## Overview

Rutland High Heat Latex Sealant is a black, siliconized latex caulk designed to withstand extreme temperatures up to 800°F. Ideal for sealing stove pipes, chimneys, fireplaces, and wood stoves, it bonds multiple materials with flexible, waterproof durability. Trusted since 1883, this sealant resists cracking, shrinking, and combustion by-products, ensuring a long-lasting, professional-grade repair for your hearth.

## Description

Seal It Right is an easy to use sealant for installation and maintenance of direct vent appliances, such as gas burning systems and pellet stoves. Becomes tough and flexible with air curing and further hardens with heat. Resists vibrations, cracking, fumes, gasses, moisture and acids formed by gas combustion by-products. Due to its high solids content, it will not shrink or turn to brittle powder.

Review: The size of the container in the price. - Perfect size to adhere the rope on my outside stove. Would buy again from the seller.
Review: Works well at high temps - We used this stuff to seal our wood stove pipe and it definitely holds up to high temps. We only had a slight smell during the first burn or so, and a month later it seems to still be intact. Previously we had used stove cement, but that dried, cracked and fell off over time because it wasn't flexible enough for repeated expansion/contraction heat cycles.

## Features

- Built for Extreme Heat: This high temp adhesive withstands intense firebox conditions, making it a dependable choice whenever you ask what actually holds up near open flame
- Stove Pipe, Direct Vent and Stove Collar Sealing: Formulated as a high temp stove pipe sealant, it will withstand temperatures at the stove collar while remaining flexible; bonds metal stovepipe joints, wood stove seams, and even brick fire pit surrounds with a lasting seal
- Seal It Right Latex Fire Caulk: Functions as fire caulk and heat resistant putty for sealing gaps around fireboxes, flue collars, and damper plates that see repeated temperature swings
- Chimney and Fireplace Repair: Works as a chimney crown sealer and fireplace sealant; fills cracks and gaps where masonry meets metal so smoke and drafts stay where they belong
- Versatile Thermal Sealant: A black thermal sealant and heat resistant adhesive suited to fireplace repair, chimney leak sealer tasks, and general high heat caulk applications around the home and hearth

### ⭐⭐⭐⭐⭐ Works well at high temps
*by T***P on March 7, 2021*

### ⭐⭐⭐⭐ Improvement over silicone based caulk temp wise
*by J***. on February 10, 2017*

It is better than silicone because it can withstand a higher temperature - 800 F. I used it on my wood stove pipes, just above the stove. It has a nice black color and overruns clean up nicely with water immediately after you put it on. I used some when I put the pipes together, but I still had some leaks so I put a thick coating around the pipe seam areas. When my stove gets real hot I can smell the compound as it gives off a bit of an odor. As the pipe expands and contracts I have noticed that the seam of caulk cracks(even though there is some pliability to it) and I have to re-apply to spots. Not completely satisfied, but it is better than the less expensive silicone. On the other hand this stuff is not cheap either.
