There are many good adhesives on the market that will perform well with Dreamscape. Always choose a primer and paste that are intended for "heavy duty vinyl wallcoverings". Keep in mind that adhesive for a lightweight paper type wallpaper product will not be strong enough for Dreamscape commercial products.
Commercial wallcovering adhesives generally come in two common forms - CLEAR or CLAY. Dreamscape recommends using Clear for most applications as it is easier to apply and clean. Clay is sometimes more suitable for difficult installs or where stronger adhesive is desired.
NOTE *Adhesives and primers should never be "cut" or "diluted" by adding water. This is a common practice of installers who either want to increase their yield or reduce viscosity for pasting machines. Changing the water content can adversely affect adhesive performance.

PRIMERS
A good primer on the wall is an important part of wall preparation. The primer allows the wallcovering to bond well, but also prevents the paste from absorbing too much into a drywall surface which could make removal difficult.
Our recommended primer brands are:
We recommend using a brand such as Zinsser Universal Shieldz primer. 
We do NOT recommend a similar product called Zinsser Gardz as this product creates a very strong seal on the wall and effectively prevents any of the moisture from the wet adhesive from passing into the drywall - this forces all of the moisture to try to escape through the wallcovering which could create bubbling or very slow curing time.
Our recommended adhesive and primer for wallcovering that is perforated / micro-perf / porous:
*these products are for special use case where the wallcovering you are installing has been perforated or is permeable and requires an adhesive and primer system that will not eliminate the perforated holes.
