## Overview

MR VOLCANO Rigidizer 16oz Concentrate is a winterized colloidal-silica solution designed to penetrate and harden ceramic fiber insulation blankets like Superwool and RCF. When mixed 1:1 with water, it yields 32oz of tinted liquid for easy coverage verification. This product enhances fiber durability by creating an erosion-resistant surface that locks fibers in place, providing an ideal base for refractory coatings. Made in the USA, it withstands cold temperatures without freezing and is perfect for prepping forge, foundry, and furnace insulation for longer-lasting performance.

## Description

Get a tougher, more durable fiber liner—fast. MR VOLCANO Rigidizer is a colloidal-silica concentrate that soaks into ceramic fiber, cures to a firm surface, and helps reduce fiber disturbance under flame. It’s an easy, proven way to prep your liner before adding a thin refractory coat. The mix-1:1 formula makes 32 oz and is tinted so you can easily confirm full coverage.What people usually try — and why it falls shortRunning bare wool (no rigidizer): Uncoated fiber blankets are easily eroded by flame and handling. Solution: This rigidizer hardens the exposed surface to resist erosion and helps lock down loose fibers.DIY “waterglass” (sodium silicate) spray: Waterglass can form a glassy layer with relatively low softening temperature for forge interiors. Solution: A purpose-made colloidal-silica rigidizer is formulated for fiber linings in high-velocity flame environments.Skipping rigidizer and going straight to mortar: Applying refractory mortar to fluffy fiber can lead to weak spots and flaking. Solution: Rigidize first, then apply thin refractory coats for better adhesion and durability.Heavy castable layers: Thick castables add weight and thermal mass, slow heat-up, and reduce chamber volume. Solution: Rigidize the wool and keep refractory layers thin to preserve fast heat-up.Why this formula is easier in the shopMix 1:1 (makes 32 oz): Simple measuring and coverage. The red tint helps you see what you’ve hit—don’t use color as a dryness indicator.Freeze-resistant: Designed to resist freezing for better handling in cold conditions.Works with Superwool (AES) & RCF: Compatible across common insulation blankets used in forges, furnaces, and foundries.How to Use (summary)Prep the blanket: Lay out insulation, wear PPE, and lightly pre-wet with clean water (mist—don’t soak).Mix: Combine 16 oz concentrate + 16 oz water (shake ~45 sec).Apply: Spray or brush to fully wet all faces of the blanket (use the tint to verify coverage).Install & dry: Fit the blanket while still damp, then air-dry 24–48 hrs or run several brief, low-pressure heat cycles to drive off moisture before any refractory layers. Ensure it’s rigid and dry before coating.Tip: After rigidizing, apply thin coats of refractory (e.g., Satanite) and cure per instructions for a tougher hot face.Specs & CompatibilityType: Colloidal-silica rigidizer for ceramic fiber blankets/modules.Form: 16 oz concentrate → 32 oz when mixed 1:1 with water.Use on: Superwool (AES) & RCF blankets.Application: Spray or brush; freeze-resistant formulation.Made in USA.What’s in the Box(1) MR VOLCANO Rigidizer, 16 oz Concentrate (mix 1:1 with water to make 32 oz).

## Features

- Mr Volcano Rigidizer 16oz Concentrate - Winterized solution = Will not freeze in colder temperatures
- Locks down fibers & toughens your liner: Colloidal‑silica rigidizer penetrates ceramic fiber blanket to create a harder, more erosion‑resistant surface that helps keep fibers in place and provides a better base for refractory coatings.
- Simple mix, easy apply: Dilute the 16 oz concentrate 1:1 with water to make 32 oz; spray or brush onto pre‑wetted insulation. The solution is tinted so you can see coverage; dry by air or low, repeated heat cycles per instructions.
- Enough to cover 2x Mr Volcano Hero single burners or 1x Mr Volcano Hero 2 double burner forge.
- Great prep for refractory coatings: Common practice is: Wool → Rigidizer → Thin refractory mortar (e.g., Satanite) → Optional IR topcoat. A rigidized surface helps subsequent coats bond and hold up under flame velocity.
