Scrapers described by manufacturers as ‘heavy-duty’ are designed for heavy work, usually on an industrial scale. They are made to withstand prolonged use and are resistant to conditions such as weathering.
A heavy-duty scraper is much more durable and will last longer than a standard scraper. As a result, heavy-duty scrapers are better at tackling more stubborn materials than standard scrapers.
If you are likely to be using a scraper over a long period of time rather than on a couple of occasions, it is advised that you invest in a heavy-duty scraper instead of a standard scraper or stripper.
