How should surfaces be prepared before applying encapsulants?

Preparing surfaces properly before applying encapsulants is crucial for ensuring the effectiveness and longevity of the encapsulation process. Proper surface preparation involves thorough cleaning and ensuring that surfaces are free from dust, dirt, grease, and any loose materials that could interfere with the adhesion of the encapsulant. This preparation allows the encapsulant to bond effectively with the underlying substrate, providing a protective layer that will contain lead paint and prevent exposure.

Simply cleaning lightly with a damp cloth or only dusting the surfaces may not adequately remove all contaminants, which could compromise the encapsulant's performance. Leaving surfaces untreated, on the other hand, completely disregards the necessary steps for effective encapsulation and poses a risk of lead exposure. Thus, the correct approach emphasizes the importance of ensuring surfaces are thoroughly and properly prepared to achieve the desired results in lead abatement.
