SEMCO Liquid Membrane™

Preparation:

• 60 grit sandpaper

Normal application:

• SEMCO Liquid Membrane
  

Application in coves, corners or over cracks and sheeting:

• Fabric Reinforcement
  

For trafficable surfaces:

If you're installing our membrane as a finished coat, make sure it's sealed:

• Titan Shield Gloss

CLEAN SURFACE

• For bare concrete or water based coatings we recommend our Preparation D in order to remove any mineral deposits or efflorescence from the surface. For this you will need the following cleaners: Nu-Lift Cleaner and Stone Soap
  
• For concrete surfaces with oil stains or grease we recommend Preparation
  B. For this you will need the following cleaners : Power Cleaner and Stone Soap
  
• Ensure your surfaces are fully cleaned and dried. Gather all the products and
  tools needed for your project.

FABRIC REINFORCEMENT

If you have any cracks wider than 6mm, a Fabric Reinforcement is needed to bridge the crack. Any cracks smaller than 6mm width, SEMCO Liquid Membrane™ can be applied over it.

MASKING

Mask off areas that are not receiving any coating. Remove masking tape before material has fully cured.

• Use a 12mm nap roller. Allow any pre-treated areas to fully dry. Apply a thin coat (0.75mm per coat) of SEMCO Liquid Membrane™ with brush or roller over substrate including pre-treated areas.
• Once you can walk on the surface and not get any residue on your shoe or
  feet or cannot leave a fingerprint impression it is ready to re-coat.
• Apply another thin coat of SEMCO Liquid Membrane™ in an alternate direction over the first coat of SEMCO Liquid Membrane™.
• Let topcoat dry to the touch, approximately 1–2 hours at 70 °F (21 °C) and 50% RH.
• When last coat has dried to the touch, inspect final surface for pinholes, voids, thin spots or other defects.
• SEMCO Liquid Membrane™ will dry to a lighter color when it’s dry to
  touch. Use additional SEMCO Liquid Membrane™ to seal the defects. Required
  total thickness is 1mm for non submerged applications.
  

CURING TIME

• Curing time depends on temperature, humidity and airflow, however typically initial cure is within 6 - 7 days as per specific product recommendations.

• For clean up use warm water to clean brush or roller right after use.
• For optimal bonding we highly recommend preparing the surface as mentioned above for best results.
• Stir up the product well before use in order to mix up the color pigments.
• Avoid application in direct sun light in the afternoon or temperatures of over 30°C as it might cause the product to dry too fast before it can adhere to the substrate.
• To make your new Liquid Membrane surface trafficable, it must be sealed with our SEMCO Titan Shield Gloss sealer.
• It can not be applied to wet substrates or substrates still containing
  moisture, else it will not cure correctly and stay tacky. Max. rest moisture in
  substrate can be up to 3%. If you are unsure about the moisture content, have
  it measured prior to application.
• For applications where the product is fully submerged, 3 coats @1mm each is
  required and allow a curing time of minimum 6-7 days. Also application must coat entire surface to above the waterline.
• Cure times are displayed in our curing chart. However if coats have been
  applied too thick, the surface might feel tacky. This is a sign of trapped
  moisture. If you have left over product, apply a very thin coat over the entire
  surface. The surface needs to be fully cured and hard before permitting water.
• For applications where SEMCO Liquid Membrane™ is applied on pool plaster,
  extended curing times might occur as plaster holds more moisture which needs to
  breath out first. A slight color change may occur when being in contact with
  water when the product has not fully cured yet. This however will not affect
  the performance of the SEMCO Liquid Membrane™.
• It is always advisable to apply a small test patch in an inconspicuous are to
  ensure adequate adhesion prior to full application.

Preparation

• For concrete or gunnite surfaces we recommend our Preparation D. For this you will need the following cleaners: Nu-Lift Cleaner and Stone Soap
• For fiberglass surfaces it is required to sand the entire surface first with
  a 60 grit. Afterwards use Preparation B. For this you will need the following
  cleaners: Power Cleaner and Stone Soap
• If there is constant dampness in the substrate, use Natural Shield first to mitigate the moisture.

Normal application:

• SEMCO Liquid Membrane

Application in coves, corners or over cracks:

• Fabric Reinforcement

• Clean with Stone Soap

MASKING

• Mask off areas that are not receiving any coating.
• Remove masking tape before material has fully cured.

FABRIC REINFORCEMENT

• For any joints between the boards and the joint between floor and wall, we recommend using the Fabric Reinforcement. To apply the Fabric Reinforcement, apply a generous coat of SEMCO Liquid Membrane™ over the crack.
• Put the Fabric Reinforcement on and press it flat, after 10-15 min apply another coat of SEMCO Liquid Membrane™ over the Fabric Reinforcement to encapsulate it.
• Let it dry to the touch before applying SEMCO Liquid Membrane™ over the entire surface.

• Use a 12mm nap roller. Allow any pre-treated areas to fully dry. Apply a thin coat (0.75mm per coat) of SEMCO Liquid Membrane™ with brush or roller over substrate including pre-treated areas.
• Once you can walk on the surface and not get any residue on your shoe or
  feet or cannot leave a fingerprint impression it is ready to re-coat.
• Apply another thin coat of SEMCO Liquid Membrane™ in an alternate direction over the first coat of SEMCO Liquid Membrane™.
• Let topcoat dry to the touch, approximately 1–2 hours at 70 °F (21 °C) and 50% RH.
• When last coat has dried to the touch, inspect final surface for pinholes, voids, thin spots or other defects.
• SEMCO Liquid Membrane™ will dry to a lighter color when it’s dry to
  touch. Use additional SEMCO Liquid Membrane™ to seal the defects. Required
  total thickness is 1mm for non submerged applications.
  

CURING TIME

• Curing time depends on temperature, humidity and airflow, however typically initial cure is within 6 - 7 days as per specific product recommendations.
