When we complete the process of tiling on a substrate and have reserved the joints between tiles, it is time for us to do grouting of joints.   While there are arrays of tile grouting or sealing products out in the market, have you ever wondered which choice would be the best?   Other than longevity, durability and appearance, we also have to bear eco-friendliness in mind. Partial amount of unqualified two-component tile sealants are composed of a high level of organic compounds which emit carcinogens such as formaldehyde and increase the carbon footprint.   Grouting powder is a safe, non-toxic, eco-friendly and ideal option to fill tile joints, with an ultra-easy application process.     Mix one bag of tile grout dry powder with potable water in accordance with the suggested water demand to achieve the desired consistency. Mechanical mixing with a slow speed drill and paddle is recommended. Apply the powder to the water and mix for about 5 minutes or until a lump free homogeneous mix is achieved. Allow the mix to stand for 3 minutes and mix briefly again just before use.     Apply the OPTIMIX TG410E using a rubber squeegee or rubber trowel to fill the joints in a diagonal motion. Vary the direction of the trowel passing over the same joint a few times and use light trowel pressure.     Once the grout surface begins to dry, then the grout and the surrounding tile surface can be cleaned. This should be done at regular intervals during the installation using a damp cloth or sponge.   Joints can be further smoothed using a gloved finger or with a pointing tool.   Then voila! It is done! OPTIMIX TG410E is a decorative high quality polymer modified cementitious mortar for tile grouting and joint filling. The product is strong, hard wearing and waterproof. It complies with the highest level of EN 13888 CG2 WA. OPTIMIX TG410E is available in a range of colours and textures to match most common joint widths, depths and architectural preferences.   Grade Recommended  Joint Width Recommended Depth TG410E – F (Fine Texture) 1mm – 6mm >3mm TG410E (Standard Texture) 3mm – 10mm >3mm TG410E – C (Coarse Texture) 5mm – 15mm >5mm If you have any questions regarding our dry mortar products, feel free to contact us today! https://www.optimix.com.hk/contact

This winter we are under the impact of an unusually cold weather, OPTIMIX sends our warmest regards in hopes that you are all safe and cozy at home. The last thing we need in this acute change in climate would be tiles popping up, imposing danger of injuries and the hassle of getting them repaired. In August we made a post discussing the importance of grouting to prevent this: https://bit.ly/3bQgyHk     The common reasons for tiles popping up are: 1. Plummeting temperature, expansion and shrinkage-caused movements in the substrate 2. Insufficient joint width between tiles.   For large floor tiles, we also recommend using our rapid-set DB390 & DB391 the Semi-Dry Bedding Mortar series. Utilizing the dry screed method, shrinkage and tile movement is much more stable with the DB screed, thus the risk of tiles popping and detachment is minimized, ensuring your safety even in extreme climates.   OPTIMIX DB390 SEMI-DRY BEDDING MORTAR (RAPID-SETTING) is a high quality rapid hardening screed designed for semi-dry bedding method of installation. OPTIMIX DB390 is simple to mix, easy to apply and has a reasonable working time to allow for rapid installation and quick return to service.   OPTIMIX DB391 ADHESIVE SLURRY (RAPID-SETTING) is a high quality polymer modified cementitious fast-setting adhesive. It is designed for rapid fixing and easy adjustment of floor tiles on traditional semi-dry bedding system. It is ready for grouting and can receive foot traffic in 6 hours after installation.     As a reference, after laying and leveling tiles, the ideal thickness of the adhesive should be about 3-5mm, the final thickness after application may be slightly reduced due to pressure. This thickness is sufficient to maintain the level of the entire floor tile system while avoiding hollowing. In order to prevent floor tiles from squeezing each other due to expansion, proper joint widths should be reserved during application.   If you have any questions regarding the installation of floor tiles, please feel free to contact us: https://www.optimix.com.hk/contact.

BOCHK Corporate Environmental Leadership Awards 2019 Prize Presentation and 2020 Launching Ceremony hosted by FHKI was successfully held on 5 October. Optimix has once again been awarded “Eco-Partner” certification for 3 consecutive years.   Optimix has always devoted in proposing and implementing new improvement plans on being environmentally friendly. In the process of handling raw materials and production, we hope to maximize each material’s use in every way. Plants in production process would produce some amount of dry mortar by-products, and with our past practice these by-products eventually might end up being industrial waste. In order to handle these by-products more effectively, we are now collaborating with national accredited contractors to recycle and further process them, giving these by-products a second life by turning them into materials like mechanical sand. Other than reducing industrial waste, we can also recycle and reuse these materials, ultimately reaching a win-win sustainable solution.   We stand by our rule to develop sustainably and one of our goals is to minimize the environment impact of our activities. We will also continue to search for innovative solutions, creating shared values for our customers and society.
