SikaTop 129 Sunshine

SikaTop 129 Sunshine is a two-component, pre-dosed, ready-to-mix waterproofing mortar with a low modulus of elasticity. It consists of a cement-based powder modified with special polymers and silica fume, containing aggregates of controlled grading and selected additives, as well as a polymer emulsion that imparts flexibility to the mix. It can be reinforced with alkali-resistant fiberglass mesh for waterproofing substrates subject to flexural stresses.

As a waterproof coating and final finish for surfaces in direct contact with water, such as swimming pools
For protecting concrete surfaces to increase their durability
For waterproofing and protecting hydraulic structures such as tanks, reservoirs, pools, and cementitious pipelines
As a flexible waterproof coating for reinforced concrete structures exposed to de-icing salts, freeze–thaw cycles, and carbon dioxide
For waterproofing and protecting balconies and terraces exposed to weathering
For waterproofed surfaces intended for pedestrian traffic (accessible areas)

High level of waterproofing performance.
Pre-measured packaging.
Resistant to substrate flexural stresses (that do not cause cracking of the substrate itself).
Vapour-permeable.
Very good adhesion to various substrates such as concrete, mortars, stone, bricks, etc.
Cures without shrinkage (no drying shrinkage).
Easy to apply even on vertical walls and ceilings.
