Is it just the normal case of slapping the glue to the paper and hangin onto the wall or is there somethings I need to be aware of
Somethings you need to be aware of?....yeh..you could say....
Firstly....what are your walls like?
Make sure your walls are in good condition before you start..the ideal surface is lining paper, this will help maximise adhesion..stick it on well using a pre mixed adhesive
If your confedent and good with a knife, try and cut the lengths first on a paste table.....this will avoid you having to cut it when in position and running the risk of snapping the relief (which can be repaired with polyfilla)
Sponge the back of the paper with warm water and leave it to soak for half an hour...do a couple of bits at a time and leave them back to back...this will stop the water drying out to soon.
Remove surplus water from the backs after soaking and apply the glue.
Talking of which....make sure you give it a good stir.
Use a clean short pile roller to flatten the paper out not a papering brush....you will find this easier and it will help remove all trapped air.
In corners, cut the paper tight into internal corners...dont attempt to take it round of leave half an inch or so on the return wall.
As Jason said, read the intructions, thats vital with Lincrusta, use a Stanley knife as opposed to the snap of blade variety, and have plenty of spare blades at hand.
Leave for at least 24 hours before you attempt to decorate
Give the surface a good wipe over with white spirit to neutralise any Linseed oil which may be on the surface before you paint it
Id go for an oil based system.....failing that water based is ok.....but use an acrylic primer first...dont try and hump one coat of paint on...its far better to give it two or three thinner ones
Above all......take your time....this stuff isnt two bob blown vinyl.. most decorators cant or wont hang it.
Hope that helps.
