Download Tests of cement-water paints and other waterproofings for unit-masonry walls
A single-wythe concrete masonry wall may be a cost-effective structural element, but it can present challenges for waterproofing. The National Concrete Masonry Association (NCMA) recommends redundancy to keep concrete masonry walls dry through techniques at the surface of the wall, within the wall, and through adequate drainage systems.

Watch application procedures carefully. The manufacturer probably has a special procedure for treating voids, form-tie holes, and joints. At the wall-footing joint, you may be required to use cement or other trowel-grade material to form a "fillet" (radius or cove) before applying the overall coating.
Looks like I'm down to DryLoc (Latex based) vs. Behr WaterProofing Paint (Acyrlic) for painting my existing below grade (poured in place) concrete foundation wall.
Going to patch some of the tie rod holes with hydraulic cement first and then apply two coats of either Behr or Dryloc. After all repairs are complete, the walls or floors should be ready for cement waterproofing.
If the surface has been painted in the past, this paint may need to be removed in order for the water sealant to adhere to the concrete.
Sandblasting, wire brushing, or sanding are three ways to remove the old paint from the concrete surface. Krogstad, N.V.,Masonry Wall Drainage Test - A Proposed Method for Field Evaluation of Masonry Cavity Walls for Resistance to Water Leakage,Masonry: Components to Assemblages, ASTM STPJohn H.

CEMEX’s Masonry Cements are produced in Type N Masonry Cement, Type S Masonry Cement and Type M Masonry Cement strength levels for use in preparation of ASTM Specification C Type N, M or Type S Masonry.
Coatings are sprayed, trowelled, or brushed onto below-grade walls, providing a continuous barrier to water entry. Coatings should be applied to clean, structurally sound walls.
Walls should be brushed or washed to remove dirt, oil, efflorescence, or other materials which may reduce the bond between the coating and the wall.

Exterior surface of below-grade walls of basements & unvented crawlspaces finished as follows: a) For poured concrete, masonry, & insulated concrete forms, finish with damp-proofing coating. 6 b) For wood framed walls, finish with polyethylene and adhesive or other equivalent waterproofing.
Water-Managed Wall Assembly. So it is very important to test the soundness of cement. To test the soundness two methods can be applied. Le-Chatelier method; Autoclave method; 5. Strength Test. Cement has two types of strength – compressive strength and tensile strength.
To know the compressive strength and the tensile strength of cement following tests are performed –. There are two main field testing methods used for water repellency of concrete masonry units (CMUs), for quality assurance before being placed in a wall: droplet and RILEM tube testing.
Completed assemblies can also be tested with RILEM tubes or other standard water spray tests. ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates.
Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.

application to the masonry, masonry walls are required to have not less than 3/ 8 in. ( mm) portland cement parging applied to the exterior of the wall before applying damproofing. The following materials are specified in the IBC as acceptable TEK B Water Penetration Resistance (). There are various methods and performance standards tests that can be a deciding factor when demonstrating why a Sherwin-Williams concrete coating may be a better choice than a competitor's coating.
Download Concrete Coating & Substrate Testing Standards PDF. Check out our other educational sections: Concrete & Masonry Waterproofing is the formation of an impervious barrier over surfaces of foundations, roofs, walls, and other structural members.
The function of the impermeable barrier is to prevent water penetrations. The building surfaces are made water-resistant and sometimes waterproof.
The utilization of liquid waterproofing membrane, cementitious materials, polyurethane liquid membrane, and bituminous. sectors. Paint testing can be done in a number of different ways. The fact of the matter is that many industries use several different paint testing methods in order to ensure accurate results.
Paint should be tested in a wet form for particular properties but also in the dry form. Testing of paints. testing can provide useful information on the integrity and water-tightness of building envelope systems. In some cases, water penetration testing uses a calibrated apparatus to apply water to the test sample at specific flow rates and air pressures.
In other situations, water infiltration can be. Tex-Cote LLC - TEX•TURA® Interior / Exterior Textured Wall Coating Description: TEX•TURA® is a pigmented, textured seamless wall finish. It is used for new or renovation projects to provide a multicolor and texture coordinated wall finish.
The system is designed for. ASTM's masonry standards are instrumental in specifying, testing, and evaluating the basic units and materials used in masonry construction.
Such materials include mortar, asbestos, tiles, bricks, cement, aggregates, clay, concrete, fiber, and possible mixtures thereof that are used in conjunction with the erection of building structures. The ASTM C (Standard Test Method for Evaluation of Water Leakage Performance of Masonry Wall Drainage Systems) is a standard procedure for determining the ability of a masonry wall drainage system to collect water that penetrates the exterior wythe during rainstorms and direct this water back to the exterior via weep drainage systems.
The Lawn Ornaments and Fountains website recommends using an outdoor, latex paint for painting concrete fountains. Cleaning Before painting a cement water fountain it is important to remove residue from the surface of the fountain, according to the Refinish Furniture website.
Explanation of these two systems can be found under the Waterproofing tab. If you do not have water coming in from the first part of the test the next step would be to place the garden hose right against the foundation wall on the outside.
Go into your basement right away. Plain and Reinforced Unit Masonry (ASTM C) and should be performed by an accredited laboratory conform-ing to the Standard Practice for the Accreditation of Testing Agencies for Unit Masonry (ASTM C). As stated in Article B of the Commentary on Specification for Ma-sonry Structures (ACI /ASCE 6/TMS ) “ASTM.
Glass-unit masonry. Exterior walls of glass-unit masonry shall be designed and constructed in accordance with Chapter Plastics. Plastic panel, apron or spandrel walls as defined in this code shall not be limited in thickness, provided that such plastics and. consistency testing and testing to verify compliance with the property specification are covered in this TEK.
Field-prepared and preconstruction mortar should be evaluated using Standard Test Method for Preconstruction and Construction Evaluation of Mortars for Plain and Reinforced Unit Masonry, ASTM C (ref. 4), which includes the follow.
Spread out each plastic square flat over a dry area of concrete. Tape along all four edges of the square with duct tape or other waterproof tape. Firmly press the tape to create a moisture-tight seal with the plastic and concrete.
Use as many squares as needed to test all the main areas that may get flooring. Quality tests on cements at construction site (also called field tests on cement) are carried to know the quality of cement supplied at site.
It gives some idea about cement quality based on colour, touch and feel and other tests. Apply a thin, even coat of paint using a paint roller. Start in one of the corners, or at the top of you are painting a wall, and work slowly and evenly across the entire surface.
You don't need as much paint as you think in each layer -- you'll be adding more layers once the first is done drying, so don't try and slather it all on now. Views: K. Figure 1: Test walls for rain water penetration and leakage The test chamber was designed and built with reference to the specifications of the ASTM E (), the Project EPUSP/TEBAS () and the defined method in IPT ().
The test chamber was designed for easy handling and transportation and so. Step1: Mix cement paint and water in proper ratio. Take 2 parts of cement paint and one part of water and stir thoroughly. Take care to add cement paint gradually to the water and not vice versa.
Step 2: Add remaining water. Add remaining one part of water to the mixture. Step 3: Shake the solution. Stir the solution thoroughly to obtain. Concrete under hydrostatic pressure requires additional waterproofing methods to protect it from damage and deterioration.
Water repellents are also known as ‘hydrophobic’. These products typically come in liquid form and include oils, hydrocarbons, stearates or other. Paint dries to different thicknesses, or “mils,” depending on its sheen and makeup. The thicker the mil of the paint, the longer this process can take.
Paint applied to floors or walls in basements may have a longer curing cycle. After your final coat of paint is applied, allow the paint.
Test Method CMU-WR1 contains standard tests methods for water stream and water droplet tests of concrete masonry units. The purpose of these tests is to visually assess the water absorbency characteristics of the exposed surfaces of a hollow or solid concrete masonry unit when subjected to either a dynamically or statically applied source of water.
The other main standard for mortar is ASTM C, Standard Test Method for Preconstruction and Construction Evaluation of Mortars for Plain and Reinforced Unit Masonry. This standard contains a series of tests that can evaluate various properties of the mortar in the field.
Types of Paint for Masonry. Cement paint and other masonry coatings come in a range of types and, in many cases, a relatively narrow range of colors.
Each formulation is designed with specific performance characteristics. Exterior wall paints are available in .
