Differences between the two are as follows. Basilemma is a kind of professional material of high alkali resistance, humidity resistance and mildew resistance for surface treatment of wall. It can effectively prevent the humidity and alkaline substances of cardinal plane of construction from exosmosis which can keep the wall from the damage of getting damp, mildew and nigrescence and so on. The so-called "primer" is a kind of coating which can be directly painted on the surface of the substance as solid foundation of finishing coat. It is required to firmly attach itself to the surface of substance to increase the adhesion of upper layer and the decorative effect of finishing coat.
Compared with the common primer, basilemma has the feature of perfect transparency and no hiding power. You don't have to worry about the workability and finishing effect. In brief, good latex?paint primer is equivalent with basilemma (wallpaper primer). But it is of high price. So it is not recommended. But if the price of your basilemma is much higher than latex?paint primer, it's better to choose the transparent sealing latex?paint primer with better quality as the wallpaper sealing primer. But in contrary, perfectly transparent wallpaper primer (wallpaper basilemma) can't take the place of the latex paint primer.
The main difference is as follows.Primer is used as back cover. Basilemma can be used as back cover as well as interface agent which can increase the adhesion of sublayer and surface layers.Besides, primer often contains formaldehyde, some of them can even release the formaldehyde (materials containing formaldehyde used on outer wall are not forbidden by national standard). However, quality products of primer are environmental friendly and odorless. So it's better to choose primer as wallpaper.
