Spackling paste


In the United States, spackling paste is a putty used to fill holes, small cracks, and other minor surface defects in wood, drywall, and plaster. Typically, spackling is composed of gypsum plaster from hydrated calcium sulfate and glue.

Trademark

Spackle is a registered trademark of the Muralo Company, located in Bayonne, New Jersey. Muralo's product is dry powder, to be mixed with water by the user to form putty or paste. It was brought to market in 1927, then patented and trademarked in 1928. The term "spackle" has since become a genericized trademark applied in the United States to a variety of household hole-filling products.
The first written appearance of the generic use of the word "spackle" was around 1940. The product name was likely derived from the German word spachtel, meaning "putty knife" or "filler." Other possible origins include Russian шпаклевать, Polish szpachla, and Yiddish spaklieven, all of which are likely derived from German.

Polyfilla

In the UK, Ireland, South Africa, Australia, and Canada, the brand "Polyfilla", multi-purpose filler, is used as a generic term for spackling paste, even though it differs from spackle in being cellulose based. The manufacturers claim that it has an advantage over spackle in that it doesn't shrink or crack.
