    If I use this over subflooring or vinyl flooring, will I still need to use hardy-board or concrete board when installing wood-look tile or can the tile be installed right over it?

  • Q:

    I have a 190 sf room that slopes about 2 inches from one side to the other. How do you mix pea gravel with the self leveling concrete so I don't need to use 30-35 bags.

    How much gravel can I add. Do I put the gravel on the floor and pour over it or do I mix it in with the self leveling concrete.

      A:

      For deep pours that require an increase in elevation
      from 1" to 5", SL-150 should be reinforced with clean dry pea
      gravel having an average diameter of 1/8" -3/8". Pea gravel
      should be mixed at 15 lbs. per 50 lb. bag of SL-150. Additional
      patching or smoothing may be required if pea
      gravel is added to the mix.

  • Q:

    How thick can this product be built up? Can it be used to level a slab where the fall was supposed to be 1/2 inch per 10 feet but it is 1 1/2 inch per 10 feet? The area would be approximately 8' x 8 '.

  • Q:

    Hi,
    How much water do I need to mix with 1 bag of self level cement ?

      A:

      Full "detailed" instructions come on each bag:
      MIXING
      Mix 51⁄2 quarts of water per 50 lb. bag of SL-150. Always measure
      the water added. Do not mix by feel. Always add powder
      to the liquid. Mix with a high-powered drill at 500-1000 rpms
      using a "Wagman WMP-30" or other appropriate mixing paddle.
      Mix to a liquid, creamy, lump free consistency. Spread as quickly
      as possible. For deep pours that require an increase in elevation
      from 1" to 5", SL-150 should be reinforced with clean dry pea
      gravel having an average diameter of 1/8" -3/8". Pea gravel
      should be mixed at 15 lbs. per 50 lb. bag of SL-150. Additional
      patching or smoothing may be required if pea
      gravel is added to the mix.
