What has happened if black spots have appeared on the ceilings and high points of the walls?

The causes of black spots on the ceiling or on the walls are :

a) Increased humidity
b) Very dirty surfaces, which are food for the growth of microorganisms (fungi), which create black spots.
c) Surfaces that are not visible to the sun and are not properly ventilated.

The Solution

In case the cause of the phenomenon is the accumulated moisture, the causes that caused it must first be repaired (eg roofs, gutters, etc.). Once the moisture problem has been resolved, the following repaint procedure is recommended:
STEP 1. Thoroughly clean the surface with a biocidal product with disinfectant action (eg bleach), rinse and allow to dry.
STEP 2. Prime the surface  in case the surface is very absorbent (intense chalking effect or there is disintegration)
STEP 3. Paint two coats with fungicidal paint!

What has happened if moisture and mold have appeared on the lower parts of the painted surface?

CAUSE:

a) Increased humidity
b) Very dirty surfaces, which are food for the growth of microorganisms (fungi) that create black spots.
c) Surfaces that are not visible to the sun and are not properly ventilated.

SOLUTION: 

In case the cause of the phenomenon is the accumulated moisture, the causes that cause it must first be repaired (eg roofs, damaged piping, etc.). After solving the humidity problem, the following interior painting procedure is recommended:
STEP 1. Thoroughly clean the surface with a biocidal product with disinfectant action (eg bleach), rinse and allow to dry.
STEP 2. Prime the surface in case the surface is very absorbent (intense chalking effect or there is disintegration)
STEP 3. Paint two coats with the fungicidal paint!

What if cracks of paint have appeared in places where wall plastering has been done?

CAUSE

a) Apply paint to the plastering points without prior priming.
b) Use of poor quality paint
c) Use of putty or paretina of poor quality.

SOLUTION

The following repainting procedure is recommended:
STEP 1: Remove loose spots locally with a spatula or hard brush.
STEP 2: Priming the surface.
STEP 3: Plastering the surface with acrylic putty .
STEP 4: Apply in two coats the ecological plastic paint.

What should I do if local cracks of paint appear on painted surfaces?

Cause

a) Use of poor quality paint with unsatisfactory adhesion and elasticity.
b) Application of the paint without the surface being primed.
c) Apply a very thin layer or excessively diluted paint.

Solution

The following repainting procedure is recommended:
STEP 1: Remove loose spots locally and / or all the paint with a spatula or hard brush.
STEP 2: Prime the surface.
STEP 3: Apply in two coats the ecological plastic paint.

What happens if with light rubbing the paint comes out in the hand?

CAUSE

Use of poor quality paint (lime, watercolor, glue or mixing such materials with plastic paint).

SOLUTION

The following repainting procedure is recommended:
STEP 1: Remove the previous color, where possible.
STEP 2: Descaling the surface.
STEP 3: Priming the surface.
STEP 4: Apply in two coats the ecological plastic paint.

What has happened if in different parts of the painted surface the paint has peeled off?

Cause:

Poor adhesion due to:

a) Application of paint on a glossy surface, due to the use of undiluted primer.
b) Use of poor quality paint.
c) Insufficient surface treatment (dust, oil, and mold residues).
d) Accumulated moisture inside the masonry, which comes out through its pores.
e) Priming with poor quality primer.

Solution

If the cause of poor adhesion is moisture, the causes should be identified and corrected. After solving the problem of moisture in the wall, the following repaint procedure is recommended:

STEP 1: Remove the peeled paint from the surface with a spatula, sandpaper or hard brush.
STEP 2: Priming the surface with the correct dilution (so that the surface does not shine at all).
STEP 3: Apply in two coats the ecological plastic paint.

What has happened if on a painted surface there are spots that have a different shade from the one that was originally applied to the wall?

CAUSE

a) Uneven spread of the paint due to poor application (one roll intersects with the previous one after a period of time, which allows the paint to not have dried sufficiently).
b) Surfaces that have not been primed properly.
c) Surfaces with different porosity in places.
d) Excessive dilution of the paint.
e) Tint that has been made in a machine and presents problems in the dispersion of the pigments, due to their excessive quantity (floating).

SOLUTION

Re-painting of the surface in two coats with the ecological plastic paint  with the proposed dilution. The application of the paint on the surface must be continuous and not interrupted for a long time.

What happens if after painting there are spots where the paint on the wall did not adequately cover the surface?

CAUSE

a) The paint did not cover the surface because it is a paint of poor quality.
b) Excessive dilution of paint.
c) Application of color in intense shade (red, yellow, orange) made from a transparent base with pigments (organic pigments), low coverage (in these cases requires extra hand or hands).
d) Use of brushes or rollers of poor quality.

SOLUTION

Re-painting with the ecological plastic paint , with proper dilution according to the instructions for use, in the appropriate number of coatings for each shade.

What happens if surfaces painted did not show the relief effect?

Cause

a) Use of inappropriate roll
b) Excessive dilution of the paint
c) Use of poor quality paint
d) Application conditions different from the proposed ones e.g. High temperatures when applying the paint

Solution

Re-paint the surface with the correct product embossed coating without dilution. Application of the product with a special good quality roller.

What if the painted surface swelled?

CAUSE:

Lack of traction, locally, due to:
a) Surface painting at a temperature higher than 35 degrees Celsius.
b) Accumulated moisture inside the masonry (eg from a leaking pipe), which comes out through its pores, causing swelling in the paint.
c) Incoming moisture in the wall from the outside environment (terrace, soil with a high percentage of moisture, lawn, etc.).
d) Fresh surface painting.
e) Creation of petals of various sizes due to not well “extinguished” lime or poor quality plaster.

SOLUTION: 

In case the cause of the problem is humidity, the reasons that caused it should be identified and corrected with the help of appropriate materials. The following repaint procedure is recommended:
STEP 1: Rubbing the surface.
STEP 2: Stucco with acrylic putty .
STEP 3: Priming the surface.
STEP 4: Apply in two coats the ecological plastic paint.
* Re-painting should be done when the remaining moisture on the surface is the minimum possible (from May to October).

What should I do if there are marks left by a roller or brush on the painted surface?

CAUSE:

a) Use of poor quality paint
b) During the painting preparation of a surface, some parts of it are repainted locally, while the surface has not dried sufficiently.
c) Multiple passes of the roller or brush at the same point on the surface.
d) Use of poor quality roller or brush.
e) Use of low coverage paint

SOLUTION:

The following repainting procedure is recommended:
STEP 1: Rubbing the surface.
STEP 2: Priming the surface.
STEP 3: Apply plastic paint in two coats
