Yes, it is possible to paint an interior door with wall paint, but it may not be the best option. Wall paint is not as durable as paint specifically designed for doors, so it may not hold up as well to the wear and tear that doors typically experience. Additionally, wall paint may not provide the same level of coverage and finish as door paint, leading to a less professional-looking result. It is recommended to use paint specifically formulated for doors and trim for the best results. **

To paint a wall with wall paint, start by preparing the surface by cleaning it and filling in any holes or cracks with spackling compound. Next, apply a coat of primer to the wall to ensure better adhesion and coverage of the paint. Once the primer is dry, use a paint roller to apply the wall paint in even, overlapping strokes. Start from the top of the wall and work your way down, and be sure to use a paintbrush to cut in around the edges and corners. Allow the first coat to dry completely before applying a second coat if necessary for full coverage. **

Yes, it is possible to paint blue or turquoise over a red wall, but it may require multiple coats of paint to fully cover the red color. It is recommended to use a primer before applying the new color to ensure better coverage and adhesion. Additionally, choosing a paint with good coverage and opacity will help achieve the desired blue or turquoise color without the red showing through. **

To paint over a nicotine-yellowed wall with light blue, you will first need to thoroughly clean the wall to remove any nicotine residue and dirt. Once the wall is clean, apply a primer specifically designed to cover stains and discoloration, which will help to prevent the nicotine from bleeding through the new paint. After the primer has dried, you can then paint the wall with your chosen light blue color. It may be necessary to apply multiple coats of paint to achieve the desired coverage and color intensity. **

Without further information or inspection, it is difficult to determine if the interior wall paint is still good. Factors such as the age of the paint, any visible damage or wear, and the quality of the original application can all affect the condition of the paint. It is recommended to visually inspect the walls for any signs of peeling, cracking, or discoloration to assess the current state of the paint. **

To remove paint from an interior wall, you can start by using a paint scraper or putty knife to gently scrape off the old paint. If the paint is stubborn, you can try using a chemical paint stripper or solvent to help loosen the paint. Make sure to follow the instructions on the product carefully and use proper ventilation. After removing the paint, you may need to sand the wall to smooth out any remaining paint or rough patches. Finally, clean the wall thoroughly to remove any residue before applying new paint. **

To plaster a wall with interior paint, start by preparing the wall surface by filling in any holes or cracks with spackling compound and sanding the surface smooth. Then, apply a coat of primer to the wall to ensure the paint adheres properly. Once the primer is dry, use a roller to apply the interior paint in a smooth and even manner, working in small sections at a time. Allow the first coat to dry completely before applying a second coat for a more even and durable finish. **

The presence of strange blue spots on the wall despite using silicate paint could be due to a few reasons. It is possible that the paint was not applied correctly, leading to uneven coverage or improper adhesion to the surface. Another reason could be that there was a reaction between the silicate paint and another substance on the wall, causing discoloration. Additionally, if the wall was not properly prepared before painting, such as not cleaning or priming the surface, it could result in unexpected discoloration or imperfections. **
