Pro tips
On Belgian renovation projects, it is advisable to test the dilution on a small, inconspicuous area before treating the entire surface, especially on older walls where multiple layers of wallpaper may overlap. To save time on large surfaces, work in two teams: while the first team applies the stripper to one area, the second team removes the wallpaper from the previously treated area that has already been well soaked. With a 1-litre container, you have enough product to treat between 300 and 600 m² depending on the type of covering, which allows you to plan your supplies accurately on medium-sized projects.
FAQ
Can I use Sem-Stripper on all types of wallpaper?
Yes, this stripper is compatible with standard wallpaper, heavyweight wallpaper, specialty wallpaper, and vinyl and expanded vinyl coverings. Simply adjust the dilution according to the type of covering: 100 ml per 10 litres of water for standard wallpaper, 200 ml per 10 litres for heavyweight or specialty wallpaper.
How long should the product be left to work?
The recommended working time is 10 to 15 minutes after application. This time allows the product to penetrate sufficiently to soften the adhesive and facilitate removal. For particularly stubborn coverings, you can repeat the application if necessary.
How do I treat vinyl wallpaper that is waterproof?
For vinyl wallpaper, it is essential to score the covering using a metal brush or perforation tool before applying the stripper. This step allows the product to penetrate the waterproof vinyl layer and reach the adhesive underneath.
What surface area can I treat with a 1-litre container?
With a 1-litre container of Sem-Stripper, you can treat approximately 300 m² of standard wallpaper, or approximately 150 m² of heavyweight or specialty wallpaper, depending on the dilution used. A yield of 100 ml per 30 m² allows you to plan your requirements accurately.
Is the product environmentally friendly?
Yes, Semin Sem-Stripper is formulated with a composition that is over 90% biodegradable, making it a suitable choice for projects concerned about environmental impact whilst maintaining professional efficacy.
