Seal Hair Application

Seal Hair Application

Seal Hair Application Process

CONCRETE SURFACE PROCESSING & PREPARATION

Using proper protocol for casting, curing and processing your concrete will give you the best results. Concrete must be Clean and DRY for successful results.

A calibration step is required for all new users and recommended before using Seal Hair on finished projects.

Seal Hair is intended for industrial use by trained professionals, and is not intended for use to the general public.

Polished Concrete

  • Wet polish concrete up to 100-grit resin pad followed by a scotch bright pad.

  • Cut a piece of scotch bright using a 5” backer pad as a template.

  • Wet polish concrete to remove casting release, efflorescence, and haze.

  • The scotch bright will open the concrete surface and even out the color.

Important:

  • Dry polishing with sandpaper only is not recommended.

  • Concrete must be completely dry after wet polishing.

  • Minimum 48hrs drying after wet polishing recommended.

  • Use a roofing torch to check for moisture before applying sealer.

Cream Finish Concrete

  • Wet polish concrete with a 200 resin pad followed by a green scotch bright pad.

  • Dry polishing alone is not recommended.

  • Cut a piece of scotch bright using a 5” backer pad as a template.

  • Wet polish to remove casting release, efflorescence, and haze.

  • Scotch bright opens the surface and evens color.

Notes:

  • Works best with new casting surfaces such as melamine molds.

  • Reusable casting surfaces may leave lines or scratches.

  • Uneven concrete may require additional polishing.

  • Casting marks may show after sealer is applied.

  • Primer helps even out imperfections.

Curing and Drying Concrete

  • Allow proper airflow above and below concrete.

  • Concrete must be completely dry and moisture free.

  • Curing varies based on climate, humidity, temperature and environment.

Moisture check:

  • Use roofing torch.

  • If water vapor chases away from flame there is too much moisture.

  • Lightly torch surface left to right.

  • Allow surface to cool to 75 degrees and repeat.

Once clean and dry:

  • Allow surface to reach room temperature (about 75 degrees).

  • Shop environment must remain about 65F minimum after sealer is applied.

Safety Note:
Solvent based sealers are flammable. Never torch concrete near open sealer.

Acid Etching

  • Lightly acid etch concrete for best results.

  • Use muriatic acid designed for masonry.

  • Dilute based on acid percentage listed.

Example:

  • 32% acid → dilute 32:1 (Water : Acid)

Process:

  • Scrub with diluted acid using scotch bright pad.

  • Wash for about 2 minutes.

  • Surface should feel like 400 grit sandpaper.

Best practice workflow:
Polish → Acid etch → Grout → Polish → Acid etch → Dry → Seal

Calibration Step

Purpose:

  • Understand your environment.

  • Set curing protocol.

  • Check adhesion and processing steps.

Process:

  • Make new sample pieces using production workflow.

  • After sealer cures minimum 48hrs:

    • Cut concrete with grinder and tile blade.

    • Check cut for adhesion.

    • Core drill hole and check plug.

    • Razor blade checkerboard test.

    • Carpet tape pull test.

Sealer should remain bonded.

Do not use old samples. Test must match production conditions.

Color Enhancement Calibration

  • Seal Hair enhances color more than water based sealers.

  • New showroom color samples required.

  • Casting marks show more prominently.

  • Dry polishing alone is not recommended.

For cream finish concrete:

  • Mold must be clean.

  • Remove silicone lines and casting marks.

  • Use scotch bright with air polisher.

Prime Hair helps maintain natural look.

Grout Slurry Calibration

  • Solvent sealers enhance grout color more.

  • Use lighter color grout than water based systems.

  • Start with same loading as face coat.

  • Reduce color up to 25% if needed.

  • Create grout chart using sample sections.

MIXING

Mix the Sealer

  • Mix ratio 4A : 1B

  • Thoroughly mix Part A first (matting agent separates).

  • Use pneumatic drill and paddle mixer.

  • Mix slowly to avoid splashing.

Process:

  • Measure Part A using disposable cup.

  • Measure Part B using syringe.

  • Mix A and B together 3 to 5 minutes.

  • Dwell 5 minutes.

Safety:
Do not use electric or battery drill. Solvent based sealers are flammable.

Dilution

  • Dilute mixed sealer 2:1 ratio or 50% solvent.

  • Xylene or MEK recommended.

Accelerate Hair

  • Add 1ml accelerator to 130ml sealer.

  • Ratio based on sealer before dilution.

Temperature Requirements

  • Minimum shop temperature 65F.

  • Target surface temperature 75F.

  • Infrared heat lamps recommended.

  • Heat surface 1 to 2 hours after application for maximum performance.

COVERAGES CHART

Basic Calculation

  • Multiply sq/ft by 12ml.

Example:

10 sq/ft × 12ml = 120ml total sealer

Split ratio:

  • Part A = 96ml

  • Part B = 24ml

Add solvent:

  • 120ml ÷ 2 = 60ml solvent

  • Total mixed = 180ml

Coverage Guidelines

  • Minimum 2 mil film thickness required.

  • Typical range 12ml to 15ml per sq/ft.

  • Primed surfaces need less.

  • Raw concrete needs more.

DO NOT OVER APPLY SEALER.

Two thin coats only.

Metric Conversion

  • 125ml per sq/meter.

  • Smooth surfaces: 100ml Part A + 25ml Part B.

  • Rough surfaces: up to 132ml Part A + 33ml Part B.

Dilution always 50%.

SEAL HAIR APPLICATION PROCESS

Roller Application (Two Coats)

Equipment Needed

  • ¼” nap 6” stick roller
