## Overview

Sikaflex Mortar Repair Sealant is a polyurethane-based, elastomeric paste designed to seamlessly blend with limestone and stucco surfaces.

Ideal for both vertical and horizontal masonry repairs, it ensures durable, professional-grade mortar restoration.

## Description

Is your brick wall showing cracks or gapping in its mortar? If left unattended, the damage will only worsen, as water infiltrates and expands. Fortunately, Sikaflex limestone mortar fix is the perfect solution. This polyurethane-based mortar repair and sealant is textured to blend seamlessly to rough, stucco-like surfaces. It features strong adhesion and superior elasticity to allow movement between surfaces, which helps prevent damage to the sealant and results in a stronger bond. Maximum depth of joint should not exceed 1/2-inch for optimal performance. It also hides imperfections from tooling that smooth sealants can't match, so your handiwork looks more professional.
