## Overview

Sikaflex Mortar Fix is a limestone-colored, polyurethane-based sealant designed to repair and seal mortar cracks and gaps. Its textured formula blends seamlessly with rough surfaces, offering superior elasticity to prevent cracking and tearing. Paintable and sandable after curing, it meets rigorous ASTM and federal standards, ensuring durable, waterproof protection for both vertical and horizontal masonry joints.

## 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.

## Features

- DESIGNED TO BLEND — Sikaflex mortar fix sealant is specially textured to better blend with rough, stucco-like surfaces, while the limestone color makes the blend seamless
- RETAINS EXCELLENT ELASTICITY — The one-component polyurethane-based elastomeric sealant cures to a flexible consistency, improving resistance to tears and cracking
- READY YOUR BRUSHES — Once cured, the sealant is paintable, stainable, and sandable, so it's easy to match the style of the surrounding features. Just be sure to use oil, water, or rubber-based paints
- SEAL OF APPROVAL — Sikaflex concrete sealant meets federal and industry standards for quality and performance, and is urethane-based to reduce production of radon for a cleaner environment
- DEAL FOR BOTH VERTICAL AND HORIZONTAL — Insert cartridge into any standard caulk gun to apply. Begins to cure on contact with atmospheric moisture. Allow up to 7 days for final cure
