Test to Find a Durable Finish

To determine the relative scratch resistance of a finish, push the sharp edge of the cylindrical lead in various “B” and “H” architect’s pencils forward on a finish. There’s no need to use pressure. The next-to-hardest pencil that doesn’t scratch the finish is the rating for that finish. !function(f,b,e,v,n,t,s){if(f.fbq)return;n=f.fbq=function(){n.callMethod? n.callMethod.apply(n,arguments):n.queue.push(arguments)};if(!f._fbq)f._fbq=n; n.push=n;n.loaded=!0;n.version='2.0';n.agent="dvpixelcaffeinewordpress";n.queue=[];t=b.createElement(e);t.async=!0; t.src=v;s=b.getElementsByTagName(e)[0];s.parentNode.insertBefore(t,s)}(window, document,'script','https://connect.facebook.net/en_US/fbevents.js'); var aepc_pixel = {"pixel_id":"376816859356052","user":[],"enable_advanced_events":"yes","fire_delay":"0"}, aepc_pixel_args = [], aepc_extend_args = function( args ) { if ( typeof args === 'undefined' ) { args = {}; } for(var key in aepc_pixel_args) args[key] = aepc_pixel_args[key]; return args; }; // Extend args if ( 'yes' === aepc_pixel.enable_advanced_events ) { aepc_pixel_args.userAgent = navigator.userAgent; aepc_pixel_args.language = navigator.language; if ( document.referrer.indexOf( document.domain ) < 0 ) { aepc_pixel_args.referrer = document.referrer; } } fbq('init', aepc_pixel.pixel_id, aepc_pixel.user); setTimeout( function() { fbq('track', "PageView", aepc_pixel_args); }, aepc_pixel.fire_delay * 1000 );
