## Overview

MR VOLCANO Rigidizer 16oz Concentrate is a US-made, freeze-resistant colloidal-silica solution designed to penetrate and harden ceramic fiber insulation blankets like Superwool and RCF. Mixing 1:1 with water yields 32 oz of tinted rigidizer that visibly confirms coverage, creating a tougher, erosion-resistant surface that enhances refractory coating adhesion and extends forge liner lifespan.

## 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.
