LATICRETE STRATA_HEAT 0802-0067-2, Installation Manual

18

When installing the heating cable under tile or stone flooring choose one of the following methods:

1. Single Layer Method: 

LATICRETE does not recommend this method as it is impractical to lay tiles and can cause damage to the STRATA_HEAT™ Wire. However, 

when laying the tiles under the one-step method, start by applying thinset over the STRATA_HEAT Wire with the flat side of the trowel. 

Then add thinset on top of that with the notched side to prepare for the tile.

2. Double Layer Method: 

Embed the heating cable in a skim coat of self-leveling compound or modified thinset, completely covering compound completely covering 

the heating element and the sensor wire. Using a rubber float spread the thin-set over the floor in the same direction as the STRATA_HEAT 

Wire. Ensure that the space between the STRATA_HEAT Wire is filled. Allow this layer to dry completely.
Apply a second layer of thinset or adhesive and lay the tiles as usual. The required minimum total for both layers is 3/8" (9.5 mm) of 

thinset or adhesive. 
When deciding between the single layer or the double layer method you should consider the following: 
We do NOT recommend the single layer method if you will install mosaics or a combination of tiles of different sizes.
If this is the first time installing underfloor heating the double layer method is highly recommended. 

Waiting Period:

Ceramic tiles and stone installations require 1 to 3 weeks for the thinset to cure. Do not switch on the  

STRATA_HEAT floor heating system until you have allowed the thinset material to fully cure. Failure to do so will result in damage to the 

system and cause the thinset to become brittle.

Carpet, Vinyl or Laminate Flooring

Embed the STRATA_HEAT Wire in a layer of self-leveling compound and let it dry. Ensure that the heating cable are covered with a 

minimum of 3/8" (9.5 mm) of self-leveling compound.
Note : The under floor heating cables are NOT approved for direct contact with combustible material. The STRATA_HEAT Wire MUST 

always be embedded in thinset / cement mortar / cement based adhesive glue / tile adhesive before installing floating wood or 

laminate floors.
