APPLICATION GUIDELINES

Surface Preparation

Initial Cleaning

    • Proper initial cleaning of your substrate includes removing dirt, contaminants, and debris from existing surfaces. All loose contaminants that could prohibit proper adhesion of the Ames Blue Max Tile – Liquid Membrane to the substrate can normally be removed with a stiff bristle broom, vacuuming, or other means unless the buildup is severe.

Inspection of Substrates

    • Inspect substrate for suitability to proceed with Ames Blue Max Tile – Liquid Membrane.
    • If there are substrate issues bring these issues to the project supervisor, architect, customer, or Ames Research Labs Tech Services attention for recommendations.

Substrate Conditions - are specific to the type of surfaces you are working on. Incorrect conditions can cause installation deficiencies that could affect the performance of your waterproofing installation.

Inspect Substrates for:

    • Protruding or missing fasteners
    • Loose or broken backer board
    • Excessive gaps between backer board panels
    • Excessive gaps at intersections of backer board to other adjacent items
    • Excessive gaps at cutouts for water pipes, shower heads
    • Rough sharp ridges in mortar sloping material
    • Dried crumbs of mortar slag on the surface of the shower base.
    • Mortar blocking mounting holes between Drain Base and Clamping Ring
    • Presence of mold or mildew on walls or sheathing due to extended exposure to the elements or other pre-existing conditions.
    • Wood Moisture content – at or below 20% as tested at core of substrate. This will typically be a consideration when the floor sheathing has been properly pre-sloped and is the intended substrate for the Blue Max Tile Waterproofing membrane.
    • For remodeling projects, a guideline for all types of existing substrates being protected with Blue Max Tile - Liquid Membrane Waterproofing is that aged materials need to be inspected for any possible need to repair or replace before proceeding with new applications. Structural and Environmental integrity is important in the underlying material as it will become a base for the new Ames Waterproofing System. An example of when aged and otherwise deteriorated substrates may be encountered could be when an aged existing shower or tub is being removed and a tile system is being installed.
General Guidelines
    • Blue Max Tile – Liquid Applied Membrane meets requirements of ANSI 118.10 and uniform plumbing code. Since Blue Max Liquid Membrane is part of a series of components making up your shower, we remind you to make sure you are in compliance with all current local plumbing codes and regulations in your area.
    • Document application conditions before, during and after completion of the waterproofing project to meet any required warranty conditions. (see Blue Max Tile waterproofing warranty instructions)
    • We always recommend a spot adhesion test of materials be conducted on site after surface preparation and cleaning has taken place. This is to verify dis-bonding issues do not exist and conditions are correct to proceed with installation.
    • The architect, engineer, owner, or building contractor may require a physical mockup be prepared at the jobsite to establish conformance with written installation standards are understood and will be met. This is not always the case but should be checked into as some projects have requirements related to jobsite mock-ups.
    • If a mockup is required (for example in a new apt. building) some customers will accept the installation of one shower unit as a mockup.
    • It is important to use your mil comb during application to prevent over or under application rates.
      • If material is under applied, then your Blue Max Waterproofing System will have insufficient film build to perform properly.
      • If material is over applied, then material will cure slowly and extend re-coat times.
        • Always remember that material performance is based on proper thickness of coatings and can be easily controlled during application using a mil comb.

Application Temperatures & Curing

    • Coordinate schedule to apply materials prior to high heat of the day. Best temperature range for application is 50º to 90ºF (10º to 32ºC) When working in colder temperatures apply a test patch to observe maximum millage that can be applied per coat without sagging.
    • Minimum temperature of 40 ºF (5 ºC) and rising before applying.
    • Plan application to avoid inclement weather for 24 hours after application in cooler climates or if rain is predicted.
    • Dry times are dependent upon the thickness of application, humidity, and weather. Product should be dried and cured after 24 hours. Low temperature, high humidity, and morning dew (condensation) can delay start times and increase drying and curing times.
    • Always test the coated surface after initial cure to determine if cooler temperatures and high humidity may have slowed down the drying time before beginning a second coat.
    • When material applied is dark blue, firm to the touch and slightly tacky the material is cured sufficiently for subsequent coats or application of finishes.

PRE APPLICATION DETAIL WORK

After the above general application tips and guidelines have been performed, a detailed inspection of the application area must be performed before beginning any work in the installation process. This can be done independently or with your contractor. This is to ensure that your project conditions match with the Ames installations guidelines.


Detail Work

Procedures for Completing Detail Work
    • Additional reinforcing of the Blue Max Waterproofing System is recommended over joints, at penetrations through the walls, at raised threshold openings or curbs, at inside and outside corners, at transitions to dissimilar materials, at drain base flanges and at other job conditions that may exist on your project.
Backer Panel Joints Detail
    • Pre-fill joints over 1/8”, minor over cuts, around wall penetrations, and voids with Blue Max Trowel Grade or Blue Max Caulk.
Inside & Outside Corner Joint Detail
    • In the case of inside corners, changes in plane, over open gaps or cracks we recommend embedding 4” or 6” polyester fabric reinforcing at those areas.
    • Once a wet band of Blue Max material is rolled out on each wall or on each side of a joint or gap, lay the fabric into the wet material.
    • When inside corners are reinforced, it is easiest to embed the fabric on one side of the joint. Then wrap the fabric around the joint into the wet material on the second side using a 4” mini roller or a large bondo squeegee. The fabric is quite flexible so should wrap around the inside and outside corners easily.
    • Once the fabric starts to saturate with Blue Max material it becomes limp and flexible.
    • When initially placing the fabric, pull the fabric straight from each end as the fabric is placed into the wet material.
Wall Penetration Detail
    • Pre-fill gaps around items penetrating the wall then, embed a cut piece of fabric into a wet layer of Blue Max material.
    • In the case of a round pipe, a slight curve can be cut into one side of the fabric with scissors to allow the fabric to contact both the pipe and the wall while being embedded in wet Blue Max Liquid Membrane. Snip the fabric with scissors as needed to lay flat without trapped air and overlay the fabric with additional pieces as needed for a full seal.
    • The intent is to create a tight seal between the wall and the item penetrating the wall – such as a shower head pipe or trim rings at rough-in plumbing flanges.
    • If the fabric is placed in a crooked fashion creating wrinkles, either pull out the wrinkles from the outside edges of the fabric or pull off the fabric and re-position while wet.

APPLICATION PROCESS

After inspection, repair, prefill joints, corners and cracks, you can begin the application of Blue Max Regular Grade Liquid Membrane. Although most application process will only require two coats, please pay careful attention to mil depth and condition of your substructure.
