It's a two-part epoxy paint that you mix together by pouring part A (the activator) into part B (the base). You can use it on porcelain, ceramic, and fiberglass. Then use your brush to cut in the edges and corners, just like you would if you were painting a wall. When that is done go after it with a roller.

Mix soil and water into a thick mud. Add some sand, then mix in the straw, grass or pine needles. Pour the mixture into your molds. Bake bricks in sunshine for five days or so. If cracks appear, cover the bricks so they're not in direct sunlight. Remove the bricks from the molds and let them dry a few more days.

Resin is a thick clear finish that you pour on rather than brushing on. It gives the finished project a glossy, three dimensional look that more closely mimics the look of a true solid countertop. When the light from the window hits the countertop, it shines through the layers of the finish rather than simply bouncing off.

The exchange process The exchange process of sodium resin represented by RNa is as follows: 2RNa + Ca2+ = R2Ca + 2Na+ 2RNa + Mg2+ = R2Mg + 2Na+ After the water passes through the sodium ion exchanger, the Ca+ and Mg+ are replaced with Na+. Regeneration When enough calcium and magnesium ions have been absorbed by the resin, it must be regenerated.

Sand point wells are similar to dug wells in depth, with a steel pipe driven around 20' deep and a 1-1/4" to 2" diameter. A screen on the end of the point filters the water from water-bearing sand, and it's drawn to the surface by a pump. Choose from kits with a hand pump or a jet pump. Installing a water tank is optional.

Bubbles. If air becomes trapped in between individual layers of coating, bubbles can appear . This is sometimes due to the coating not curing properly, but it could also happen if the refinisher does not strip the tubs' old finish prior to resurfacing. A bathtub will only need stripped if it has been previously resurfaced, even with a DIY kit.

It works using positively charged ions attached to atomized particles. These particles gravitate to grounded, negatively charged metal. Much like a balloon with static electricity, the charge "sticks" the tinted particles to the object and disperses it evenly. Beyond that, it's much like standard spray painting without the mess.

Also known as abrasive blasting, sandblasting is a surface finishing process that involves the use of a powered machine — typically an air compressor as well as a sandblasting machine — to spray abrasive particles under high pressure against a surface. It's called "sandblasting" because it blasts the surface with particles of sand.

This water can, for drying purposes, be considered as free water at the surface. A comparison of the drying rates of sand, a material with mostly free water, with meat containing more bound water shows the effect of the binding of water on drying rates. Drying rate curves for these are shown in Fig. 7.5.
