and AASHTO M-235 specifications. Questions about Sikadur 35 Hi-Mod LV? Contact Us.

35 Hi-Mod LV may only be used by experienced professionals. Pressure-injection of cracks in structural concrete, masonry, wood, etc.

Gravity-feed of cracks in horizontal concrete and masonry. Epoxy resin binder for epoxy mortar patching and
overlay of interior, horizontal surfaces. Seal interior slabs and exterior above-grade slabs from water, chlorides, and mild chemical attack; also improves wearability.

SUBSTRATE PREPARATION:
Surface must be clean and sound. It may be dry or damp, but free of standing water. Remove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles and disintegrated materials. Concrete – Blast clean, shot blast or use other approved mechanical means to provide an open roughened texture. Steel – Should be cleaned and prepared thoroughly by blast cleaning.

MIXING:
Proportion 1 part Component ‘B’ to 2 parts Component ‘A’ by volume into a clean pail. Mix thoroughly for 3 minutes with Sika Paddle on low-speed (400–600 rpm) drill until uniformly blended. Mix only that quantity that can be used within its pot life. To prepare an epoxy mortar, slowly add 4–5 parts by loose volume of an ovendried aggregate to 1 part of the mixed Sikadur-35 Hi-Mod LV and mix until uniform in consistency.

APPLICATION METHOD / TOOLS:
To gravity feed cracks – Blow vee-notched crack clean with oil-free compressed air. Pour neat Sikadur-35 HiMod LV into vee-notched crack. Continue placement until completely filled. Seal underside of slab prior to filling if cracks reflect through. To pressure-inject cracks – Use automated injection equipment or manual method. Set appropriate injection ports based on system used. Seal ports and crack with Sikadur 31, Hi-Mod Gel or Sikadur 33. When the epoxy adhesive seal has cured, inject Sikadur-35 Hi-Mod LV with steady pressure. Consult Technical Service for
additional information. To seal slabs – Spread neat Sikadur-35 Hi-Mod LV over slab. Allow penetration. Remove excess to prevent surface film. Seal interior slabs and above-grade exterior slabs only.
