DIRECTIONS

A. SURFACE PREPARATION

1. Suitable substrates are Exterior Grade Plywood (EGP), CSA-0211 EXTERIOR SELECT or (SEL TF) Douglas Fir plywood according to COFI classification or cementious surfaces.
The substrate when placed over conventional floor joists shall be of a design so as to maintain a deflection of not over 1/360th of the span when a live or dead load is placed upon it. The substrate must be to the recommended tolerances of ANSI A108.5 standards. The substrate must be structurally sound, solid, stable, dry, clean and free of grease, oil, paint, dust, tar, wax, primer, sealer or any other substances which may either affect the cure or adhesion of this product. Ensure that the substrate is secured with screws and glued where possible. Ensure that there are at least 3 mm. (1/8“) gaps between the sheets of plywood and all the perimeters of the plywood.
2. Attach a metal lath and ensure that the metal lath is properly and securely fastened with metal screws, staples or nails. If possible, it is advisable to using screws, nails or staples that have corrosion resistance. Butt the joints of the metal lath.
3. It is also advisable to place a cleavage membrane such as 15 lb. roofing felt or 4 mil. polyethylene film on the wooden sub-floor prior to the securement of the metal lath.
4. If the product is to be used on concrete surfaces then it is recommended that the substrate be primed with BONDCRETE 5210 or DYNACRETE 5220 prior to the application of this product.

B. MIXING

1. Use a clean mixing vessel and pour approximately 3.5 to 4 liters of cold clean water and then add 22.7 kgs. (50 lbs.) of DYNACOAT 100 gradually while mixing. Use a slow speed  mixer (approximately 150 R.P.M.). Mix thoroughly to a homogeneous and smooth consistency. Avoid air entrapment by prolonged mixing, which if occurs will lower the compressive strength of the mortar.
2. Permit the mix to slake for 10 to 15 minutes.
3. Re-stir the entire contents of the vessel without adding any more water to the mix.
4. Wash your mixing tools immediately with water after use.
5. Some stiffening of the mix may occur before all the material is consumed. When this occurs, simply re-stir by hand or machine, but DO NOT add any more water.
6. The performane of this prouct can be greatly enhanced by the use of DYNALASTIC 5000, CERAPLY 5010 or DYNACRETE 5220 rather than gauging water.

C. APPLICATION

1. With a flat edged trowel or wooden float, work and screed the mix to completely fill in the metal lath.
2. Ensure that the mortar has a minimum thickness of 1/4“ when floated and that it is uniform.
3. Ensure that DYNACOAT 100 cures at least 24 hours prior to the application of a mortar bed.
4. It is recommended that a DYNA brand of tile adhesive or tile mortar be used for the installation of the final surface.
