Frequently Asked Questions

Can I Plaster a Fireplace?

While it is possible to plaster a fireplace, it is not advised and may only cause more damage. Plastering a fireplace can lead to water infiltration and eventual collapse of the structure. Additionally, the mortar that holds the brick together may also fail due to moisture exposure. If you’re still considering plastering your fireplace, be sure to speak with an expert first in order to avoid any future complications.

Can You Plaster Over Bricks?

Generally, if the bricks are structurally sound and the plastering will not damage the bricks, then you can probably plaster over them. However, it is important to contact a professional before starting any plastering project as even small mistakes can lead to disaster.

What Plaster Should I Use in a Fireplace?

If you are using natural materials such as straw, hay, or wood to create your fireplace fireplaces, then plaster is not a necessary ingredient. However, if you’re using synthetic materials such as fiberglass or mortar boards, then plaster should be used in order to achieve the desired aesthetics and protection for your firewood.

Can Plaster Withstand High Heat?

Plastering with high heat can cause the material to shrink and warp, which may lead to deterioration or failure of your project. In some cases, this damage may not be evident until after the fact and will require extensive repair work that could cost more than originally incurred.

When working with plaster, always use a low-heat setting and exercise extreme caution when applying pressure in order to avoid damaging the material. Use a trowel instead of a brush if possible and position the board so that any excess moisture will run off rather than accumulate on it. Always check for signs of distress such as cracks or peeling before proceeding further down your design timeline.


To finish up, I recommend you use a thin layer of paint with sand mixed in to give the plaster some texture. This will help it feel more like actual brick and create an even smoother surface than paint alone. Once this is dry, seal it all off with two coats of water-based polyurethane to protect your work against future damage from spills or high humidity levels.

You might also want to consider adding decorative elements such as bricks or tiles before sealing everything off so that there are plenty of opportunities for artistic expression! This blog post has given helpful advice on how to plaster over brick fireplace.
