If you leave any type of paint in an open container it will dry up,so always return unused paint back to tin and replace lid.

Bubbles will normally for for different other reasons, but certainly not that one.

Hi Ben,
As long as you put the tray in a plastic bag and seal it that should be ok? Same with brushes and rollers put in plastic bags and seal

Paint bubbles in emulsion paint can be a frustrating issue, and they are usually caused by a few common factors. Here are some potential causes and solutions:

Causes of Paint Bubbles:
Moisture: One of the most common causes is moisture trapped underneath the paint. This can happen if the surface wasn't completely dry before painting or if there's moisture within the wall.

Surface Contamination: Dirt, dust, or grease on the surface can prevent proper adhesion of the paint, leading to bubbles.

Improper Preparation: Skipping steps like priming or not sanding a glossy surface can cause poor adhesion, resulting in bubbling.

Application Errors: Applying paint too quickly, too thickly, or using the wrong type of roller can introduce bubbles.

High Humidity: Painting in high humidity conditions can cause the paint to dry too slowly, leading to bubbles.

Previous Coats: If the previous coat of paint wasn’t allowed to dry completely before the next coat was applied, it can cause bubbling.

Solutions:
Allow Drying Time: Ensure the surface is completely dry before painting. If painting in a high humidity environment, consider using a dehumidifier.

Clean the Surface: Thoroughly clean the surface with soap and water to remove dust, dirt, and grease. Let it dry completely before painting.

Proper Preparation: Sand any glossy surfaces to create a texture for the paint to adhere to. Use a primer if necessary, especially on difficult surfaces.

Correct Application: Apply the paint in thin, even coats. Use a high-quality roller or brush designed for emulsion paint. Avoid overworking the paint, which can introduce bubbles.

Wait Between Coats: Allow adequate drying time between coats. Follow the manufacturer’s recommendations for drying times.

Fixing Existing Bubbles:
Let the Paint Cure: Sometimes bubbles will disappear as the paint cures. Give it some time to see if this happens.

Pop the Bubbles: If bubbles persist, you can gently pop them with a pin or a knife.

Sand and Repaint: Once the paint is completely dry, sand the bubbled areas smooth, clean the dust, and repaint the affected area.

Address Moisture Issues: If moisture is the underlying cause, address any leaks or sources of dampness before repainting.

Hi Ben.  Silk is a terrible paint to work with and is really best suited to very high traffic areas such as schools.  Switch to eggshell if you really want a shine. It's just as durable and washable.  Better finish too.  
Best thing to do with Silk is to just put it back in the tin after use and seal it. Takes a few seconds and you won't need to worry about bubbles. Put the brush and rollers onto a freezer bag and seal or cling film and you will be ready to go in the next day.
