What is a sintered base?
Sintered bases are made up of masses of tiny particles compressed together, kind of like what you can do with wet sand. These particles are hard by nature and get harder in the compression/fusion process. This makes a sintered base very hard wearing and resistant to knocks etc. the down sides are that they are porous, so need regular waxing, especially hot wax which penetrates, expensive, and also quite hard to repair. When properly prepared they are very fast, but then so is an extruded base when also properly set up with wax. The wax stays on sintered for longer, because it penetrates, but when it is worn off, they ain’t quite so good!
