Before you can actually start painting at home, start with a critical look. Tips before painting at home.
Peeling paint, bare spots and blisters immediately catch the eye, but look especially for cracks, especially at the corners of windows, doors and frames. Wood rot can easily occur here. It is important to do the preliminary work before you start painting the house with enthusiasm
Peeling paint, bare spots and blisters immediately catch the eye, but look especially for cracks, especially at the corners of windows, doors and frames. Wood rot can easily occur here. It is important to do the preliminary work before you start painting the house with enthusiasm.
Also check whether the paint is dull or weathered, especially on the sunny side, where paint has a hard time. The tips and information below will help you make the right decisions when painting at home.
Do the adhesion test here and there: stick a piece of tape on the paint and pull it off with a jerk. If there is paint on the tape, the adhesion is poor. This is the rule used by the professional. If more than a quarter of the paint layer is in bad condition, remove the old layer, because repair is more work than applying a new one. If the adhesion is poor, you have no choice: the old layer has to be removed.
Scratch outside, bite inside
Removing paint outside the house is quickest with a hair dryer and scrapers. Let the hot air play over a surface of ± 30 x 30 cm until blisters appear in the paint. The layer is then soft enough to scratch away. The secret to effortless scratching is a sharp scraper. Sharpen a scraper regularly or use a scraper with interchangeable blades. Because paint fumes are released even when scraping without fire, it is better to use a paint remover indoors. Apply generously with a brush, let it work for some time and then put away the paint with a putty knife.
Note: After using the paint stripper, wash the woodwork thoroughly.
Tip: In the kitchen, for example, where grease deposits are unavoidable, it is best to use a more powerful degreaser than ammonia. For example Rinser
Always sand new and bare woodwork before applying the base coat. With this work you have a lot of convenience from a flat and a fist sander. You must not only sand, but also degrease a paint that is still in good condition. This is done in one go if you work with waterproof sandpaper and ammonia water.
Wood rot and cracks
Water can penetrate into the wood through a crack in the paint layer, causing wood rot under the paint. Scraping reveals those spots.
1) Carefully put away affected wood.
2) Repair the spot with a wood repair agent.
3) In vertical areas, hold the product in place with plastic wrap lined boards.
4) After hardening, you can plan, sand and paint the repair like wood.
With wood joints you almost always see cracks in the paint layer. They require a thorough and modern treatment
1) Cut out a crack U-shaped, make the groove at least 5 mm deep and wide.
2) Fill the groove with acrylic sealant. The kit remains elastic and can be painted over.
Environmental tip: scraped paint also contains substances that pollute the environment. Carefully brush off scraped paint and take it, along with other paint residues, to the municipal collection point for small chemical waste.
Filling or not filling?
It is better not to fill exterior paintwork, because filler is a weak spot in the paint system. Very noticeable damage can be removed with a 2-component filler. Also prefer not to use putty outside. Inside there is no objection to filler, but apply it as thinly as possible.
Restore paint layer
Thoroughly scrape off the bladders and bladders, using the painter’s hair dryer if necessary. Sand the bare spots well, sand the edges of damage smoothly. The spot is barely visible when repainting.
