• Free from aromatic compounds — stable under prolonged sun exposure
• Significantly enhances bond strength between mortar and substrates
• Improves mortar cohesion, strength, and flexibility
• Compatible with various cement mixes

Applications

• External wall rendering additive to prevent delamination
• Spatterdash bonding coat on smooth concrete surfaces
• Outdoor repair mortar for sun-exposed facades
• External wall leveling mortar additive

FAQ

EVA vs Bond Coat (SBR)?
EVA has superior UV resistance for permanent outdoor exposure on building facades. SBR (Bond Coat, Mulsibond) generally has higher bond strength and is versatile for indoor/outdoor general use. Choose EVA for sun-exposed exterior walls, SBR for general-purpose bonding.
