Summary

This DIY tutorial guides viewers through the process of creating a unique resin ashtray using wood powder. The step-by-step instructions cover preparing the mold with butter, mixing resin and wood powder with optional ink for color, and adding a catalyst for hardening. The video demonstrates pouring the mixture, creating a hole in the center using a bottle, and letting the resin harden. After sanding with multiple grits of sandpaper, the final touch involves applying polish for a glossy finish. This craft project combines creativity and practical steps to make a functional, stylish ashtray.

Takeaways

• 😀 Apply butter to the mold to prevent the resin from sticking.
• 😀 Mix wood powder with resin thoroughly for a consistent mixture.
• 😀 Add pen ink for color to the resin mixture, such as blue ink for a vibrant shade.
• 😀 Use a catalyst to help the resin mixture harden faster.
• 😀 Pour the resin mixture into the prepared mold and tap gently to level the surface.
• 😀 Allow the first layer of resin to dry completely before proceeding.
• 😀 Create a hole in the center of the dried resin using a buttered bottle to shape it symmetrically.
• 😀 Add wood powder around the hole after creating the indentation for added texture.
• 😀 Pour the second layer of resin mixture into the mold after the hole is made.
• 😀 Sand the hardened resin using multiple grades of sandpaper (180, 280, 500, 1000, 1500) for a smooth finish.
• 😀 Optionally, apply a polish or car wax to achieve a glossy finish on the ashtray.

Q & A

What materials are needed to make the resin and wood powder ashtray?

You will need resin, wood powder, butter (for coating the mold), an Aqua bottle (for shaping the mold), catalyst (for hardening the resin), pen ink (optional, for coloring), sandpaper (various grits), and polish (optional for finishing).

Why is butter used in the molding process?

Butter is used to coat the inside of the mold to prevent the resin from sticking to it, ensuring the resin can be easily removed once it has set.

What is the purpose of adding a catalyst to the resin mixture?

The catalyst is added to accelerate the hardening process of the resin, ensuring it cures faster and allows for quicker progress in the project.

Can the color of the resin be customized?

Yes, you can add pen ink or other colorants to the resin mixture to customize the color of the ashtray. In this tutorial, blue ink was used to color the resin.

What should be done after pouring the resin into the mold?

After pouring the resin into the mold, you should gently tap the mold to level the surface and remove any air bubbles for a smooth finish.

Why is a second layer of resin applied to the ashtray?

A second layer is applied to create a two-layer effect and to ensure the ashtray has the desired depth and structure. This also allows for the creation of a hole in the center of the ashtray.

How do you create the hole in the center of the ashtray?

To create the hole, a butter-coated bottle is placed in the center of the first resin layer, pressing down to form a symmetrical, circular indentation.

What sanding steps are involved in finishing the ashtray?

The surface of the ashtray is first sanded using a coarse grit sandpaper (180), followed by progressively finer grits (280, 500, 1000, and 1500) until the surface is smooth and polished.

What is the purpose of polishing the ashtray after sanding?

Polishing is done to give the ashtray a glossy, shiny finish, enhancing its aesthetic appeal. You can use polish products, such as motor kits, to achieve a smooth, high-gloss surface.

How long does it take for the resin to fully cure?

The curing time of the resin depends on the type of resin used and the environmental conditions, such as temperature and humidity. It's essential to allow each layer to fully harden before proceeding with additional layers or sanding.
