To use Durham's Rock Hard Water Putty, you primarily fill voids like holes and cracks, ensuring the area is completely packed until the putty pushes back.
Durham's Rock Hard Water Putty is specifically designed to fill imperfections in surfaces. Its water-activated formula hardens to a durable finish that permanently adheres to the sides of the void it fills.
Here's a breakdown of the process based on its intended use:
Step-by-Step Application
Using Rock Hard Water Putty is a straightforward process involving preparation, filling, and finishing.
Preparation
Before mixing and applying the putty, ensure the area to be filled is clean and free of loose debris. This helps ensure strong adhesion.
Mixing
Rock Hard Water Putty comes in a powder form. You typically mix it with water to achieve a workable consistency. Follow the manufacturer's specific instructions for the correct water-to-powder ratio, as this can affect setting time and hardness.
Filling the Void
This is where the key application method comes in. According to the reference, you:
- Fill the void completely until the putty bounces back. This means pushing the putty firmly into the hole or crack, ensuring no air pockets remain and the material is tightly packed. The slight resistance or "bounce back" indicates the void is fully packed.
Setting and Curing
Once the void is filled, allow the putty to set up. The time required can vary depending on the mixture consistency, humidity, and temperature.
Removing Excess
After the putty has set and is firm:
- Remove the excess. You can typically scrape or sand away any putty that is above the surface level of the surrounding material to create a smooth, flush finish.
Finishing
Once fully cured (which may take longer than just setting), the filled area can usually be sanded, drilled, painted, or stained, just like the material it's filling.
Where to Use It
Rock Hard Water Putty is ideal for:
- Filling nail holes and screw holes
- Repairing cracks in wood, plaster, and other porous surfaces
- Patching damaged areas before painting or finishing
Its ability to adhere permanently to the sides of the hole makes it a reliable choice for long-lasting repairs.
Using Rock Hard Water Putty is effective for repairing various voids by properly filling the space until full, allowing it to set, and then finishing the surface.
