Waterproof paint is a protective film that bonds to walls and blocks water ingress. A transparent coating is usually thinner, keeps the surface appearance, and mainly repels moisture. Choose based on location; transparent systems suit exposed concrete or cement surfaces where the original look must be preserved.
Yes, after cleaning, drying, and repairing cracks. Porous concrete or cement may need a compatible primer. In Riyadh, Jeddah, or coastal humidity, choose UV-resistant products with flexible movement, and include expansion joints on large areas to prevent cracking.
Prices vary by product type, coverage, surface condition, and required primer. In Saudi Arabia, costs depend on moisture and UV resistance, brand, and application area. Compare square-meter coverage and specifications, and consider Matkel options for different budgets and project conditions.
Often yes, especially on new, porous, dusty, or loose concrete and cement surfaces. Clean the area, remove dust and weak material, then apply a compatible primer. This improves adhesion, ensures even coverage, and reduces peeling or bubbling after curing.
Lifespan depends on product quality, surface preparation, and sun exposure. In hot regions such as Riyadh or Jeddah, exposed roofs may need touch-up or recoating every three to five years, while protected walls often remain effective longer with proper maintenance.
