FAQ
What is Trubuild SBR-PRO 334?
Trubuild SBR-PRO 334 is a styrene-butadiene rubber (SBR) latex admixture used for improving the waterproofing, bonding, and performance properties of cement-based mixes like concrete, mortar, and plasters.
How does Trubuild SBR-PRO 334 enhance waterproofing in cement mixes?
The SBR polymers in Trubuild SBR-PRO 334 form a flexible, water-resistant film within the cement matrix that fills pores, reduces permeability, and bridges minor cracks, thereby improving the waterproofing capability of the mix.
What are the key benefits of using SBR latex in waterproofing?
SBR latex admixtures like Trubuild SBR-PRO 334 offer improved waterproofing, enhanced bonding, increased flexural and tensile strength, reduced water absorption and permeability, and better resistance to freeze-thaw damage in cement-based systems.
How is Trubuild SBR-PRO 334 added to cement mixes?
Trubuild SBR-PRO 334 is used as a partial replacement for gauging water. It is first added to the water which is then mixed with cement and aggregates to prepare the SBR modified mortar or concrete.
What is the recommended dosage of Trubuild SBR-PRO 334?
The typical dosage of Trubuild SBR-PRO 334 is 5-10 liters per 50 kg bag of cement. However, the exact dosage may vary depending on the specific application and performance requirements.
Can Trubuild SBR-PRO 334 be used for external waterproofing?
Yes, cement mixes modified with Trubuild SBR-PRO 334 are ideal for external waterproofing applications like terraces, roofs, swimming pools, water tanks, and exposed walls to prevent water ingress and improve durability.
What substrates can Trubuild SBR-PRO 334 modified mixes be applied on?
SBR modified cement mixes can be applied on a variety of prepared substrates including concrete, brick, masonry, stone, and wood. The latex improves the adhesion and bonding of the mix to the substrate.
Is Trubuild SBR-PRO 334 suitable for repair and restoration works?
Yes, Trubuild SBR-PRO 334 is recommended for repair mortars, floor screeds, and re-profiling works where good bonding, waterproofing, and durability are essential. It makes repairs more effective and long-lasting.
How does Trubuild SBR-PRO 334 improve the durability of cement mixes?
The SBR film formed in the cement matrix by Trubuild SBR-PRO 334 improves flexibility, reduces shrinkage cracks, and enhances resistance to wear, impact, weathering, and mild chemicals, thus improving the overall durability.
What precautions should be taken while using Trubuild SBR-PRO 334?
Ensure proper mixing and curing of SBR modified mixes. Protect the applied mortar or concrete from rapid drying due to direct sunlight or wind. Wash tools with water immediately after use.
