Cold Weather Construction Solutions
As we move into the winter months, here are some products designed to perform in cold weather.
MasterEmaco T 430 high performance cementitious repair mortar is ideally suited for cold weather installations on horizontal surfaces. It can be installed as low as 20° F (-7° C) and has high initial strength and extended working time.
MasterEmaco T 545 very rapid-setting magnesium phosphate-based mortar can be applied in below-freezing temperatures. With fast early strength, T 545 takes traffic in less than an hour and has higher sulphate resistance than conventional mortars.
Falling leaves and blowing debris contaminate surfaces. Add this to longer cure times for single-component coatings, and projects can become difficult to complete in some instances. MasterSeal 914 accelerates the cure of one-component top coats in cool weather conditions to minimize downtime.
MasterFlow 4316 ultra-high strength grout can be installed in temperatures as low as 35° F (2° C). Flowable and pumpable, MasterFlow 4316 has 16,000 psi ultimate strength and withstands temperatures up to 1000° F (538° C).
Best practices dictate that all caulking and sealing be done when temperatures are above 40° F (4° C) to avoid applicaion to moisture-laden surfaces. Moisture on substrates will adversely affect adhesion.
MasterSeal NP 100 high peformance hybrid sealant and MasterSeal SL 100 high performance, self-leveling hybrid sealant can be applied in temperatures as low as 20° F (-6° C) if there is certainty that substrates are clean, completely dry and free of frost, as described under the Surface Preparation section of the technical data guides.
Ucrete Accelerator is an additive for use in UD 200, UD 200SR and DP systems meant to enhance the speed of cure in temperatures as low as 40° F (4° C).
CW Alpha Dry Base Coat is a dry-mix polymer adhesive and base coat containing Portland cement that requires only water for mixing. CW Alpha Dry Base Coat is specifically formulated to use when the job site temperatures are between 35° F (2° C) and 50° F (10° C).
MaxFlash is a one-component elastomeric material for use as a flexible flashing membrane. It can also be used to prepare sheathing joints for subsequent application of Master Builders Solutions air/water-resistive barrier membranes. Cure times will be extended in dry and cold conditions. MaxFlash can be applied to frost-free, dry substrates above 25° F (-4° C), but curing will not be initiated until temperature rises and remains above 32° F (0° C).
