Renovation: Old painters rule: „ A paint is only as good as the qua lity of the substra te“ . reason f or reclaims in exterior paints ! 

Adhesion loss very often

Pretreatment of great importance: Check the substrate (old paintings) , Surface mechanically cleaned and disinfested, fix the substrate with deep penetrating primer, repair cracks, and finally ...

apply the paint in 3 coats –at least in 2 (the first one diluted), being the total layer at least ca. 300 g/m 2. L.Santos: E-EDK/BA

Interi or pain ts: DIN 13300 

The main differences of this norm with the old one is that now is important to verify which is the hiding power we can get for the same abrasion resistance.



The old scrub resistance level (now ~ class 2: 5 to 20 µm in abrasion) which could be reached then with >5000 scrubs, is now in the class 2 dominated by PVAc binders because for the lower PVC level (when compared with class 3) at which we have to work –and where is no possible to make use of the dry hiding effect – it is easier to reach higher Hiding power, or same Hiding power with lower amount TiO2, than if we use SA binders instead.



The old wash resistance level (now ~ class 3) which could be reached then with >2000 scrubs, is now in the class 3 dominated by SA binders because for higher PVC level at which SA binders have higher pigment power than other binders, at which we can work with the dry hiding effect (introduction of included air pores – refractive index of air ca. 1,00 - and for that not using so much TiO2, it is easier to reach higher Hiding power for the respective abrasion resistance level (20 to 70 µm)



The class 1 is a very special class of paints (< 5 µm of abrasion) with very low PVC, very much high level of binder with higher gloss level and in principle is possible to reach with all kind of binders. However for the same abrasion resistance the hiding power is eventually higher with PVAc (refractive index ca. 1,45-1,47) Pure acrylics (refr. Index ca. 1,45) than with SA binders (refr. Index ca. 1,55 – 1,59), or using eventually TiO2, due to the refractive index differences between TiO2 and the used binders in each case.



The hiding power in class 2 (and eventually class 1) is easily to reach with binders which presents higher refractive index differences with TiO2 ( refractive index 2,70-2,76) -which is the case for PVAc or pure acrylics than with SA binders. The higher the differences the higher the hiding power.

The paint is applied on 2 coats on Gypsum or other type of substrate (without plaster, tissue and primer)

2.

After 1 week the painted gypsum is cut in small square forms with 10cmx10cm

3.

After that the painted sample is left for ca. 3 days to dry out, being after that sealed with a 2K-epoxy system in all their back-uncovered sides

4.

The painted sample is weighted. After that, in a box these painted surfaces turned downside, are put in contact to an high absorbency surface sponge which should be from their part immerse in water until at least the half their thickness

5.

To avoid evaporation a PE film should be used to cover all the test samples

After 4 weeks the sample in test, after being cleaned with a paper should be weighed again. The water absorption should be then calculated in relation to the exposed area and should be max. between 350 and 400 g/m2 or less . Important to control the real thickness applied. All the areas not to be exposed should be perfect sealed, as well as to be sure about the exact measure of area to be exposed to the test. Small slips by each of these conditions could bring to important differences in the final values in water uptake.
