In the realm of construction, Oxicrete emerges as a fascinating solution, imparting a unique stone-like or rusty iron appearance to cement surfaces. Applied to diverse structures such as dam structures, polymer-modified screeds, and mortars, Oxicrete stands out as a transformative coating, offering both aesthetic appeal and functional advantages.
The application of Oxicrete results in a coating thickness ranging from 3 to 6 mm, culminating in a smooth matte finish. Its allure lies not only in its visual impact but also in its potential to breathe new life into aging concrete surfaces. What’s more, it presents itself as a cost-effective alternative to Corten steel, making it a compelling choice for construction projects.
Before delving into the application process, it’s crucial to consider the preferable conditions for applying Oxicrete. The trifecta of ambient, material, and substrate temperature should dance within the 15-30 oC range. Storage of Oxicrete components in a cool area sets the stage for success. Additionally, maintaining the floor temperature at least 3 oC above the dew point is imperative both before and after application to ward off condensation and blooming on the surface.
The canvas for Oxicrete application is the concrete surface, and its preparation is paramount. Utilizing techniques such as grinding or light vacuum-contained shot-blasting ensures an optimal surface. Failure to prep adequately may jeopardize adhesion, leading to the demise of the Oxicrete coating. New concrete surfaces must boast a tensile strength of 1.5 MPa or more and be free from laitance, surface sealer, or curing membrane. Meanwhile, old surfaces demand freedom from debris, dirt, and unwelcome deposits.
The placement of Oxicrete unfolds like a carefully orchestrated symphony. The initial act involves applying a 1 mm scratch coat, allowing it to cure for a maximum of 48 hours at around 20 oC. Should this window be exceeded, abrading becomes the encore, paving the way for another coat. The subsequent movement sees the pouring of the Oxicrete mix, guided by a notched trowel to achieve the desired coverage rate. A protective shield against dampness and condensation is crucial, urging the recommendation to water the area for a minimum of four days.
Oxicrete’s curing time dances to its unique rhythm, dictated by the purpose of applications and ambient temperature. A seven-day ritual befits surfaces destined for heavy-duty traffic, granting them full chemical resistance. Meanwhile, pedestrians tread freely after a mere 12 hours, light-wheeled traffic gains access in 24 hours, and medium-wheeled traffic is welcomed after 48 hours.
The versatility of Oxicrete shines through in its myriad applications:
Oxicrete’s appeal extends beyond aesthetics, boasting a tapestry of advantages:
In conclusion, Oxicrete unveils itself as more than a construction material—it’s a transformative force, reshaping surfaces and leaving an indelible mark on the canvas of construction possibilities.
