TechLevel-HPT High Performance Topping

TechLevel-HPT is a High Performance, Self-Leveling Topping designed for fast-track resurfacing and smoothing of interior substrates such as concrete, porous tile and certain non- porous surfaces when properly prepared. TechLevel-HPT can be sealed to create a concrete wear surface for commercial, light industrial and residential applications.

TechLevelHPT can be installed from 1/4” to 1” in one application. TechLevel-HPT is pourable and seeks its own level to produce a smooth, flat, durable surface that hardens quickly and dries fast

Conformance to Building Codes

Installation must comply with the requirements of all applicable local, state and federal code jurisdictions.

Composition of Product

TechLevel™ HPT is a proprietary dry blend of copolymers, cements, and inorganic chemicals.

Suitable Substrates

  • Properly prepared concrete
  • Existing ceramic/porcelain tile
  • Cementitious and epoxy terrazzo

General Surface Prep

USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when handling product.

All surfaces must be structurally sound, clean, dry and free from contaminants such as grease, oil, dirt, dust, curing compounds, waxes, sealers, efflorescence, or any other foreign matter. Concrete must be fully cured and absorb water. Approved substrates must be mechanically profiled and prepared by shot-blasting, scarifying, diamond grinding or other engineered approved methods to achieve a CSP #3 (reference ICRI CSP 3 standards for acceptable profile height).

CUSTOM® products may be used in assemblies over concrete with high moisture vapor emission levels provided that other materials such as sealers, coatings, finish flooring, adhesives or membranes are approved in these conditions. Consult the manufacturers for their limitations and requirements. Additionally, any sources of moisture are to be limited to initial concrete placement and not from sources such as water intrusion or from a lack of an effective vapor retarder/barrier.

For concrete with high moisture vapor emissions, apply Custom TechMVCTM Moisture Vapor and Alkalinity Barrier. prior to placing topping. See Priming section below regarding sand broadcast to rejection method when grinding or polishing TechLevel-HPT.

For additional questions about proper substrate preparation, call Custom Technical Services.

Additional Note: Substrates must be cured sufficiently when coatings are to be applied to the topping surface. Always perform a mockup to confirm acceptance of final appearance.

Movement Joint Placement

Joints or Cracks in Substrate

Expansion joints and construction joints that are designed to move are to be carried from the substrate up through the topping and filled with an appropriate elastomeric sealant. Failure to do so may cause hairline cracking and possible delamination.


For use as a wear surface over a shot-blasted surface, use a single coat of TechPrime™ E 100%-Solids Epoxy Primer or Custom TechMVCTM Moisture Vapor and Alkalinity Barrier with clean and dry #30 silica sand broadcast to full rejection while primer is wet as the priming system for TechLevel- HPT. After primer has cured, thoroughly vacuum excess sand from cured surface. Refer to the individual product data sheet for mixing and application instructions.

Health Precautions

See Safety Data Sheet for complete safety information. This product contains Portland cement. Avoid eye contact or prolonged contact with skin. Wash thoroughly after handling. If eye contact occurs, flush with water for 15 minutes and consult a physician. Use with adequate ventilation; do not breathe dust and wear a NIOSH approved respirator. If ingested, do not induce vomiting; call a physician immediately. Conformance to Building Codes Installation must comply with the requirements of all applicable local, state and federal code jurisdictions.

Limitations to the Product

  • For interior use only. Ambient, substrate and product temperature is to be between 50° F (10° C) 90° F (32° C). Chill or warm water when needed to make mixture fall between these temperatures.  
  • Substrate must be suitable for project usage.
  • Do not use on sloped surfaces that require drainage.
  • Precautions regarding excessive substrate deflection should be taken when applying over post-tensioned concrete, pre-stressed concrete or prefabricated concrete planks.
  • TechLevel-HPT is a cement-based product and may require a suitable sealer, coating or paint for protection depending on service usage. The application of wax or polish in addition to a sealer may help to preserve the surface. Such materials will need to be reapplied on a regular basis.
  • Sharp, rough and hard steel objects can damage cement based toppings such as TechLevel-HPT. Use protection boards for hard wheeled traffic and heavy equipment.

Bonding to Concrete Surfaces

In addition to general surface preparation requirements listed above, concrete must be free of efflorescence and hydrostatic pressure. Concrete surfaces must have a tensile strength in excess of 200 psi (1.4 n/mm²). Concrete that was treated with curing compounds must be evaluated for suitability or mechanically removed.

Mixing Ratios

Mix the entire 50 lb. (22.68 kg) bag of powder with 5 - 5.25 quarts (4.7 -5 L) of clean, cool water.

Mixing Procedures


Mix 50 lb. (22.68 kg) bag of powder with the appropriate amount of clean, cool water. Slowly add powder to water while mixing with a heavy-duty 1/2" (13 mm) electric drill and an “egg­beater” mixing paddle at minimum 650 RPM. Thoroughly mix for 2 minutes to a lump- free consistency. Do not overmix. Overmixing or moving the mixer up and down during the mixing process could trap air, which could shorten the pot life or cause pin holing during application and curing.

Application of Product

Pour the mixed product and spread with a long-handled gauge rake to the desired thickness. Directly after the topping has been dispersed, use a smoothing blade to break the material’s surface rheology and blend any inconsistencies to create a more uniform or homogeneous appearance. Keep a “wet edge” when pouring multiple mixes in the same area.

*** Always install a test area to confirm proper bonding as well as a desired appearance.

IMPORTANT NOTES: Self leveling cement based products may exhibit slight cracking due to structure and substrate moment; shrinkage; and creep. Sharp or reentrant wall corners can contribute to crack formation. These cracks are considered normal. Other causes of cracking are due to high ambient or substrate temperatures; wind or air flow; water ratios and mixing technique. When surface is sealed with clear or semi-transparent coatings, these cracks may become more visible.

Raw materials are naturally colored and therefore variations in colors should be expected. Mix batches from various pallets to achieve a more consistent color. Final finish color consistency can also be affected by water, wind, mixing, air flow etc., when being left as a wear surface.

Curing of Product

TechLevel-HPT is typically ready for water-based applied coatings after 4-6hrs. For epoxy and other moisture intolerant coatings at least 24hrs in moderate climatic conditions is typically required. See manufacturer's recommendations and confirm during mock up.

Install non-moisture-sensitive ceramic tile or stone in 4 hours; all other floor coverings should be installed after 16 hours Cure time can vary with temperature and humidity. Confirm moisture limitations of flooring and adhesives before installing over leveler.

Cleaning of equipment

Clean with water before material dries.

Product Maintenance

Properly installed product requires no special maintenance.
