Technical TDS

CaliwelTM is an interior surface treatment that employs a natural antimicrobial agent - Calcium hydroxide - to protect the coating from odor and stain causing microorganisms for years after it is applied. Formulated with calcium hydroxide that has a long history of safe antimicrobial use, Caliwel incorporates proprietary Bi-Neutralizing Agent (BNATM ) to prolong its antimicrobial potency. When applied to walls and other interior surfaces, Caliwel provides a long-lasting and durable coating that protects the surface coating from common microorganisms.

Key Benefits
  • Protects surface coating from microorganisms such as odor-causing bacteria, mold, mildew algae and fungi for years after application
  • Eliminates existing mold infestations
  • Reduces staining from algae and fungi
  • Contains no volatile organic compounds (VOC) – a “green” product

Surface Preparation

Mold/Mildew On Surface – scrape/remove all loose material.

New Drywall - repair holes/cracks by patching with joint compound and sanding. Sweep and wipe with a clean damp rag to remove sanding dust.

Masonry/Concrete – must cure for 30 days before coating. Remove form-release agents.

Plaster – bare plaster must be cured and hard. Textured, soft, porous or powdery plaster should be treated with 1 pint household vinegar to 1 gallon of distilled water. Repeat until surface is hard. Rinse and allow to dry.

Wood – sand exposed areas to a fresh surface. Fill nail holes and other surface damage with wood filler or putty. Sand smooth.

Previously Painted Surfaces – remove all loose paint, dirt, chalk and damaged substrate. Clean thoroughly to remove wax, grease and/or oil residue. Scuff-sand glossy surfaces. Wipe with a clean damp rag to remove sanding dust. Stains from water, smoke, grease, ink, etc. must be sealed with a suitable stain-blocking primer.

Ceiling Materials – seal absorbent materials with suitable primer.

* CaliwelTM contains an antimicrobial active ingredient – Calcium hydroxide – that protects both the liquid coating and the dried coating's surface.


For interior use only.

Apply at surface temperatures between 45oF and 120oF. For the best results keep Caliwel at room temperature prior to applying.

Surface must be dry and at least 5oF above dew point.

Reducer: DO NOT MIX WITH TAP WATER OR ADD PAINT OR PAINT THINNERS. Such action may adversely impact biocidal properties.


Brushing – 5% maximum
Rolling – 5% maximum
Spraying – 10% maximum
Product is best applied by air-less sprayer. Avoid use of sponge roller or sponge brush. Due to rapid dry time of coating, only small areas should be brushed or rolled. CAUTION! When spraying, wear goggles and a high-efficiency particulate respirator. Caution-off the immediate application area to prevent others from coming into contact with spray mist.

Care must be taken to apply material at recommended mil thickness.

Box all containers of same color.

Do not shake. Stir GENTLY before use.

Apply only when temperature is 45oF-120oF and drying conditions are good.

Apply uniformly with minimal brushing or rolling.
