The Marshalltown Blue Steel Scarifier M723 is a hand tool used to prepare plaster undercoats prior to applying a finish coat. It features blue steel tines designed to scratch the plaster surface to create a mechanical key for subsequent layers.
The tool includes 3"x1/4" blue steel tines and a plastic handle. The 12"(305mm) wide design allows the user to score the undercoat across a broader surface area during preparation.
Suitable for scratching plaster undercoats to provide a key for bonding with subsequent plaster coats.
The Marshalltown Blue Steel Scarifier M723 is a plaster preparation tool designed to scratch plaster undercoats before the application of a finishing coat. Scoring the undercoat creates a surface profile that assists with bonding between plaster layers.
The tool incorporates blue steel tines arranged across a 12"(305mm) wide head. Each tine measures approximately 3" in length and 1/4" in width and is intended to cut shallow grooves into the plaster undercoat during the preparation stage.
The scarifier is fitted with a plastic handle which provides the grip for manual operation during plaster preparation.
Function and Application
The primary function of the scarifier is to create scratches or grooves in freshly applied plaster undercoats. This process produces a mechanical key that helps subsequent plaster layers bond to the prepared surface.
The blue steel tines are arranged along the width of the tool to enable consistent scoring across the surface of the plaster. The 12"(305mm) width allows a larger section of the undercoat to be scratched with each pass of the tool.
By producing a keyed surface on the base coat, the scarifier helps prepare the substrate prior to the application of finishing plaster coats.
Construction
The scarifier head uses blue steel tines designed for scratching plaster undercoats. Each tine measures approximately 3" in length and 1/4" in width.
The tool is fitted with a plastic handle, allowing manual control during plaster preparation tasks.
The overall working width of the tool is 12"(305mm), enabling it to cover a wider area during surface preparation.
Preparation and Use
The scarifier is used during the plastering process after the undercoat has been applied. The tool is drawn across the plaster surface to produce scratches in the material.
These scratches create a keyed surface that allows the next plaster coat to adhere to the prepared undercoat.
The width of the tool allows the user to work across larger areas of plaster while maintaining a consistent scoring pattern.
Typical Applications
The Marshalltown Blue Steel Scarifier M723 is used in plastering and drywall preparation where a surface key is required between plaster layers.
Typical uses include:
-
Scratching plaster undercoats prior to finishing coats
-
Preparing plaster surfaces to receive additional plaster layers
-
Producing a keyed surface on base coats before applying topcoats
