Grey colour blends with concrete, stone, and most building substrates
Suitable for joints subject to moderate movement and thermal expansion
Das zeichnet Sikasil-108 Nature Matt aus
The neutral curing chemistry avoids the acidic by-products of acetoxy sealants, making it compatible with a wider range of substrates including metal, glass, and coated surfaces. The matte finish reduces visible seam lines and resists dirt accumulation better than glossy alternatives.
Ideal für...
Building contractors and tradespeople working on facade joints, window perimeters, and expansion joints in concrete and masonry. The 310 ml size suits both small repair tasks and medium-scale sealing jobs where a clean, low-profile finish is required.
Anwendung von Sikasil-108 Nature Matt
Clean the substrate thoroughly — remove dust, oil, and loose particles
Apply a continuous bead into the joint or gap using the cartridge nozzle
Smooth the bead with a spatula or finger dampened with soapy water
Allow 24 hours for skin formation; full cure depends on joint depth and humidity
