Ahoy matey! Based on your request for a 20L interior and exterior paint, I'd recommend the Dulux Rockgrip Acrylic PVA White Matt 20L for R749.99. As South Africa's most trusted paint brand, Dulux products offer excellent hiding power and durability both inside and out. The acrylic formula of this paint allows it to be washed repeatedly for easy cleaning. Plus, the flat finish helps hide minor surface imperfections. With 20 liters you'll have plenty for large interior surfaces like walls and doors plus exterior touches like woodwork. Savvy pick for all your painting needs! Let me know if you need anything else.
