In the paint and coating industries, paint adhesion testing is often used to determine if the paint or coating will adhere properly to the substrates to which they are applied. Several tests measure the resistance of paints and coatings from substrates: cross-cut test, scrape adhesion, pull-off test , and others.
A test patch should be as clean as possible. Contamination of a patch can influence the results significantly. Bresle patch injected with 15ml water as in ISO 8502-6 Annex A. The ISO 8502-6 standard prescribes in annex A that certified patches shall be used. This annex describes a stress test to ensure patch adhesion and wash ability.
Highly oxidized red soil in Tirunelveli District, India. Red colors often indicate iron accumulation or oxidation in oxygen-rich, well-aerated soils. [4] Iron concentrations caused by redox reactions because of diffusion of iron in crystalline and metermorphic rock, in periodically saturated soils may also present red colors, particularly along root channels or pores.

3. Swap Bright Colors for Muted Tones. Instead of bright pops of color, get ready for accent colors to come in gentler hues. "Pops of color will take on muted or dusty shades," Eisenhart predicts.
Paint and other coatings that are on slanted or vertical surfaces tend to sag when first applied. The thickness of the coating as well as the composition and viscosity will affect the overall sagging and conversely the sag resistance. In order to find the sag resistance of a coating a simple test is used.
