Using Thompson's Water Seal On Camper Flooring: Is It Effective?

Thompson's Water Seal is a waterproofing product with a variety of applications. It can be used on wood, brick, stone, and concrete. However, it is not suitable for all surfaces, and users should be cautious about its compatibility with specific materials. For example, Thompson's Water Seal is not recommended for use on camper flooring or canvas. While some people have used it on their campers, it is not designed for this purpose and may not provide effective waterproofing. Additionally, it should not be used on painted surfaces or before plastering. It is crucial to properly prepare the surface and follow instructions for the best results.

Thompson's Water Seal is not suitable for interior applications

Thompsons Water Seal is not suitable for interior applications. The product is designed for exterior use only and should not be used on indoor surfaces. This is because the seal has a high linseed oil content, which can cause off-gassing and a lingering odour. It is also not recommended for use on wood that will be painted over, as it will negatively affect the adhesion of paint.

Additionally, Thompson's Water Seal should not be used to seal porous surfaces or as a bonding agent to increase the adhesion of plaster. It is intended for use on bare and uncoated brick, stone, or concrete. The product is not suitable for use as a damp-proof course, and it will not seal porous surfaces effectively.

Thompson's Water Seal is a waterproofing agent designed for outdoor use and is not suitable for all types of wood. While it can be used on exterior timber, it is recommended to use a dedicated preserver for the best protection against rot.

For interior applications, it is recommended to use a different sealer or finish more suitable for the specific type of wood or surface being treated. There are a variety of alternative products available that are designed for interior use and will provide a more suitable and effective finish.

It is important to follow the manufacturer's instructions and guidelines when using any sealing or finishing product. Always test on a small, inconspicuous area first to ensure the desired results and to check for any adverse reactions or effects.

It is designed for bare and uncoated brick, stone or concrete

Thompson's Water Seal is a waterproofing product that can be used on a variety of surfaces, including wood, brick, stone, and concrete. It is designed to protect these surfaces from water damage and enhance their appearance.

When it comes to using Thompson's Water Seal on camper flooring, there are a few things to consider. Firstly, it is important to note that Thompson's Water Seal is specifically designed for bare and uncoated brick, stone, or concrete. This means that it should not be used on painted or treated surfaces as it will not adhere properly and may not provide the desired level of protection. If you are considering using it on a camper floor, make sure that the surface is properly prepared and free of any coatings or treatments.

Additionally, while Thompson's Water Seal can be used on wood, it is important to note that its effectiveness may vary depending on the type of wood. For wood surfaces, Thompson's Water Seal offers a range of dedicated wood sealers that are specifically designed to protect exterior timber from rot and provide unsurpassed waterproofing protection. These wood sealers are specially formulated to penetrate the wood, providing maximum protection while also enhancing the colour and beauty of the wood.

Before applying any waterproofing product, it is crucial to properly clean and prepare the surface. This includes removing any existing stains, dirt, mildew, or other contaminants that may interfere with the adhesion and effectiveness of the sealer. Thompson's Water Seal offers a range of cleaning products specifically designed for exterior wood surfaces, ensuring proper surface preparation.

When sealing a camper floor, it is important to consider the potential for moisture buildup between the subfloor and the finish floor. While sealing the plywood subfloor can help retard moisture absorption and minimise odours, it can also trap moisture, leading to potential issues. Therefore, it is recommended to thoroughly evaluate the condition of the subfloor and consider using a breathable sealer or an alternative method for moisture management.

Overall, Thompson's Water Seal can be a viable option for sealing certain camper flooring surfaces, provided that the specific recommendations and limitations of the product are carefully followed. It is always a good idea to test the product on a small, inconspicuous area first to ensure desired results and compatibility with the flooring material.

It can be used on pitched roofs, such as sheds and outbuildings

Thompson's Roof Seal products can be used on pitched roofs, such as sheds and outbuildings. They are suitable for a range of roof surfaces, including slates, tiles, felt, and corrugated metal. The products are designed to protect exterior timber from the elements and provide waterproofing protection.

When using Thompson's Roof Seal, it is important to follow the instructions carefully for effective application and adhesion. The products are formulated to be water-based, reducing beading during the application process. After the initial application and rainfall, the surface may not show evidence of beading. However, as the treated surface weathers over a few days, beading will become more apparent, indicating the product's effectiveness.

It is recommended to test the product on a small, inconspicuous area first to ensure compatibility and desired results. Additionally, it is crucial to prepare the surface properly before application. The roof should be clean and free of any contaminants, such as mildew, dust, dirt, oil, soot, grease, or other substances.

Thompson's Roof Seal is designed to last up to four years, depending on factors such as the orientation of the roof and the local climate. Regular maintenance and reapplication may be necessary to maintain the desired level of protection.

It is not suitable for use on canvas

Thompson's Water Seal is a waterproofing product that can be used on a variety of surfaces, but it is not suitable for use on canvas. While some people have used it on their camper awnings with success, others have reported negative experiences. The product is designed for use on bare and uncoated brick, stone, concrete, and wood.

When used on canvas, such as tents, Thompson's Water Seal can cause the material to stick together, making it difficult to unfold. This is because the product contains a high amount of linseed oil and paraffin wax, which are not ideal for treating fabric. The wax causes the water to bead, but it wears away over time, requiring frequent reapplication.

There are other products specifically designed for resealing tent material and waterproofing canvas that would be more suitable and effective for treating camper flooring made of canvas. It is important to choose the right product for the specific type of fabric to ensure the best results.

Additionally, Thompson's Water Seal should not be used in interior applications or before plastering. It will not seal a porous surface and can negatively affect the adhesion of paint applied over it. The product is meant for outdoor use and is not suitable for all types of materials.

Therefore, while Thompson's Water Seal is a popular waterproofing option for certain surfaces, it is not recommended for use on canvas camper flooring due to its potential negative effects and the availability of more suitable alternatives.

It is not suitable for use on linoleum

Linoleum is a popular flooring option for campers, especially those seeking a wood-like aesthetic. While sealing the plywood floor beneath the linoleum is often recommended to preserve the wood and create a solid surface, it is important to consider the suitability of different sealants. Thompson's Water Seal, a well-known waterproofing product, may not be the best choice for this application. Here's why it is not suitable for use on linoleum flooring:

Incompatibility with Linoleum:

Thompson's Water Seal is specifically designed for use on exterior surfaces such as wood, brick, stone, or concrete. The manufacturer does not recommend its use on interior applications or porous surfaces. Linoleum, being an interior flooring option, would not be an ideal surface for this product.

Potential Adhesion Issues:

The hydrophobic properties of Thompson's Water Seal can negatively affect the adhesion of any subsequent coatings or finishes. This means that if you apply Thompson's Water Seal to the plywood subfloor and then attempt to glue down linoleum flooring, the sealant may interfere with the adhesion of the glue. This could result in an inadequate bond between the linoleum and the subfloor, leading to potential issues with the flooring over time.

Overapplication and Off-Gassing:

Thompson's Water Seal is designed to penetrate the surface it is applied to. When used on certain types of wood, such as plywood, there is a risk of overapplication, where the product cannot fully penetrate the surface and may puddle. Additionally, some users have reported off-gassing or a strong odour from the sealant, which could be problematic in the enclosed space of a camper.

Alternative Options:

There are alternative sealants available that are more suitable for use under linoleum flooring. For example, you could consider using a water-based polyurethane floor finish, which provides waterproofing without the same adhesion issues as Thompson's Water Seal. This type of finish is easy to apply and does not require the same level of surface preparation. Another option mentioned in the forums is West System epoxy, which is known for its durability, although it may be more expensive for larger areas.

In conclusion, while Thompson's Water Seal is a recognised waterproofing product, it is not the best choice for sealing a camper's flooring before installing linoleum. The potential issues with adhesion, overapplication, and off-gassing make it less than ideal for this specific application. Instead, opt for sealants or finishes specifically designed for use under linoleum or interior flooring to ensure a successful and long-lasting installation.
