What is the difference between water-based and oily waterproof materials?

1.Water-Based vs. Oily Waterproof Materials

The key difference between water-based and oily waterproof materials lies in their composition, environmental impact, and application methods:

• Solvent Type:

  • Oil-based waterproof materials are insoluble in water and must be diluted using chemical solvents. These solvents release volatile organic compounds (VOCs), which can be harmful to health and the environment.

  • Water-based materials, on the other hand, are diluted with water and emit only water vapor during application, making them non-toxic and eco-friendly.

• Environmental Impact:

  • Oil-based products are less environmentally friendly due to the emission of VOCs.

  • Water-based products are safer and greener, ideal for indoor use and residential areas.

• Construction Requirements:

  • Water-based waterproof coatings can be applied to damp or wet surfaces, making them suitable for complex or humid environments.

  • Oil-based materials require a dry, clean base surface, which can limit their use in certain conditions.

2. How to Waterproof Rural Houses

Waterproofing is essential in rural construction to prevent dampness, leaks, and long-term structural damage. Here’s a step-by-step breakdown:

① Foundation Waterproofing

• Allow the foundation to fully dry before adding moisture-proof layers.

• Use cement mortar to level the surface, or dry-lay gravel and fill gaps with coarse sand.

• During backfilling, use a loose-fill and soak method, or add dry ash for tamping. This reduces ground moisture and enhances the waterproofing effect.

② Wall Waterproofing

• Rainwater often accumulates at the corners of walls and may seep indoors, especially during heavy rainfall.

• For thin walls, apply a layer of moisture-proof putty followed by a waterproof coating.

• Pay special attention to bathroom and kitchen walls. Adjust the height and thickness of the waterproof layer based on usage needs.

③ Roof Waterproofing

• Ensure the roof has a proper drainage slope, which should vary according to local rainfall.

• In regions with heavy rain, increase the slope to avoid water pooling.

• Use a combination of waterproof membranes and coatings for long-lasting protection. Don’t overlook sealing around vents, joints, or corners — these are common leakage points.
