What should I do if the wall is discolored? How to remedy the fading of wallpaper?

You must have had the experience of buying faded clothes, and that feeling is like finally buying a satisfactory piece of clothing that was caught in the rain, and then left behind black rain, isn't it terrifying. But in any case, it is indeed very embarrassing to fade clothes, and in the same way, the fading of the wall is also unbearable, which is quite embarrassing!!

As you can see in the picture below, the original glamorous wall has lost its former charm.

So, is there any good solution? Don't worry, let's first understand what causes the fading of the wall.

1. The structure of the wall paint.

The main components of wall paint are emulsions, titanium dioxide, fillers and additives. Among them, the main ingredients that affect the fading of the wall are emulsion and titanium dioxide. The emulsion in most wall paints is acidic, and the value of the wall is alkaline or strongly alkaline, so when the wall paint is combined with the wall, over time, the alkalinity of the wall gradually oxidizes the acidity of the wall paint, thus forming our common wall powder, aging and fading.

2. Problems in construction.

The primer and topcoat are not combined;

Dust or oil stains;

The primer is too smooth for the topcoat to hang;

Too much hardener. Usually, the mixture of nitro paint and polyester paint underside is easy to occur.

3. The influence of the natural environment.

The organic pigment of the latex paint on the wall is greatly affected by the climate, and the stability is relatively poor, and the latex paint will change color when exposed to ultraviolet rays under the condition of sunlight for a long time;

If the painted wall is constantly exposed to moisture and water seepage, it will also cause the wall to fade.

To prevent paint and coatings from fading and affecting the aesthetics of your home, you can do this:

1. Use a suitable primer to seal the base layer of the wall.

For the best results, it's best to apply a primer first, whether you're renovating a new wall or renovating an old wall. New walls generally choose primers with anti-mildew and anti-corrosion properties; For older walls, choose a water-solvent primer. Otherwise, if the primer is not applied, but the paint is applied directly, it will cause the topcoat to bloom and yellow because of the alkalinity of the lime water, which will seriously affect the decorative effect.

2. It is recommended to choose a darker color, which usually has better weather resistance and alkali resistance;

3. Follow the construction specifications.

Be sure to strictly follow the construction specifications for construction, and ensure that the alkalinity of the wall substrate meets the construction requirements, especially the repaired part. Note the following:

The construction temperature should be above 5, and the film-forming additives should be selected appropriately and the amount should be increased appropriately to ensure that the wall paint forms a continuous coating film and the appropriate Yanyi base ratio is selected;

Remove the loose layer, and at the same time, do not increase the amount of makeup and filler too much to reduce costs.

Deal with the base layer, clean up the milk dust and oil, and choose putty with good bonding strength;

According to the different requirements of the interior and exterior walls, the putty layer should not be too thick (subject to the leveling wall), and the putty must be applied after drying to enhance the adhesion of the coating;

Substrates that are too smooth should be treated with an interface agent to reduce shedding.
