Water-washed stone is a construction technique that has been increasingly popular in recent years. It primarily involves mixing natural river or sea pebbles or gravels with cement in a proportionate manner and applying the mixture to the base. After using a load-bearing tool to flatten it, the surface adhesive is treated, revealing the original appearance of the stones.

Due to the diverse colors and shapes of its raw materials, it can be used to create various patterns and designs, widely applied in interior decoration and outdoor landscaping. Some large-area exterior wall renovations also use water-washed stone, exuding a natural and simple feel.

Cautionary Notes:

Be mindful of the washed stone content; too little can result in an unappealing appearance, while too much may lead to loose bonding. For particles ranging from 3-5mm, an optimal content per square meter is around 18-20kg.

2. Mix gravel and cement thoroughly before adding water. Clean all debris from the concrete sublayer before laying to prevent loose碎石 from becoming unfastened and cracking.

3. The water-washed stone surface layer can be connected to other paving materials with copper strips or PE separation strips, ensuring the integrity of the water-washed stone edging.

4. When flattening, use a trowel to gently tap and smooth the mixed slurry repeatedly. Ensure thorough bonding between the mixed slurry and the base layer for even stone distribution. Outdoor construction temperatures should not be below 4°C to prevent bonding and curing issues, which can lead to easy detachment.

5. Clean the surface with a sponge promptly when it's semi-dry, and repair the stone aggregates.

6. Ensure timely protection of the finished product. Once fully dried, apply water-based resin to achieve waterproof, stain-resistant, and brightening effects.

Water-washed stone precautions

The cement grade used in washed stone generally exceeds 425.

2. Upon arrival at the site, the gravel must be inspected to ensure minimal color variation, minimal debris, and full grains.

After all the pebbles are coated and patched, a roller can be used for leveling and compacting the large area.

The color powder added to the cement is a UV-resistant powder to prevent discoloration of the stone pavement after a long period of time due to water washing.

The outdoor temperature during construction should be above 5 degrees Celsius to prevent hollowing and falling off.
