All surfaces must be clean, sound, dry, 50° F (10° C) and free of oil, gypsum compounds, wax, grease, sealers and/or curing compounds, urethane, paint, asphalt, loose surface material or any contaminate that will act as a bond breaker. Never use acid or mastic removers on any surface to which a Bostik product will be applied. Substrate must have a minimum direct tensile bond test reading of 74 psi per (ASTM C-1583-04). If sealers and/ or curing compounds are present they must be removed by mechanical means prior to application.

CONCRETE (TEXTURED, OPEN AND POROUS):

Preparation: Weak or contaminated surfaces must be cleaned down to solid, sound concrete by mechanical means such as shot-blasting, grinding or scarifying.

Priming: Apply one coat of Universal PrimerTM Pro diluted 50/50 (1 part water: 1 part Universal PrimerTM Pro) using a split tip broom. Pour out or spray liberally and work into surface, leave no puddles or bare spots. Apply SL-150TM once Universal PrimerTM Pro is dry (minimum 1 hour) and up to 24 hours. If primer has dried longer than 24 hours a second coat of Universal PrimerTM Pro will be required.

Thickness: 1/8" over the highest point. 1/4" up to 1" neat.

NON-POROUS (BURNISHED CONCRETE, TERRAZZO, CERAMIC AND QUARRY TILE):

Preparation: Mechanically abrade substrate to a dull finish with the use of a 60 grit or larger sandpaper, shot-blasting or grinding, vacuum or mop to remove dust.

Priming: Apply one thin coat of Universal PrimerTM Pro (Undiluted) using a 3/8" nap roller. Apply SL-150TM once Universal PrimerTM Pro is dry (minimum 2 hours) and up to 24 hours. If Universal PrimerTM Pro has dried longer than 24 hours a second coat of Universal PrimerTM Pro will be required.

Thickness: 1/8" over the highest point. 1/4" up to 1" neat, and up to 1" per layer of BostiMatTM.

EPOXY MOISTURE VAPOR COATING (Bostik's Slab-CoteTM, D-250TM or D-261TM)

Preparation: Sweep, vacuum, and wet mop to remove dust. DO NOT sand or abrade epoxy coating as this can compromise the performance of the coating.

Priming: Apply one thin coat of Universal PrimerTM Pro (undiluted) using a 3/8" nap roller. Apply SL-150TM once Universal PrimerTM Pro is dry (minimum 2 hours) and up to 24 hours. If Universal PrimerTM Pro has dried longer than 24 hours a second coat of Universal PrimerTM Pro may be required.

Thickness: 1/8" over the highest point. 1/4" up to 1" neat.

WOOD (REQUIRES BOSTIMATTM OR LATHE INSTALLATION)

NOTE: Wood must be a minimum 3/4", untreated, APA Rated, Type-1, exterior grade plywood. The subfloor must be free of deflection (maximum L/360), considering both live and dead loads. Use an approved anti-fracture membrane over SL-150TM where ceramic tile or stone are being installed.

Preparation: Prepare by sanding down to clean bare wood. Secure wood subfloor with deck screws and fill open seams with UltraFinishTM Pro, WebcreteŽ 98 and WebcreteŽ 95. Replace any weak or water damaged wood.

Priming: Apply one thin coat of SL-150TM (Undiluted) using a 3/8" nap roller. Apply BostiMatTM and SL-150TM once Universal PrimerTM Pro is dry (Minimum 2 hours) and up to 24 hours. If Universal PrimerTM Pro has dried longer than 24 hours a second coat of Universal PrimerTM Pro will be required.

  • Gauge rake
  • Smoothing tool
  • Measuring pail
  • Split-tip broom / 3/8" nap roller
  • 1/2" drill (minimum 650 rpm)

ADHESIVE RESIDUE (THIN, TRANSLUCENT, NON-WATER SOLUBLE, FREE OF TACK AND WELL BONDED)

Preparation: SL-150TM can be installed over thin (translucent) sound, non-water soluble adhesive residues that are free of tack and well bonded to the substrate. The adhesive cutback needs to be prepared using the wet scrape method as outlined in the Resilient Floor Covering Institute booklet "Recommended Work Practices for the Removal of Resilient Floor Coverings". Remove all patching materials below the adhesive and avoid applications where heat or excessive moisture will soften or degrade the adhesive.

NOTE: If unsure of the suitability, deflection or heavy loads are expected, use application listed below for very distressed subfloors.

Priming: Apply one thin coat of Universal PrimerTM Pro (Undiluted) using a 3/8" nap roller. Apply SL-150TM once Universal PrimerTM Pro is dry (minimum 2 hours and up to 24 hours). If Universal PrimerTM Pro has dried longer than 24 hours a second coat of Universal PrimerTM Pro will be required.

Thickness: 1/8" over the highest point. 1/4" up to 1" neat.

VERY DISTRESSED SUBFLOORS (REQUIRES BOSTIMATTM INSTALLATION): MUD BEDS, LIGHTWEIGHT CONCRETE, OVERWATERED CONCRETE.

Preparation: Remove all loose debris from subfloor. Sweep and vacuum substrate thoroughly.

Priming: Apply one coat of Universal PrimerTM Pro diluted 50/50 (1 part water: 1 part Universal PrimerTM Pro) using a split tip broom. Pour out and work into surface, leave no puddles or bare spots. Apply BostiMatTMand SL-150TM once Universal PrimerTM Pro is dry (minimum 2 hours and up to 24 hours). If primer has dried longer than 24 hours a second coat of Universal PrimerTM Pro will be required.

Thickness: 1/8" over the highest point. 1/4" up to 1" neat.

MIXING

Mix 2-bag batches of SL-150TM. For each bag add a maximum 5.5 quarts of clean cold water into a mixing barrel. Then, add bags of SL-150TM while mixing at full speed with a mixing paddle attached to a heavy duty 1/2" drill (min. 650 rpm). Mix for 2 minutes or until lump free. Add no additional water and keep the mixing paddle immersed in the material to avoid entraining excess air.

INSTALLATION

BarrelMixing: Pour the blended SL-150TM on the floor immediately and disperse with a gauge rake followed by finishing with a smoothing tool. SL-150TM will maintain its workability and healing for up to 15 minutes.

NOTE: During application and for first 24 hours prevent excessive air movement but maintain adequate ventilation and protect material from direct sunlight. These variables can cause uneven curing patterns, a false set, or cracking.

GENERAL GUIDELINE

FOR INSTALLING BostiMatTM WITH SL-150TM:

NOTE: Review the complete BostiMatTM technical datasheets as more detailed information may be required. The information below acts only as a general guideline and may vary based on jobsite conditions. After Universal PrimerTM Pro is dry to the touch simply roll out BostiMatTM over the properly prepared and primed surface. Overlap all seams a minimum of 1" and cut to fit using scissors. A single layer of BostiMatTM can be used to reinforce Bostik self-leveling applications up to 1" thick. Mat installation does not need to be wrinkle free as the product breaks down into individual fibers after the self-leveling is placed.

Place a minimum of 1/4" of underlayment over BostimatTM. Once the mat is covered, gauge rake and work the underlayment in a crosshatch pattern. A porcupine or agitating roller may be required to properly disburse the fibers. Finish surface with a smoothing tool. When barrel mixing, do not drag the barrels over the BostiMatTM. Bostik recommends the use of a hand truck, dolly or cart to transport material. A lane of masonite can also be laid from the mixing station to the placement area.

NOTE: BostiMatTM fibers should be visible on the surface of the cement after placement. Pouring or pumping the self-leveling back into already placed material will help in dispersing the fibers.

LIMITATIONS
