I have pre pasted wallcovering. Does it still require additional paste or activator?
It is common practice with many good paperhangers to use a paste designed for pre pasted wallcovering. Using a water trough (sometimes referred to as the lick and stick method) is easier and quicker, and manufacturers, in their instructions, do show this method for installing pre pasted wallcovering. However, I have found that the dry cellulose paste used with most pre pasted wallcovering does not adhere well over time. I have found this to be especially true with pre pasted border that is being hung over wallcovering or glossy paint. There is paste specifically designed for pre pasted border.
