Will Sharpie stay on silicone?
You could purchase silicone-based sealant at a home improvement store and mix dry powdered artist’s pigments from an art supply store into it to make a colored gel, then apply, but this is kind of a lot of DIY and, while much more likely to stick than paint or permanent markers, it still may not adhere completely.
How do you seal acrylic paint on a silicone phone case?

How do you make silicone paintable?
Apply a very thin layer of siliconized acrylic latex caulk over the silicone caulk to paint over it. This second caulk will adhere to the silicone and make its surface a bit rougher and even more paintable. Allow it to dry thoroughly before you proceed to the next step.
Will any paint stick to silicone caulk?
While 100% silicone caulk will stick fine to paint, paint won’t stick to 100% silicone caulk. If you plan to paint over the caulking, use a paintable caulk that contains silicone and resists mildew. If not, 100% silicone caulk is fine to use.
Is there a paintable silicone?
Paintable Silicone combines the superior adhesion and durability performance of 100% silicone with the paintability of acrylic. While acrylic may be paintable, it breaks down in water over time and can shrink and crack, leaving gaps for water and air to seep through.

Can I apply a second coat of silicone sealant?
Do not apply caulking in excess. … Sometimes a second layer of caulk is required and will produce a neater surface instead of overfilling a crack with caulk. If caulking is to be applied over existing and previous sealed joints, removing old caulk is essential and need to be done carefully.
Can you do 2 layers of silicone?
Craig also recommends applying two layers of silicone. … This is when you can remove the masking tape while the silicone is still wet, leaving a perfectly clean and even band of sealant all around your tub or tray. Leave for 24 hours before using the bath or shower.

How do you get acrylic paint to stick to silicone?
As with most surfaces, you will need to prime the silicone before applying any sort of paint. I recommend this Liquitex primer from Amazon. It will prime the silicone base, and then allow the acrylic paint to properly stick to the surface. Without a good primer, the paint will run and not stick at all.
How do you keep caulk from cracking when painting?
Another method which I discovered while spraying is finish the woodwork first, then tape off the woodwork (or some may say trim) and finish the emulsion after. This way when painting the woodwork with gloss/satin etc ensure you cover the caulk creating a barrier preventing the emulsion from cracking.
