Myths and facts about surface protection
Common assumptions, practical explanations and links to the full guides. These principles do not replace the instructions for a specific product.
Water beading proves lasting protection.
What to know: Beading is a sign of reduced wetting. It does not measure service life, penetration depth or resistance to other exposures. Ask for relevant tests on the intended substrate.
Read the explanation ↗All nano products perform better.
What to know: The word nano does not rank products. Formulation, material, preparation and test data matter when selecting a suitable system.
Read the explanation ↗An elastomeric coating fixes every leak.
What to know: Film flexibility does not replace diagnosis. Defective seams, fasteners or flashing may need separate repairs before coating.
Read the explanation ↗Corrosion-control paint can cover any rust.
What to know: Specified preparation remains necessary. Loose rust must be addressed according to the system, and perforated metal needs assessment; paint does not restore its thickness.
Read the explanation ↗A clear water repellent also prevents every stain and UV damage.
What to know: Water repellency, oil resistance and UV protection are distinct properties. Check product uses and evidence, particularly for exterior wood.
Read the explanation ↗Every advertised shingle treatment is accepted by the shingle manufacturer.
What to know: A seller’s claim is not shingle manufacturer approval. Check compatibility, warranty implications and acceptance of the specific product before proceeding.
Read the explanation ↗Two coats always guarantee the right result.
What to know: Coverage, specified thickness, preparation and application conditions must also be met. Coat count alone does not describe the full system.
Read the explanation ↗The cheapest quote is necessarily the best value.
What to know: Compare the same surfaces, repairs, preparation and warranties. A lower price may include less work; request itemized scopes before deciding.
