After spending hours of effort onto that awesome pencil artwork, the last thing you would do is just close the sketchbook up, only to find out it was all smudged up next time you open it.
The fixative spray is specially designed for protecting graphite, charcoal, pencil, pastel, and chalk from dusting, smudging and fading. They can also provide UV protection without dissolving whites and lights.
Many big art brands provide their fixative spray and I got the Krylon Fine Art Fixatif for S$19 from local art supplies store. There is 2 kind of fixative spray, the workable fixative, and the final fixative. Workable fixative saves the progress of work and further touch up can still be added on to the medium. When everything is done, the artwork may seal up with the final fixative.
Krylon Fine Art Fixatif is somewhat in between, as it provides workable and final protection. Apply a thin layer for the workable layer and a few layers consecutively for the final varnishing result.
最不想看见的事辛苦创作的铅笔画在画完之后，因为没有妥善保存，下次再看时已经模糊不清了。保护喷胶就可以完美解决这问题，还可以防紫外线。我在本地的画具店卖了Krylon Fine Art Fixatif，价格是新币19元。这支有点特别，喷一层薄的就可以锁住目前的进度，还可以继续在上面加工。如果完工了要完全封锁效果，就连续喷上数层即可。
I will varnish my Eagle which was a contest entry weeks ago using the fixative spray. Mark any area that you don't want to spray, in my case I want to spray the whole figure.
我会用用数个礼拜前的参赛作品《老鹰》来示范。先将不要被喷到的地方掩盖起来，我则要覆盖整个图像。
Shake the spray every time before using it.
使用之前先摇匀。

Test spray in an inconspicuous area for compatibility.
在通风的地方试喷几下以确保正常运作。

Spray artwork in the upright position. Begin at closest edge and stroke from left to right across the surface and beyond the edge. Overlapping slightly for every stroke. Since the work is already done and no more tuning is needed, I will apply a few layer to achieve the final fixative result.
将作品垂直摆放。由左至右一道一道的喷，每道之间稍微互相覆盖以确保每寸图像都有被照顾到。因为这已经是完成的作品，我将直接喷上数层将之完全封锁起来。

The coat will dry in 15 minutes. I tried to erase the pencil drawing but the graphite stays on. We can know now everything is locked up within the coat!
保护层只需要15分钟就会干透。这时用橡胶试一下擦拭，并不能擦去任何痕迹了。完美！
