"Hello,

You can apply knot stabiliser to help prevent knots working loose over time, but they will typically still be visible through stain, as the purpose of stain rather than paint is to maintain the appearance of the wood grain.

Hope that helps,


Phill"

"Ensure each layer (knotting solution, primer, stain, and topcoat) is fully dry before proceeding to the next step.
Work in a well-ventilated area and follow all safety guidelines on the product labels.
Test the stain on a small, inconspicuous area first to ensure the desired color is achieved.
By following these steps and using the recommended materials, you can effectively obliterate the knots in pine wood, apply stain, and achieve a durable, beautiful finish."

"If your staining you can't really hide them but to stop any remaining sap etc Ronseal knot stop is great also I find "Sikkens" woodstains the best and long lasting.
Hope this helps"

"Hi Andrew.
If these knots are in the places where the door is fixed, it is not possible to remove them because the wood will become weak. However, if they are in places where nothing is fixed, they can be removed and any wood putty can be applied, then the paint can be applied. The best paint is lacquer, which gives the wood its color and has light or dark shades.
Regards"

"When staining pine wood, especially when it has knots, it’s important to take specific steps to ensure a smooth finish and to prevent the knots from bleeding through your stain. Here’s a guide on how to effectively prepare your pine door frames, architraves, and skirting boards before staining, as well as recommendations for materials.

### 2. Treating the Knots

**Knots Sealing:**
- To effectively seal the knots and prevent them from bleeding through your stain, apply a clear shellac or a knot sealer.
- **Recommended Products:**
- **Zinsser BIN Shellac-Based Primer**: This is a popular choice that can quickly seal knots and prevent bleed-through. It dries quickly and can be painted or stained over once dry.
- **Knotty Pine Knot Sealer** (by various manufacturers): You can find specific knot sealer products in your local hardware store.

### 3. Staining Your Pine

**Choosing the Stain:**
- Select an oil-based or water-based stain depending on your preference. Oil-based stains tend to provide richer colors and deeper penetration, while water-based stains are easier to clean up and have less odor.
- **Recommended Stains:**
- **Minwax Wood Stain (Oil-Based)**: Known for its range of colors and ease of use.
- **Varathane Water-Based Stain**: Good for a variety of surfaces and has a lower odor.

**Application:**
- Apply the stain with a clean cloth, brush, or foam applicator, working in the direction of the grain.
- Allow the stain to set for a few minutes, then wipe off the excess.

### 4. Finishing Touches

**Topcoat:**
- To protect the stained surface, apply a clear protective topcoat. This can be a polyurethane (either oil-based or water-based).
- **Recommended Topcoats:**
- **Minwax Fast-Drying Polyurethane (Oil-Based)**: Durable and works well over stained wood.
- **Varathane Water-Based Polyurethane**: Quick-drying, easy to clean, and low odor.

### 5. Potential for Knots Bleeding

Knots can sometimes bleed through even after sealing. To minimize this risk:
- Ensure the knots are properly sealed with a good quality knot sealer or shellac.
- If a knot still bleeds through after staining, you may need to lightly sand the area and apply more stain or another coat of sealer.

By following these steps and using the recommended materials, you should achieve a smooth, beautiful finish on your pine frames that complements your oak doors well. If you have any further questions or need additional assistance, feel free to ask!"
