Quick Change Carbide Scrapers for removing thick glues and mastics

carbide scraper for removing gluecarbide scraper tools on a plate

The new carbide scrapers from Superabrasive feature replaceable tungsten carbide blades that quickly and easily remove thick glues, rubbery mastics and elastomeric coatings that bush hammers can not remove effectively because they will gum up and smear. These tools won't damage the concrete underneath, and are ideal for glue removal on floors that will be polished! Part number (individual trapezoid style tool) #X-HOLDER-CBL-19   

• Each scraper tool features a replaceable tungsten carbide blade, mounted to a reusable QuickChange style tool holder; Each blade has 4 different sides (19mm long each) to use for extended tool life. When one side is used up, simply turn the blade and start using the next side.
• These carbide scrapers can be used with electric LAVINA grinders and most other grinders on the market via QuickChange adapter plates. They work best on lower rpms (500-700 rpms), and are not suitable for use with propane Lavina machines.
• The CBL-19 holders feature a unique impact-resistant spring system, that prevents damage of the tools.
• Typically, the next step would be 30 or 50 grit metals.

Quick Change PCD Tools for Coating Removal

Superabrasive's PCD (Polycrystalline Diamond) tools are designed for aggressive stock and coating removal and are offered with the same QuickChange attachment as the standard metal bond QC tools. Please note that the PCD tools are directional specific and you should check the direction of rotation of the grinder heads. All Lavina machines WITH THE EXCEPTION OF PROPANE MODELS require standard right-hand rotation tools. LAVINA propane grinders require PCD tools with LEFT-hand rotation - those can be easily distinguished by their blue color.

PCD tools without Sacrificial bars or Metal Bond Button are the most aggressive style and will leave a very coarse profile on the concrete underneath. These are suitable for removal of:

• Thick mastics and glues

• ¼” Thick Parking Deck Membranes

• 30 mils and up Epoxy Coatings

• Thick Elastomeric Membranes
• Any coating with silica sand broadcast mixed in

PCD tools WITH Sacrificial bars or Metal Bond Button are designed to remove coating over a surface equal to a troweled surface and will not damage the concrete. The sacrificial bars or the metal button act as a stabilizer and depth guide, and reduce the gauging of the floor caused by the aggressive pcd segments. These tools are suitable for removal of:

  • Medium to thin mastics or glues
  • Failing epoxy coatings (30 mils or less)

Before deciding which tools to use for coating removal, you should inspect the floor before strating and answer the following questions:

• What type of coating are you removing?
• How thick or thin is the coating?
• Will you be recoating with a thick or thin mil system?
• Are you going to be polishing the surface?

Any bolts or other objects sticking up from the floor must be cut and hammered down into the floor to prevent damage to the tools and machine.
