PERMERAL is a water clear, 36% solids, single-component, water-based urethane-acrylic sealer that adds an extra measure of abrasion resistance to floor surfaces.



PERMERAL provides a high gloss additional finish coating to better resist surface scratching. PERMERAL is a low viscosity, easy to apply, low odor sealer that can be used to restore the shine to worn or dull epoxy floor coatings. It can also be used as a low cost dustproofing sealer over clean, prepared concrete.

PERMERAL is typically applied in two thin coats between 500- 700 square feet per gallon per coat.

Limitations & For Best Results

  • Do not thin this product.
  • Do not apply when Humidity exceeds 70% indoors.
  • Do not allow to puddle during application.
  • Allow each coat to dry to 'tack-free' or clear prior to re-coat.
  • When re-coating, always apply the next coat within 24 hours of completing the previous coat.
  • PERMERAL only has a shelf life of 6 months from manufacturing date

Product Application

Apply using brush, roller and squeegee or via Hudson sprayer followed by back rolling. ROCK-TRED product test data is based on environmental temperatures of 75°F. Viscosity and working time are always affected by temperatures above or below that mark. When applying product always consider the ambient, surface, and product temperature at the time and place of installation.


Color and Textures

Permeral is only available in Clear and is not suitable to be broadcast with aggregate for texture.


Chemical Resistance

Always refer to ROCK-TRED's chemical resistance chart for specific information on each product / system or contact ROCK-TRED directly.


Product Storage

DO NOT allow ROCK-TRED products to freeze. All ROCK-TRED products should be properly stored above the floor on pallets or shelves, and in an area that has a constant minimum temperature of 50°F.


Surface Preparation

Always apply ROCK-TRED products to a clean / sound substrate that is free of laitance, grease, oils, debris, and curing compounds. Concrete substrates should be cured for a minimum of 28 days prior to application of product [except as otherwise noted on the individual Product Data Sheet]. Whenever possible, remove existing coatings and/or flooring systems completely; if complete removal is not possible always perform tests to determine adhesion and compatibility to the existing substrate. When coating over well bonded epoxy substrates mechanical preparation by means of a rotary sander is the best and recommended preparation method for PERMERAL applications. When applying directly to concrete the substrate must be clean. For best penetration to bare concrete preparation to a CSP-1 profile is recommended. If the substrate is not properly prepared and the appropriate profile is not achieved, failure of the product to adhere to the substrate may occur.


Clean Up

Application tools and equipment can be cleaned with soap and water immediately after use, or with solvent once the product has begun to cure.



Product containers will contain product residue and must be disposed of properly. Label warnings must be observed at all times. All containers must be disposed in accordance with federal, state, and local regulations.


Important Notice

Always read and acquaint yourself with ROCK-TRED's Product Data Sheet, SDS [safety data sheet], and product labels for each individual product prior to mixing and prior to use. For further assistance, product questions, additional information and/or unexpected or unusual installation conditions – contact your Area Sales Representative or ROCK-TRED directly for recommendations. Kit components are pre-measured for optimal performance. Catalyzation errors due to incorrect mixing in the field voids product warranty.
