Why
Waterborne? PRODUCTS |
LACQUER VS. WATERBORNE: WHICH IS MORE COST EFFECTIVE?Some finishers are put off by the apparently high cost of waterbornes. Why pay over $35/gallon for a waterborne when lacquer is $20 to $25? PORE FILLING: BIGGEST TIME WASTERFilling porous grained wood with solvent based filler is a time consuming, expensive process. If you make a mistake and leave filler on top of the wood, you may not know it until the blotch appears, then it's too late. Dealing with toxic and flammable solvent is no fun, either. The PianoLac system turns a bottleneck into a breeze! Filling is now part of the sanding process. The filler goes on with a squeegee in minutes, dries in a half hour, and sands off like wood! It's ready to stain and seal immediately! There's no chance of making a mistake, since it's all sanded off. All in all, PianoLac Pore Filler Cream saves 20% of the labor involved in piano finishing. This doesn't include the savings in re-work time. Here's where most waterbornes beat out lacquer. Typical waterbornes have 35% to 40% solids content; that is, the resin coating that's left on the wood after it dries. Some lacquers have upwards of 30%, but most are 22% to 25%. Add thinner, and the solids content drops to less than 20%. APPLIED COSTThis means you have to use twice as much lacquer for the same thickness. THE APPLIED COST OF THE LACQUER IS ALMOST $50.00/GALLON1 HIDDEN COSTSThe standard spraying technique for lacquer is four passes/coat. With PianoLac, one pass is all that's needed, saving time and labor. Sanding between coats is unnecessary with PianoLac. This means a significant savings in labor and sandpaper. CURING: What is the cure to rub time of a high build, compliant lacquer? Two to six weeks is not uncommon. A thick coat of PianoLac can be polished to a high gloss after three day's cure, sooner if subjected to warm, circulating air. APPEARANCE: PianoLac is 100% clear. You may have heard this claim before and been disappointed by the blue or grey cast of other waterbornes. Apply multiple coats of PianoLac over a red mahogany stain, leaving a section uncoated. You will see no difference in color. The red remains red; it doesn't turn purple. This is a real advantage when preparing color samples for clients. With PianoLac, you know that the finished product will be the same color as the sample, no matter how many coats are applied. Prove it: spray mulitiple coats of clear over black, leaving part of the black uncoated. The clearcoat will not look grey or hazy. HASSLE FREEHigh build lacquers can have multiple problems that don't happen with PianoLac. BLUSHING: It's almost impossible to make PianoLac blush. An experiment was done by spraying a too thick, wet coat on a 100% humidity day, with no air circulation. This created blush. Then a thinner coat was sprayed, with good air circulation at 100% humidity. There was no blushing. What about lacquer in high humidity? You must resort to a slower thinner, or add retarder. Both make the coating soft .This delays the final cure.. Building up multiple coats of such a finish makes the surface vulnerable to printing. It can burn under the friction of machine polishing. Time is money. While you're waiting for lacquer to cure, PianoLac is ready and out the door. CLEANUP: PianoLac cleans up with water. Maintain the gun by shooting water through it when you'ree finished spraying. Take it apart at the end of the day and soak it in water. SANDING AND RUBBING: PianoLac Sanding /Barrier Coat sands very easily and doesn't roll up. The topcoat sprays out so smoothly, you can start wet sanding with #600 paper-no need to begin at #220 and march up the grits to cut down orange peel. |
