Product Features
- Efficient Coating Removal: Lavina PCD features two half-round segments designed for effective removal of various floor coatings, including thick mastics, glue, elastomeric membranes, and epoxy coatings 30 mils thick or more.
- Aggressive Performance: PCD tools are significantly more aggressive compared to metal bond concrete grinding diamonds, making them ideal for tackling very thick and stubborn coatings with greater ease.
- Directional Considerations: Unlike metal bond diamonds, PCD tools rely on the edge for coating removal, making directionality important for effective use.
Description
This Lavina PCD is equipped with two half-round PCD segments, designed for efficient removal of various floor coatings, including thick mastics, glue, elastomeric membranes, and epoxy coatings 30 mils thick or more. Compared to metal bond concrete grinding diamonds, PCD tools are significantly more aggressive and capable of tackling very thick and stubborn coatings with greater ease.
6 types of coating removal tools
There are six main types of diamond tooling used for floor coating removal, listed below from left to right in increasing order of aggressiveness. Metal bond segments are the least aggressive, while PCD tools are the most aggressive. Additionally, bush hammer tools can also be effective for removing floor coatings in certain situations, such as line marking removal.
Metal bond segments only
Certain segment shapes, like arrow and zigzag segments, are suitable for removing thin floor coatings. These shapes typically leave fewer scratches compared to PCD segments.
PCD mixed segments
These PCD mixed segment bars create a powerful tool for removing adhesives, sealants, and coatings from smooth or troweled surfaces without damaging the concrete.
Crushed PCD mixed segments
The crushed PCD fragments appear irregular. They are crushed or randomly broken into larger pieces, giving a more aggressive cutting or grinding action, especially on tough materials.
PCD + sacrificial segments
The sacrificial segments control the cutting depth of the PCD, reducing its aggressiveness and preventing damage to the concrete floor. This tool is well-suited for removing medium to thin mastics, glues, and failing epoxy coatings.
PCD + TCT(Tungsten Carbide Teeth)
Tungsten carbide teeth are commonly used in bush hammer tools. Although not as hard as PCD, tungsten carbide teeth can assist PCD in the removal of floor coatings.
PCD only
Among these six types, PCD is the most aggressive. It is used for removing thick floor coatings such as mastic, glue, and epoxy, and it leaves a coarse profile on the underlying concrete.
PCD directions
Generally, we don’t need to worry about the direction of metal bond concrete grinding diamonds, but for PCD floor coating removal diamonds, we need to care about it. Because different from the concrete grinding segments, the PCD doesn’t have a flat area for grinding, but it relies on the edge of the PCD for removing the coatings.
2 different directions of HTC PCD tools
Clockwise direction
Anticlockwise direction
When grinding, the PCD layer will work first and then the tungsten carbide layer will work as behind.
There are 2 reasons that why PCD floor coating removal diamonds have a direction.
The structure of PCD
PCD is the abbreviation of Polycrystalline Diamond. It has 2 layers, one is the tungsten carbide and the other is actually the PCD layer. Please check the photos below.
What we need to do is use the PCD layer to remove the coatings, correct? Therefore, the key is to align in a direction that allows us to use the PCD layer effectively. However, since we’ll be painting colors over the surface of the PCD tools and thus obscuring the PCD layers, we need an alternative method to identify the correct direction.
PCD welding
To securely weld the PCDs onto the steel base, we need to create grooves in the steel base to properly position the PCDs. During the welding process, the PCDs will be tilted in one direction to maintain a specific angle. Consequently, there is only one correct rotation direction that aligns with the orientation of the steel base.
We will print an arrow on the tools to indicate the right rotation direction.
Optional painting colors
Our standard colors for PCD floor coating removal diamonds are yellow and gold. However, similar to concrete grinding diamonds, we can also customize the color to your preference.
Packaging methods – Lavina PCD
The packaging methods for Lavina PCDs are identical to those used for Lavina grinding diamonds.
Our Lavina concrete grinding segments are thoroughly protected and packed before shipping to prevent damage during transit. We use three types of hard boxes, each lined with pearl cotton: green, brown, and white. The green box offers the highest level of protection, while the brown and white boxes are more environmentally friendly.
6 pcs per box
9 pcs per box
Different concrete grinding diamonds have various packaging methods based on quantity. For Lavina diamond tooling, we offer three different packaging quantities: 6 pieces per box, 9 pieces per box, and 12 pieces per box. Among these, the most popular option is 6 pieces per box.
To make the tools easily identifiable from outside the box, we affix a label on the surface of the box indicating the product name, diamond grits, and bond types.
