three) Rough on one aspect so the glue grabs keep of it properly.
The 1/eight-inch thickness permits the concluded mosaic to in shape in a common pre-manufactured frame. My glass tesserae are about one/eight-inch thick, so the overall thickness of the concluded mosaic is only about one/4-inch. This allows me to acquire a completely ready-made frame for virtually absolutely nothing. I strategy my indoor wall mosaics to be sixteen”x24″, eighteen”x24″, or 24″x24″, which are frequent sizes for pre-manufactured frames. If I ended up to use three/4-inch plywood or MDF as the basis, I would then have to use a customized body with sufficient depth to protect the total thickness of the mosaic (i.e., 3/four-inch wooden basis additionally one/eight-inch tesserae equals practically a one-inch thickness). Custom frames expense up to 5 instances far more than standard pre-manufactured frames. For instance, by having edge of their biweekly fifty% sale at my preferred passion shop, I can get a pre-manufactured 18″x24″ frame in a pretty type and colour that ideal fits the mosaic, have the mosaic set up in the frame, have the hanging wire installed, and have paper backing installed, all for less than $25. That’s appropriate! Significantly less than twenty five bucks. A custom made-manufactured body may expense as much as $one hundred fifty.
Not only do I preserve on framing charges, the hardboard is cheap compared to 3/4-inch plywood and MDF. I acquire a pre-reduce area of hardboard instead of a entire 4’x’8 sheet. The pre-reduce part is 24″x48″. Knowing the height of my indoor wall mosaics is usually 24″ (which is the width of the pre-cut part), this enables me to cut the hardboard offering me a sixteen”, 18″, or 24″ width for my mosaic foundation. For instance, suppose I want my mosaic to be eighteen”x24″. topmozaiek24.nl/ -lower width of the hardboard I purchase is 24″. I measure and lower 18″, which results in a piece of hardboard which is 18″x24″. The piece matches completely in a normal eighteen”x24″ pre-made frame. I measure and reduce the hardboard utilizing a common circular observed and a “rip fence” that I make by clamping a 3-foot stage to the hardboard with two C-clamps. The rip fence makes it possible for me to push the saw together the straight edge of the degree to make certain a straight and exact cut.
I prepare the hardboard basis by portray it with two coats of white primer. The major purpose for portray it white is to get a white history on to which the glass tesserae will be adhered (Note: I usually adhere the glass to the rough aspect of the hardboard). Though I generally use opaque glass, the white qualifications helps brighten it up. The dim-brown coloration of the hardboard tends to make the glass pieces appear uninteresting and dark, even though the glass is meant to be opaque. The secondary advantage of portray the hardboard with primer is that it seals it. I don’t know if sealing hardboard does everything, but it helps make me really feel much better believing it is sealed. I will not know the substance or chemical properties of hardboard and how it truly is manufactured, so I never know if it demands to be sealed, but painting it presents me a wonderful, heat-and-fuzzy experience. I have a habit of sealing almost everything whether it demands it or not.
Soon after making use of the tesserae and grout, you will be surprised at how flexible the mosaic is with out causing glass or grout failure (assuming your tesserae are fairly tiny). When I 1st utilized 1/eight-inch hardboard as the foundation for a mosaic, I experimented and located that I could bend the mosaic a total two inches without having affecting the glass and grout. I was also concerned to bend it much more than two inches! Right after the experiment, I assumed if the mosaic can bend a whopping two inches, then it can survive any warping that might take place. Then, after the mosaic was mounted in the pre-manufactured frame, I understood that the mosaic was put in in such a manner to inhibit any warping at all. The mosaic was pressed and held in-area with the little fasteners in the again of the frame to maintain it from falling out. The only way the mosaic can warp is if it’s powerful adequate to cause the frame to warp with it. I’ve in no way experienced a dilemma with any indoor wall mosaic warping when making use of one/eight-inch hardboard mounted in a standard pre-produced frame.
one/8-inch hardboard is also lightweight sufficient so the weight of the general mosaic just isn’t so hefty that you have to rework your property to develop a support structure stout enough to maintain the fat of a mosaic. Typically, my 24″x24″ (or much less) mosaics are light adequate to adequately hold by indicates of a photo hook and nail installed in drywall. I will not have to lower into the drywall to put in two”x4″ pieces between the studs and then change the drywall. This is incredibly beneficial, especially when promoting or giving away the mosaic (i.e., you won’t drop clients that you may well in any other case drop if you inform them they have to hang the mosaic by undertaking some thing a lot more than pounding a nail into wall).
