Yes, there can be glue residue left on the wall after stripping wallpaper, especially if the stripping process wasn’t thorough. This residue can affect the adhesion of the primer and ultimately impact the finish of the new texture and paint. To ensure a smooth and flawless finish, it is crucial to properly clean the wall surface after wallpaper removal.

Priming the wall before applying texture and paint is essential as it helps seal the surface, promotes better adhesion, and evens out the porosity of the wall. However, if there are glue residues present, the primer may not adhere properly in those areas, resulting in uneven absorption and potential imperfections in the final finish. If there is a lot of glue you should use either an oil based or shellac primer, they will stick the best.

In order to address this issue, it is recommended to first wash the wall thoroughly with a solution of warm water and detergent to remove any remaining glue residue. After cleaning, allow the wall to dry completely before applying a high-quality primer specifically designed to seal porous surfaces and promote adhesion. By ensuring a clean and properly primed surface, you can enhance the overall finish and hide any imperfections that may have resulted from leftover glue residue. Remember, proper preparation is key to achieving a professional-looking result when painting over wallpaper-stripped walls.

Primer and paint won’t hide much in the way of imperfections. If anything they will draw attention to these areas. An applied texture will hide a lot, depends on the texture and its thickness. Light textures, light orange peel or a sand texture, hide the least while knockdown and heavy brush textures hide a lot.
