However, there has been some concern about whether this product is harmful to plants. In this article, we will explore the potential toxicity of Thompson Water Seal to plants and how it can affect their growth.

What is Thompson Water Seal?

Thompson Water Seal is a clear, water-repellent sealer that is applied to wood, concrete or brick. This sealer creates a barrier that prevents water from penetrating the surface, which can lead to rot, mold and mildew. Thompson Water Seal is popularly used on decks, fences, and outdoor furniture to protect them from water damage.

Chemical composition:

Thompson Water Seal is made up of various chemicals in different formulations depending on the type of sealer. The main component of this sealer is a mixture of organic solvents and polymers that create a waterproof barrier. It also contains other chemicals such as resins, pigments, and biocides that protect the wood from sunlight and fungus growth.

Is Thompson Water Seal toxic to plants?

There is still debate on whether Thompson Water Seal is toxic to plants. The use of Thompson Water Seal on wood may cause the chemicals to leach into the soil, where they can be absorbed by plant roots. The effect of these chemicals on plants depends on the type of plants and the amount of exposure to the chemical.

One study found that plants exposed to Thompson Water Seal had reduced growth rates and a decrease in chlorophyll content. The results suggested that the chemicals in the sealer affected the plants' ability to obtain sufficient light, which reduced photosynthesis and growth.
