How long does Xypex last?
How long does Xypex last?
Xypex products must be stored dry at a minimum temperature of 45°F (7°C). The shelf life is one year when stored under proper conditions.
What is Xypex waterproofing?
Xypex prevents the penetration of water and other liquids from any direction by causing a catalytic reaction that produces a non-soluble crystalline formation within the pores and capillary tracts of concrete and cement-based materials.
Can Xypex be painted?
Can XYPEX be applied over paint? Because the active ingredients in XYPEX penetrate into the concrete, a clean, bare surface is required. Painted surfaces must be stripped. This can be achieved with grinders (contact your local tool rental shop) or chemical strippers.
How long does it take for Xypex to work?
If backfilling takes place within seven days after the application, the backfilling material should be moist so as not to draw moisture from the Xypex coating. Xypex requires a minimum of 21 days of curing and crys- tal generation before the application of any paint or ep- oxy.
Does Xypex change the color of concrete?
A Xypex coating normally produces a grey-colored, cementitious surface. However, Xypex “White” is also available.
How is Xypex applied?
Using a trowel, mix one part clean water with six parts Xypex Concentrate powder by volume for 10 – 15 seconds. Lumps should be present in this mixture. Do not mix more than can be applied in 20 minutes.
How do you use Xypex?
Under normal conditions, it is sufficient to spray Xypex treated surfaces three times per day for 2 – 3 days. In hot or arid climates, spraying may be required more frequently to prevent premature drying of the coating. Wet burlap and some specialty curing blankets are also effective for curing.
What is negative side waterproofing?
Negative-side waterproofing is the application of a coating material to the interior or the ‘dry’ side of a foundation or wall. Its primary function is to create a barrier coat to stop water from leaking through the wall and keeping the space dry.
Is Xypex toxic?
Xypex is a non-toxic chemical treatment for the waterproofing and protection of concrete.
Is Xypex an admixture?
Xypex Bio-San C500 is a uniquely designed admixture for integral, long-term protection of concrete in harsh sewage conditions with high levels of H2S that cause Microbial Induced Corrosion (MIC).
How much Xypex is in a yard of concrete?
1.5 lb per sq. yd. 0.80 kg per sq. m.
What is Xypex dry PAC?
How do you make concrete waterproof?
How do you make concrete waterproof?
- Flexible external waterproofing system for concrete.
- Concrete admixtures for waterproofing.
- Swelling tapes seal joints.
- Can be reused as often as necessary: injection system for sealing joints.
- Waterproofing formwork tie holes.
How do I use xypex admix C 1000?
Directions for Use Xypex Admix C-1000 NF is added to the concrete at the time of batching. It is important to obtain a homogeneous mixture of Xypex Admix with the concrete. Do not add dry Admix powder directly to wet mixed concrete as this could cause clumping and thorough dispersion may not occur.
How do you use xypex?
Mixing
- Mix Xypex with clean water only (potable water that is free of salt and other deleterious materials).
- Mix Xypex powder into the clean water with a paddle on a slow speed electric drill (250 RPM) or with other equipment that ensures adequate mixing.
- Be sure that the quantity mixed can be applied within 20 minutes.
Does xypex change the color of concrete?
How do you mix xypex with concrete?
What is crystalline waterproofing?
Crystalline waterproofing is a process where the active ingredients in a crystalline product react with the free lime and moisture in the concrete to form crystals within the capillary system of the concrete.
What is xypex used for in concrete?
By preventing the intrusion of water, salt water, sewage, and most chemicals, Xypex helps protect reinforcing steel against oxidation and deterioration. How deep does the Xypex crystalline formation penetrate the concrete? READ
How deep does xypex crystalline penetration into concrete?
Independent testing measured the depth of Xypex crystalline penetration into a cast-in-place concrete block at 30 cm (approximately 12 inches). The test concrete sample was coated on the top surface with Xypex Concentrate and left outside the research laboratory in ambient temperatures for 12 months.
How do you use xypex modified?
Applied as a second coat, Xypex Modified chemically reinforces Xypex Concentrate where two coats are required and produces a harder finish. Where dampproofing is required, a single coat of Modified may be used as an alternative to a spray/tar emulsion.
Why choose xypex waterproofing?
Xypex does not require sealing, lapping and finishing of seams at corners, edges or between membranes. It is less costly to apply than most other methods. The Xypex crystalline system for concrete waterproofing is substantially different from traditional barrier products — like membranes and cementitious coatings.
